It is my understanding that the output voltage at the 3 wire plug that powers the brake lever cutoff is 5 volts. If so, does anyone know the amp reading?
Thanks.
Thanks.

It may help if we knew what sort of a controller you were dealing with and what you are trying to do. I believe the 5v is available there for use with a hall sensor which not all levers and sensors use, some are just a reed or mechanical switch. I'm sure they are all solid state devices so something like 250ma would be on the high side.

Thanks for your reply. Thinking of making a patch to use this 5V 250ma as a charge current for a Garmin.Comment

Unless someone else knows for sure I don't think I would try and use any of those ports for something like a usb charge port. There are some power converters out there that can take 52/48 down to 12 and 5 but they are not tiny or cheap so for the specific use of USB port seems like the displays would be the cleanest easiest way to go. Note for future builds besides the display there are some battery packs that have a USB port on them.

All of the 7 tandems and 4 trikes I have converted to mid drive are from Luna. This set up is on an BBSHD with one of your hard case 52V 17amp battery.
Thanks, Bob.Comment

Thanks Paxtana. I will look at the two displays you noted. A lot less work than putting together a patch cable.
It is 'quite the fleet' and enables our older riders who have yet to go the eBike route to draft along and maintain a tight paceline. At 25+mph those with eTandems do a lot of 'motor pacing' with singles who are training for our local Senior Games. It is better than being stuck behind a moped.

Hello all - I am new to this site and ebikes in general- I did a search but didn't see an answer to my question (though I thought I would...)
I just got my Luna Fat Galaxy with the Ludi option and a 750c display and am really enjoying it. I do find that I am often wishing for a little more boost when I have my controller PAS set at a 2 and a little less boost when it is set at 3.
I do enjoy peddling, but I often find that at a setting of 3 I am going faster than I want to at the high gears or if I down shift to limit the speed, the assist provides so much power that front sprocket is spinning too fast for me too keep up with comfortably .
I think it would be fun to be able to tune the levels to my riding style and size (I weigh 265 lbs)
Is there an easy way to adjust the power at each setting through the display settings?
Thanks for your advice.

I think you will like it when you get it set to 9 steps. You sound like a very similar rider to me and at first I hated it, it was either not enough or too much when it was on 5 steps and I was ready to dig into the programing cable but as soon as I went to 9 I have never bothered to mess with the cable.

Hi, I'm following Rodney64's thread and I note that his Specialized Enduro is a large frame and the battery fits. I have a 2009 Specialized Enduro Expert, medium frame. I've already tried my lower profile EM3ev 48V (13S4P) Super Shark Ebike Battery (96mm high x 368mm long) and it does not fit. Does Luna have a 13.5/14Ah battery that will fit inside the frame?Comment

Sorry we don't really have specific information on stuff like that, unless it is already on a build thread it's anybody's guess.
You might try the PDF mockup of our Wolf battery, on the Wolf listing. It can usually install into smaller areas than shark. If nothing else you can usually install it on the underside of the downtube.

Hello, I have Luna BBSHD off road w / Dire wolf kit that just wont fire up. I've obviously missed something I've gone through the troubleshooting guide. checking connections, replacing main wire harness and display (500c) which i just received from Luna very quick shipping, Thank you. checked speedo spacing . I made a jumper to power the motor with charger in-which it did run. both Displays will blink on for a split second then go blank. I tried to bypass with the programming cable, nothing. I just can't seem to connect the dots, maybe the controller??Comment
-
Did it ever turn on, or is this a new build?
Have you tried plugging into the other discharge port on the battery? Please try that and FIRMLY plug it in. Sounds like some power is getting to the controller but not enough to power it on. Which could be caused by something like only partially plugging into the discharge on the battery and burning out the antispark resistor as a result.
If you got voltage from the battery and you have ensured you have a normal, good connection to the controller, then you may indeed need a new controller.
-
Thank you for the reply. The build is a year old and ran great all last summer. I was getting it ready for the spring. I have used a a multi meter on every connection point from battery to the motor, voltage is 57-56. I do not know what the voltage is supposed to be coming out of the controller. Thank you again, Ill order a controller and try that.

While examining the connections under the side cover of my X1 I noticed the 8-pin higo/julet connector was loose. When I explored further the connector unplugged way too easily and on the harness side all 8 pins were bare with no shield or casing. Is this normal. When I looked online for similar connectors I found that a similar connector has a formed shield on the end. See pics. I turned in trouble ticket (order# 146790) but didn’t get a receipt email yet. Is this cable an item that can be ordered or provided?. Thx

Thank you....I figured you were backed up on the trouble desk and I figured you would want to see the pic (didn’t see a way to attach a pic to ticket)....I had already checked the receptacle for the remnant but didn’t find anything (it’s the one in the 2nd pic) that’s what was so odd and what prompted my question....anyways thanks again, hope to hear from you on a replacement path... Best, Steve

I have a Luna 750C display that just started to flash on, then immediately off when trying ride my bike. It has a BBSHD motor and a Shark 52V battery. The charger says the battery is charged.
Any thoughts?Comment

I would use the troubleshooting guide on the knowledge base to determine if it is the display or not, by either using a different display or bypassing the display with program cable or jumper. If you determine it's the display then it probably needs replaced. If you determine it's the controller that probably needs replaced instead. If you determine it's power issue then you might need to adjust the contacts on the bottom of the battery

I just completed installing a Luna Bafang ultra kit on my wife's Catrike. It's worked great for about a week but now there is no speed output to the display, it shows 00.0 mph no matter how fast I go. It also has a much diminished power output and very little assist. All assist levels are about the same. I can't believe the cable would go bad in one week. Do you have any idea what may be happening? Is there a known speedo problem with the G510? Thanks in advance for your comments.

Assuming it was not damaged in some way the controller is probably faulty. Please file a support ticket https://lunacycle.com/support-request/

I have a number of intermittent problems with my BBS02 kit. I have cleaned contacts, checked cable connections, cleaned out the out controller area. Problems occur with or without the throttle connected.
Frequently the display and motor powers off, sometimes after running for a half hour, sometimes immediately after first powered on. Sometimes switching the battery on and off several times fixes it, sometimes I can power it on after pedaling a number of minutes.
Sometimes the display is on but the motor won't run.
The latest problem is that sometimes the motor continues to assist even when the display shows pedal assist is set to zero.
Any suggestions on how to troubleshoot this would be appreciated.Comment

An intermittent problem which occurs at all speed/power levels could be a loose connection or short in throttle, brake cables, gearsensor cable or connectors between controller>motor. A problem that only happens at high load is more likely to be something getting hot. Which could be a high resistance connection or short in the power wiring, or an overheating controller, an overheating battery, or a battery that is showing voltage sag beyond Low Voltage Cutoff, or shutting down from pulling a higher discharge rate than the built-in battery management system is built for.
Would also be advisable to remove any accessories, unplug gearsensor, brake sensor etc.

If nothing else just start throwing parts at it; there are only a few things it can be and only so many parts you can change out -
I would carefully inspect the wiring looking for any signs of pinching or damage. Start right where they come out of the motor. Look close at places where it could have been damaged by bottoming out on terrain or maybe putting the bike in a stand or on a rack. Pull the main harness connector apart and inspect that for any signs of water or other crud that could have got in there. Check the rest of the harness for any damage maybe caused by the bars getting spun around or again pinched against something. Maybe even try a new upper main harness? The lower part is part of the controller which would be next on my list if the upper doesn't fix it but is a more expensive part so I don't know that I would buy one just cuz.

I submitted issues with my Shark 52V battery yesterday. Thanks for pointing me to the 07/14/2017 about the battery and possibly the BMS being tripped. I looked at the following website Jumping your Luna Shark Battery Pack (lunacycle.com) and it shows how to reset the BMS. My charge doesn't have the same type of barrel end. It's a larger barrel type with multiple inputs. Do you have a plug with a red and black wire out of it I can use per the instructions? Thanks.......AndyComment

Does your multimeter show correct voltage at the discharge contacts? If so you do not need to jumpstart it.
If you are using a standard charger with xlr on it, i.e. it is not using some kind of adapter you can unplug, then it would probably be difficult to jerry rig wires up to the discharge contacts. At least not without cutting off that connector and running the bare wires to the contacts, then soldering it back together.

I have a BBSHD tuned programmed at 750 watts. When I want to pedal with the motor turned off, I feel resistance from the motor. Is this normal? Secondly, can I reprogram the controller to give me less power in the various power levels? What are the default settings for each level when the kits (tuned fo4 750 watts) are sent from Luna? ThxComment

With the motor off or set to zero assist there is more drag on the pedals than if there was no motor at but it should not be so much that you really think its causing a problem. My non scientific impression is all the extra weight of a battery and the motor adds more drag to the overall experience than just what you get in the pedals. Take the chain off and test it again. You should be able to pedal with just a pinky finger. If you have more drag than that you may have a defect or something causing a bind. Do you have a gap that you can slide at least a piece of paper through between your chainstay (the bike frame that goes to the back wheel) and the gear case of the BBS? If no that could be your problem, you are actually bending the BBS's gear case.
For the power levels go to the more or advanced settings screen and set the assist levels to 9 from the default 5. Most of the displays this screen is the same one where you set the tire size to make the speed and odometer accurate. Going to 9 levels doesn't change the min or max boost but gives you finer steps. Many of us didn't like the five steps and were thinking we would have to get the cable to do advanced programming but after going to 9 are happy,. When I was on 5 it always seemed like there was too much and I was always accelerating.Last edited by 73Eldo; 04-11-2021, 06:31 AM. -
Try turning the display on with the battery turned off(if it has a switch) or with the battery unplugged. If the motor isn't running then it's going to try to generate power when pedaled while it's off. The capacitors in the controller store enough power to keep it excited. Just like an automobile alternator, it spins easy when the field isn't excited. But feed it 12v and it doesn't spin so easy.

73Eldo, thanks for your response. I will try both of your suggestions.Comment

Ok I have a 52v dire wolf pack with bafang hd mid drive & color display, approx 1 year old, properly stored (80%) and cared for, maybe 50 charge cycles.
Battery voltage and display read 44.7v (1/4 bar) tried two different Luna chargers with approx 58.2 volts tested at output. When plugged into battery, both chargers set at 100%(or any other settings), indicate batteries fully charged! Will not Charge.Comment
-
If it is still showing 58.2 on the charger then it is not connecting for some reason. If the chargers work on other batteries then maybe something wrong with the charge port on the battery. Have you tested the charge port for voltage with a multimeter? Have you tried the backup charge port?Comment
