    Testing BBSHD controller

    I did not find any troubleshooting threads before I posted.

    Just installed new BBSHD in fat tire trike. When I powered it up for testing, I heard a brief, very faint sizzle sound, the display powered up then off. Now I have nothing. The 30A fuse did not blow. I put jumpers between the anderson power poles to see if I had a loose connection. Still nothing.

    Battery has full charge.

    Any way to test the controller with a multi-meter before I replace the controller? My main concern is spending $ on another controller and frying it also. I cannot find any bad connections, but impossible to be sure due to no power at all.

    Good stuff in the Knowledge Base for BBSxx… I'd start here.
