Controller Trouble Shooting

After testing the battery, micro-switches and motor and not finding any problems, that only left the circuit board with the relay that could be bad. First I de-soldered the relay from the board and was able to test it and it worked fine. The only other problem that it could be was one of the resistors, diode, capacitor was bad. I do not have the knowledge or experience to troubleshoot these so I studied the layout of the board and came up with a "work a round". This work around DOES NOT affect the charging in any way, the micro-switches including the brake still work as designed. All it does is bypass the resistor, diode, and capacitor which I do not know why they used them on such a simple electro-mechanical device like this relay (you usually see relays used without them). Anyway, the bottom line is the fix works, they run great, recharged great and ran great again. Why I got two silver scooters with bad boards I don't know, but in a pinch you can share this fix with someone who has a board that goes out and the relay is still good.

All you do is take the black wire that goes to the receptacle that you plug the recharging transformer into. About 1 1/2 inches from where that black wire is soldered to circuit board, strip the insulation so you have a bare wire exposed. There are two white connectors on the board (on the reverse side, the micro-switches from the brake and "go" switch are soldered here) Solder the exposed black wire TO THE PIN THAT IS CLOSEST TO THE EDGE OF THE CIRCUIT BOARD. That’s all there is to it. All this is is a shunt to the relay so it can function properly. Hope I wasn't to lengthy and I hope this helps you.
