Re: Variable Regeneration Voltage Questions.

Or just: Using the brake cut-off on the controller will apply a baseline 20% regen torque which can be increased by varying the throttle between 1.0V-3.5V while braking. which means you engage the ebrake lever (or switch) and then use the throttle to vary the braking force from 20% at throttle off o...

Re: switching power supply as DC/DC converter...issues???

I had to go with incandescent turn signals on the rear and LEDs up front, since the little motorcycle blinker relay I picked up wouldn't respond to LEDs only. You can add power resistors in parallel with the LEDs to fix that. Autoparts places around here often sell those "ballast resistors" along w...

Re: Zip Tie Failure

The two main environmental issues with zipties are UV quickly degrading the plastic, which makes them brittle, and cold, which makes them brittle. How cold will depend on which plastic is used, how much "plasticizer", etc. Most zipties don't have any (sigificant) UV-protection so they fail from that...

Re: switching power supply as DC/DC converter...issues???

Assuming the keyswitch is connecting battery power to the "wallwart", first thing I'd do is bypass the switch providing the power, and then connect/disconnect the power wire manually and see if it turns on every time that way. If it does, the switch is the problem (possibly arcing inside at the high...

Re: How to reverse motor direction - old Chinese car

Controller has big 23pin signals connector. One of wires is probably FWD/REV function. Unfortunatelly I have no idea which one.

That and/or figure out how to reconfigure it so that the bike will operate without it. It'll power on and operate the motor without one as long as you short the battery-out and switched-battery-in pins together. Sometimes you also have to short the two data lines together.

I am quite sure that all wires are reconnected to the same places.

Perhaps you didn't read the other info posted above, but this is a geared motor with a clutch. With a gear motor that has an internal clutch (almost all of them) it can't make any difference at all.

Just so you know, in case you're needing them for a DC application: Regardless of what that page tries to tell you, the big breakers on that page are designed for AC, not DC, so they are not guaranteed to actually break a DC connection under load. They might, or they might not. You can look up the p...
