Yes, there are no other wires. Wires go from battery to the pedal, then pedal to 2 light switches that activate the motors either forward or in reverse + one wheels vs 2 wheels, there are zero relays or circuit boards I can see unless there is something inside the pedal. That is the bit I am bypassing (the selector).. ... Nothing is fry-able except wiring I guess, the motors both still work... the pedal still works too as it gives me progressively more voltage as I press harder... I'm stumped as to why I'd see correct voltage out of the pedal but once I connect that output to a motor I get nothing... must be wiring then, it shows V but cannot take the load ???? Still when I plug those pedal wires to a motor the V goes to zero. Again direct battery, they work...

I'm surprised the motors can take 18v. Don't stall them.
Oh yeah, there's a whole hobby of pushing those to 24v + , my 18V mod was a joke and both motors still work fine, either the pedal is lying to me or it's a wiring issue... Thanks for you offer but my motors are good as far as I can tell and there is no real gearbox there. Frankly this thing has lived a good life, wore out a front end hitting sidewalks (replaced) and 2 sets of rear wheels worn to the max - I'm ok trashing it but I'm annoyed I can't figure out what's going on ;-) This should work ;-)
