Funny you should mention it. An gunna wire up my E 20 today. I
stripped
out ALL the old wires so I'm on my own, putting them back. Have Alltraxes'
schematic to go on, running new wires as needed. He, Alltrax seems to hook
stuff up to the old wiring system, that he assumes yur keeping. My delemma
of right now is to decide what throttle systen to use, like a hand throttle
or a foot pedal. My olde MTD gas one used a throttle on the " dashboard"
was
happy with that, but it was a gas with a clutch. What did you guyz do? I
mean with the Altrax setup, potbox? Keep thr foot pedal?Like keeping the
clutch in an EV car, a matter of personal preferance?
