Need a little trouble shooting. I was able to program the controller with external power, but I don't think I'm getting it power properly from the batteries. I'm pretty sure I've properly put a wire from B- to the diode, and from the diode to the 1st controller input. Is that the way to do...

oy vey, a little embarassing I asked basically the same question back in Jan. Okay, another question. Does it matter which way the contactor is wired? I.e. is there an in and an out side?

quick wiring question: In general the alltrax wiring diagram seems pretty simple. I really wish I could find some real world photos of the same diagram made real, but I think I can muddle through. I've got a Alltrax AXE 4834 and a Curtis Style PB-6 0-5K Ohm Throttle. The throttle has just 2...

Do you need the key switch and emergency stop? The kits usually just have the contactor, diode, and fuse.

project - manco scorpion electric kart. stuff: me0909, alltrax AXE 4834, 36v (old 12v 18ah mower batteries for now). I have a few questions: battery placement - off road go karts, like mine, often have the little shelf thing that's part of the main frame, that floats above the rear swing arm...

I think this old thread answers the battery charging question we both had: http://www.diygokarts.com/vb/showthread.php?t=27511 Basically, you can get a charger for each battery and disconnect them (more work, but maybe cheaper) or charge them with a single charger (matching voltage of course...

Is that single wheel drive with independent suspension?

I'll take a stab at doing the math. Mass = 250 curb weight of manco scorpion = 344lbs (156kg) - maybe 25 lbs less with engine/gas/clutch me = 190 lbs + some batteries and motor (95kg) total: ~250 kgs Fi = m * g * sin(alpha) G= 9.81 m/s² alpha = if you want to go offroad you can assume 10°, Fi...

I'm right there in the same boat. Have a manco roller (pending purchase) that looks pretty clean. I figure its heavy enough (as is my rear) to require a good motor, and that a 1000W and 1500W scooter motors are too weak. I have the same motor in mind, although could be tempted into the...
