Wire burnt in half?

MUDFREAK · 10-09-2008, 02:45 PM

I was on my way home from a ride and I stopped. When I hit the gas again nothing happened. I hopped off and opened up the seat and the wire from the motor to the front and reverse switch burnt in half. What do you think caused this and how do I prevent it from happening again?

Direct short, are any other wires, or battery post have an arc mark on it?

I don't think so but the rubber around the wire is blue and on the part it burnt it is black so it had to hace caught on fire, and the copper was beaded up.

What would have caused it to short?

Vibration will wear the insulation thin then would compleat a circuit, draw heavy amps melt wire. Look for an arc mark on all areas where it ran near where it burned, frame, another wire, battery terminal, motor terminal look where most probable might have been under a battery, look close.

I looked and don't see anywhere else where it arked. Do you think something else is damaged by it arking?

If you can't find a short one or more connections is bad. A bad connection will create alot of heat and melt cables. Very common often overlooked thing on electric carts....especially from new cart owners. Connections need to be checked AT LEAST once a month, more often if you use the cart more often. Most people think once they put them on they can walk away without ever checking them again and that is simply not the case. Checking connections should be part of a maintainence routine just like checking oil in your car.

If in fact it was an arc YES, other components can be messed up.

The motor I have says that it is 9.4 horse D&D. I think I read somewhere that I should be able to do wheelies, is that true?

Not necessarily. Depends on many things, gears, controller, motor, batteries, etc. You can have all the HP in the world but if you can't feed it juice it won't do jack. I have seen high HP motors actually be slower in the low end but build up to speed. (real slow to get up to high speed.) 9.4 HP may be at 5000 RPM. To do wheelies you need low end torque. To build torque with a High RPM type motor you need lots of amps. You also need a high output controller.

Not if you don't get the electrical issue fixed.
Any chance you can post any pictures of the battery compartment and burn area?
