S2 motor cable overheating

[CV4Golf]

Hi,

I have been working on a 1992 club car 36V resistor coil cart. It has a high speed motor (brand unknown). I upgraded all of the motor/v-glide/forward reverse switch cables to 6 gauge. I also put in a new v-glide, solenoid and forward/reverse switch assembly. The cable running from the S2 motor terminal to battery 6 neg. gets dangerously hot. You can even smell it while driving the cart. This is at full throttle, which I thought should dissipate the heat. I also have my reducer connected to the same battery terminal along with the fuse wire. I believe this all to be correct set-up? Is it that the upgraded motor is too much for a resistor coil set-up, and I need to convert to a controller? Or could it be as simple as switching out to a 4 gauge cable?

Thank You for any suggestions.

What order are your terminals on the battery post?

Fuse on bottom, reducer in middle, motor cable on top.

Saw where you were going with that question. Changed order to largest to smallest terminal connections beginning with the motor/battery cable on the bottom. Works perfect now.

Thank You!

Yeah the way you had them before with the smaller wires between the battery and motor cable was creating a smaller contact area which equals more resistance.
