I have a 89 EZGO golf cart, (s/n 534071) with resistor coils that was smoking and smelled hot while sitting still with foot on throttle pedal. After reading and searching for three days on the forum I now understand why. While troubleshooting to see if I could get them to stop glowing red I noticed that the speed board was arcing when it transitioned between the second and third contact. This morning I cleaned the contacts (they were dirty with slight corrosion) on the first attemp to see if the arching problem had been solved I found myself with a nice little fire... yes it still arcs, quite nicely too. Things I have also noticed that may or may not be relevent. I have noticed that where the cables connect to the coils the front two connections spin as if they are loose, but the nuts are tight, the third and fourth connections are tight and do not rotate. Battery charges on this cart last only a very short period, the batteries are old and do need replaced. After charging the batteries they do have proper volts. I am open to any and all suggestions, even upgrading from the coil config. if the price is right. fairly handy with mechanics, but not very familar with carts. any help would be very much appreciated. thanks in advance. BTW great forum.
