1988 ds 5 solonoid resistor getting cherry hot

[typical.t]

I have a 1988 ds that I bought. you could tell that the resistor area got hot the paint was burnt both middle batteries where melted replaced all batteries as soon as I hook up the new battery the cart took off full speed ( I had the cart on jack stands) I shut the key switch off still ran F&R switch did not help. did some testing found that the last solenoid on the pass side was stuck open replaced retested no problems. I lifted it w/ a 6" lift w/ 22x11r10. Now the first resistor on the driver side cherry red melted brand new paint job cart wanted to take off when I stop. the pedal Assy. is not froze move like it should
Do I have more then one solenoid stuck open? I know bigger tires means more stress on everything. but I did this without the bigger stuff.
