Might try taking the plastic cover off your "accelerator speed switch", the moving contack arm could have been damaged/broken.

yep checked that ,its hitting all contacts . thanks for the reply.

I'm guessing now, but is the G5e a resistor coil speed control? IF yes. The throttle speed wiper contacts should be inspected for damage and alignment problems.

Put the rear on jacks, is the solenoid clicking when you try to go? If not, check the solenoid activation circuit.

yep , will check contacts ,how could i clean them ? (sandpaper or emory?) . dont think i heard the solenoid click . should i get 36+ volts through it ? thanks

yes, but be sure you are not just reading the resistor. You might want to remove it for testing, to be sure.

Solenoid click (good call Scotty) There are 2 small wires to activate the solenoid. Black should have 36 volts negative all the time, if no voltage check the main negative fuse and connections, if voltage drops when the key switch is on and the accelerator pedal pushed, bad ground in the wire harness. The red wire activates the solenoid thru the batteries/fuse/wireharness/key switch and the accelerator stop switch (no resistors or diodes on Yamaha solenoids to worry about). If you test 36 volts negative (all the time) and 36 volts positive (when you push the accelerator pedal) at the solenoid, bad solenoid.

thanks guys for the advice , the cart is at our camper where we go on weekends. will check cart this weekend and post findings . if u think of any other things to check if the solenoid is good please advise .thanks (we have no internet service at lake )
