2015 ezgo electric cart will not release brakes/hear all the clicking noises/tried the #1/#3 wire release but did nothing

SOURCE: Electric Golf cart only shutters and inches forward

so many possibilities...

does it roll fairly freely? (checking to see if the brakes or rearend seized up)

Are there any "bad" sounds like things grinding? (Connection between Motor and rearend, axle splines...)

If all that is solid, it is likely in the controller.... (it takes a solid charge right... No bad batteries in there or loose connection? might want to check all the battery connections to make sure none are burnt...)

1997.. does it have the electonic speed control by that year? the other possibilty is that the accelerator is not working corectly. they used a resistor system on old ones that has contactors that would get worn out.... Newer ones control a potentiometer(sp) that controlled the speed.

Only a few real components to check, but if you are not mechanically and electically inclined, could be tough to isolate.

peace,

Regular 90 weight gear oil. Fill until it reaches the fill hole.

Most people do not trust the old oil pump used on the 3PG models, me included. Mix 50:1 and you can be sure that the piston and crank will not seize up.

Your batteries have died. The reason it will barely move in reverse is that current is being supplied to the motor is a direction that it spends very little time using. There is a slight change in the armature over time, and reverse tends to work better over time. Check the voltage when under load. (run jumper wires from the + and - of the battery bank. If it is a 36 volt cart and the voltage drops to below 36 volts, you do not have enoug current to run the cart. Plug in the charger and watch the ampmeter. If it goes up to about 20 amps, then it is charging. It should take a good charge after 10 hours. If the cart charges and only runs a short distance, the batteries need replacing.
