ezgo 36 v series whats wrong with th pic

Thimmesch1 · 08-19-2017, 02:19 AM

i just bought a 36 v ezgo. advertised as new batteries bad motor.
he explained it stopped working so he bought new batterys and that did not fix it.his golf cart guy came out and pulled the motor and there was black dust all over it and that proved the motor was bad.
As we pushed it on the trailer i noticed there was one side that was locked up, so i when i got it home i pulled the brake drum, chiseled out a bunch of mud & gunk(the whole time hooked to charger)
once the frozen hub was released from the cart i hit the peddle and it spun the wheels in forward and reverse.
i continued to charge and now it does nothing when i push the throttle

notes; when i turn the key on the solonoid clicks(turns off when i hit N then clicks back on.i hear no sound when i hit the peddle??
Thanks

Let it charge until the charger shuts off. Monitor it (since you just got it and don't know if it's gonna burn down your garage, don't let this unknown thing charge unattended overnight). After that, see what happens..

This may be a silly question: You DID unplug the charger when you tried to run it again, right? The reed switch in the charger socket will prevent it from running if the charger plug is still in the socket on the cart.

it ran with the charger plugged in?
and it charged to 38 volts and shut off .the lowest the amp meter showed was 15.

the voltage has dropped to 37.2 this morning,when turned on the blue thing gets really hot, with it in forward key on the voltage across the solonoids big posts are the same(37.2) when i measure across the small post one is 37.3 and across the resistor it is zero?

the voltage has dropped to 37.2 this morning,when turned on the blue thing gets really hot, with it in forward key on, the voltage at the solenoids big posts are the same(37.2)with the key off it it reads 23.8 on the controller side.
when i measure across the small post one is 37.3 and across the resistor it is zero?

where does this big white wire connect to? coming from the F/R switch.

Thimmesch1 · 08-19-2017, 01:01 PM

more readings...
with key on all lugs on F/R switch are at 37.2
key off they read 24.7?
same thing on the controller except the far left is ground.
no reed switch
Did i burn something up when i ran it with the charger connected?
Thanks
