The charger not coming on, is sign that the primary circuit is not complete. What is voltage at the carts charger connection? Is it same as battery pack? It should be.

Expert:  Curtis B. replied 1 year ago.

Do you have 36 volts on both cable terminals of the solenoid?

Customer: replied 1 year ago.
have 36 volts on cable ends at the solenoid, have 37.6 volts at the charger socket
Expert:  Curtis B. replied 1 year ago.

If you have 37 volts at the charger connection, the charger should come on.?? Was charger working before?

Customer: replied 1 year ago.
but these batteries are fully charged
Expert:  Curtis B. replied 1 year ago.

Where do you have the posiitve battery cable attached? And where is the negative cable attached?

Expert:  Curtis B. replied 1 year ago.

Charge would come on, even if batteries are fully charged, It would not stay on long. But it would start!

Expert:  Curtis B. replied 1 year ago.

Charger

Customer: replied 1 year ago.
on the charger socket the white lead is on the positive post and the black is on the negative
Expert:  Curtis B. replied 1 year ago.

That is right, But where do the cables off the battery pack go to?

Customer: replied 1 year ago.
they go into the controller where ive got good voltage and polarity is correct, the positive lead jumps over to the solenoid
Expert:  Curtis B. replied 1 year ago.

Positive lead has to go direct to the solenoid. the resistor lets voltage cross solenoid , and then to the controller B+, Is the resistor good? Have you ran a solenoid test?

Expert:  Curtis B. replied 1 year ago.

What does charger do when plugged in? Nothing or does it run series of lights and never starts? Have you had the cover off it?

Customer: replied 1 year ago.
ok this solenoid has two resistors one is across the big terminals (primary circuit) and one on the control side, this cart has always been wired this way I just put the wires back on the controller the way they came off never took anything off the solenoid,
Customer: replied 1 year ago.
this is an old power wise charger no lights just an amp needle
Expert:  Curtis B. replied 1 year ago.

The resistor across the big terminals is right, Not sure why there would be another!

Customer: replied 1 year ago.
haven't checked resistors or the solenoid
Customer: replied 1 year ago.
this is a 2004 ez go 36 volt txt , the diagram you sent is what ive got
Customer: replied 1 year ago.
isn't what ive got sorry
Expert:  Curtis B. replied 1 year ago.

Here is Ezgo tech with trouble shooting. Scroll down the opening page until you see the test section. Do not go to the manuals,

Expert:  Curtis B. replied 1 year ago.

WHat is different on yours, What controller do you have?

Expert:  Curtis B. replied 1 year ago.

With the car jerking and then quit, you can have a bad drive motor. I would test solenoid and do the drive motor test.

Customer: replied 1 year ago.
controller 25864g09 Curtis 36volt 350 amp 5 pins
Expert:  Curtis B. replied 1 year ago.

That is the Ezgo number fr the 1206 controller. Should be the same! 5 pins is performance option.

Customer: replied 1 year ago.
correct only 4 are used

Customer: replied 1 year ago.
think problem is at solenoid even if I have a bad drive motor solenoid should click correct?
Expert:  Curtis B. replied 1 year ago.

Yes , the foot switch should close the solenoid.

Expert:  Curtis B. replied 1 year ago.

Charger seems to be a complete different problem.

Customer: replied 1 year ago.
ok then how does the foot pedal control the speed rheostat thur the controller
Customer: replied 1 year ago.
think charger is not working , it should kick on for a second or two
Expert:  Curtis B. replied 1 year ago.

Yes, the ITS has two functions, one is to close the solenoid, second is to control speed through the signal it sends controller.

Customer: replied 1 year ago.
ok then problem could be with solenoid and resistors and ITS
Expert:  Curtis B. replied 1 year ago.

Everything has to be correct, or it will not run. I would test each component, before ordering parts that I don't need.

Expert:  Curtis B. replied 1 year ago.

Do you have a friend you could plug your charger to his cart to see if it works? That is always a quick test to see if charger is good.

Customer: replied 1 year ago.
I AGREE, YOUVE BEEN VERY HELPFUL WILL TEST EACH component Thanks!
Customer: replied 1 year ago.
no I'm the only one in the neighborhood with a 36 volt cart
Expert:  Curtis B. replied 1 year ago.

OK> I'm off to bed!
