1999 wont go

ben_fishn · 08-02-2012, 07:50 AM

a friend of mine replaced his f-n-r switch on his series cart. a lug had come off the old switch. everything was put back correctly but now it wont do a thing. reverse buzzer works but thats it. any ideas what to check?

What does that mean? 'a lug came off his old switch'?

ben_fishn · 08-02-2012, 08:11 AM

there are 4 studs on the switch that the wires from the motor run to. one came off somehow. not sure if it meted off or broke off. he replaced it with a new one and now it wont do anything. just trying to help him get it going.

Okay So the old F&R melted a cable or lug off and then he put a new F&R in and there is no movement...
Does the solenoid click when you try to go?

no it doesnt make a sound other than reverse buzzer. it actully feels like its in a jam.

Get him a wiring diagram from the stickies above this section and have him troubleshoot the solenoid activation circuit. The solenoid must click before we can expect the cart to run.

ok thanks for the help

sent him the info on checking solenoid here is his response., the battery checks 37.1, the batt. side of the solenoid was 37.1 also, the controller side checked 36.1. is solenoid bad?

Likely there is a precharge resistor for the controller on the big lugs of the solenoid.... this will always have power running through it so it is a false test with it on. He could remove it and redo the test? But here is what he should have. with the test leads on the 2 small solenoid terminals, key on, cart in gear, peddle down, he should read 48v+, If not then he needs to determine which side is missing, + or - and then with a diagram troubleshoot the solenoid activation circuit...
I believe the - side of the circuit comes directly and constantly from the OBC. If it is not present try installing a jumper wire to provide 48v neg to the small post were the yellow wire is,
Then the + side should come from the MCOR through the F&R micro (red with white stripe) so it could be a bad micro...
Atleast that's the way this ezgo tech remembers it, LOL
