Forward or Reverse only

[kritter1]

Cart failed to back out of the cart shed . Placed it in forward and had power. Back into reverse and nothing.

I have a 2006 EZ GO TXT with a GE 5HP motor, Altrax 400NPX controller, HD solenoid, 2 AWG wiring throughout entire cart.

I have not had any trouble until recently, when it didn't go when switching the FNR. a little playing withj the handle made contact and went on normally.

I tested voltage to each post on the FNR switch and got 38.6V. To the motor and got 37.2V on each post . Micro switches had 38.2V when in forward and reverse. Have continuity between microswitches.

Cart has reverse up when wired with B to motor S1 but no forward, and will go forward when wiring at B and D to motor S1 is switched, but no reverse.

All connections are tight and no signs of burned wires. A week ago the cart smelled hot like something was overheating. I checked under the seat and found nothing

Next?

Tighten 1/2 turn the 9/16ths nut on the center pivot shaft B in the attachment.

I replaced the FNR switch with a HD rebuilt one and same problem. I tightened the center 9/16" nut tight and backed it off 1/2 turn. No change

" A week ago the cart smelled hot like something was overheating. I checked under the seat and found nothing "

My guess is the F&R got too hot and the contacts sunk in the plastic housing.
Post a pic of the cables bolted to the terminals if you can. Otherwise look for any signs of heat, all 4 terminals and cable lugs should be the same color.

If that fails to shine a light on the trouble remove the center pivot shaft and post pics of the 4 cam contacts and the 4 housing contacts so we can see wht you have there.

I will do that, but I have a different FNR switch in now and am having the same problem.

I did cbriefly check the contact on the one I removed and didn't notice any problem, but I will take it apart

Okay - I was concentrating on the burning smell being the problem...lets back up... When you try to go does the solenoid click? Does the controller LED flash?

[kritter1]

Yes the solenoid clicks when in either F or R and the LED flashes. I thought maybe a wire had lossened and caused the smell but all were tight

[scottyb]

Does the control flash 4 green the go solid green?
Does LED turn orange color at full throttle?

[kritter1]

I'll check that in a few minutes. Heading out to play in a league tonight. Will check and report when I get home.

Back from golf. The control flash does blink green 4 times and then go solid. Haven't seen what the LED does at full throttle. Will check it tomorrow
