07 DS Relay Clicks but no go

borko1

Hi, everything was working fine until today. Batteries are in decent shape 12.6v - 12.8v. Best described as follows:

1) Depress the petal and the relay clicks like always, but no movement and after one second or so I hear another click, (maybe the relay disengages?).

2) I thought clearing the computer might be worthwhile so I switched to tow mode, disconnected the neg terminal from the battery and let it sit for an hour.

3) I reconnected the negative to the battery, switched back to run, keyswitch to on, then rockerswitch to forward. When I pressed the petal the yellow battery lamp illuminated for about 5 seconds then went out. Continues to behave like #1 above. Only happened one time.

4) When I push the cart with the switch in run mode I do not get the beeping that I always did in the past. Maybe this is related to the regen circuit.

I'd really appreciate any help in getting this figured out. I'm hoping I don't have to take it to a repair shop...

what your hearing is the reagan solenoid click not the master solenoid......so you need to find out why could be as simple as a bad microswitch or a bad solenoid so you,ll need to test them.........you can try jumping the master solenoid see if cart runs its the one that dosn,t have the resistor coil mounted in front of it................................

Shadowman, it's an IQ... only one solenoid.

you say the "Relay" is clicking..... Are you referring to the solenoid?

I think you've got a bad MCOR.... Plug the charger into the cart and let it turn on. Unplug it. Put it in reverse and see if you've got a buzzer now. I think your system is asleep and won't allow the walkaway braking to function properly. Once it's awake you can jump the two pin plug that plugs into the MCOR to force the solenoid circuit to close. If it runs while jumped, replace MCOR.

Good news !! I discovered what the problem was.... I decided to get brave and remove the controller cover. What I found was that the blue wire was not connected, just hanging there right next to the pin it came from, can't imagine how it would come off but it did. I switched to tow mode, disconnected the batteries, re-connected the blue wire, reconnected the batteries then back to run mode .
When I turned the key to on the yellow battery indicator lamp came on. When I depressed the petal with the rocker in FWD the lamp went out and away I went.

Thanks for all the help !
