Default Re: Club Car IQ solenoid always engaged

I was just looking at the diagram you posted for me and I see coming out of the MCOR there is a "sonic weld" somewhere in the harness. Is it possible that is causing my issue?

I assume You have the OBC plugged back in again, correct?

You need to measure individual battery voltages at this stage (close to charging cycle end), You may find a bad battery, meaning way lower in voltage than the other batteries.

You have some wiring that is wrong in there.

The Controller provides the negative to the solenoid, it seems very unlikely that both of Your controllers, from two different manufactures, have the same activation issue.

Can You post a picture showing the solenoid wiring?

I know You said the solenoid Blue/White wire goes directly to pin #13 of the controller 16-pin connector, but it does not appear to be the case.

You can test the voltage on the cold side of the key switch, it should be +48v with key ON.

You can also test the voltage on the Blue wire going to the MCOR 2-pin connector, it should also be +48v with key ON.

Any reference to +48v should mean within 0.5v of actual pack voltage.

Busy day here at work, but I will check again later this PM.

I appreciate the response. I'm at work now but I'll do some more looking and take some pictures in a little while when I get off work.

Here's a couple of pictures of the solenoid blue/white wire and where it plugs on the controller.

I only have 18 volts at the key switch.

I unplugged the obc for 10 seconds and checked it again and I have 42 volts at the key switch.

I don't know if this manners or not but I don't see a precharge resistor. Don't let any stone unturned.

It's there, it's just tucked underneath the solenoid.

I don't understand what makes it run when I unplug the obc for a few seconds and plug it back in. I have to hit the throttle immediately after I plug it back in for it to engage the solenoid. If I plug it back in and wait a minute it will not run. Then once I let off the gas and the solenoid opens it will not engage again unless I unplug the OBC. This thing is a nightmare!

That Red cable on the solenoid big post looks pretty close to the frame, I assume that is the one that goes to controller B+.

Make sure is not making contact with the frame since the OBC negative on the older versions was in contact with the frame.

Also, is the pack negative cable going thru the OBC?

As jjance mentioned, You should have a pre-charge resistor on the solenoid big posts, it will not cause the cart to not run, but it will cause premature failure of the solenoid contacts.

It may be just the angle of the picture, but the pink wire coming off the big solenoid post where the pack positive connects to looks pretty small.

The cable is not touching the frame but you're right it's close.

The negative cable does run through the obc.

The pre-charge resistor is in place it's just tucked under the solenoid.

The pink wire is a factory wire.
