Yes it's an IQ..... The small posts on the solenoid should include a Light Blue wire and a Blue wire with a white stripe. The large posts match your description, but it's the small ones in question. Unless there is an hour meter installed. If so, the Yellow and Red wires will be spliced into the original Light Blue and Blue/White wires a few inches up. Your problem sounds much like a motor stall issue to me. Check the battery voltage across the entire pack. The 49V you mentioned above is low for a "Charged" cart. If you've got a weak battery pack it'll do exactly as you describe. The solenoid will click, voltage will drop, and the solenoid will disengage because it doesn't have enough voltage to hold it engaged. Give me a loaded pack voltage as well. Thanks

The voltage of the pack as of this afternoon was 50.2v. The cart has been sitting since I fully charged the pack last week when it was reading 51v. You are correct about the wires being split as it does have an hour meter. I currently have the positive cable disconnected from the pack as it smoking the resistor on the solenoid. The soleniod doesn't click at all. Thought it was the problem so I bought a new one including the large resistor. Installed it before my original post, but still nothing. Tested with multimeter after install (black prob on yellow, red prob on red) still read 49+v with key off. I was told I should have a 0v reading doing this. Is that true?

You have one of two problems. Either a bad controller or a bad motor. There is a permanent draw or short in one of these two components. Put car in TOW, Unhook battery pack, Remove all 4 wires from motor. Get a multimeter and set it to the Diode Test/Continuity setting. Check to ensure 100% continuity between A1 and A2, and also F1 to F2, and NOWHERE ELSE. If you've got continuity between ANY of these posts and the base of the motor you've located your problem. If you've got continuity between any A post and any F post you've located your problem. If motor passes test, replace the controller and you'll be riding.

Okay, I ran the continuity test on the motor and have posted the results below. I believe the results are telling me the motor is shot, but wanted to run it by everyone on here just to verify.

A1-->A2=001
F1-->F2=002

Motor Housing-->A1=008
Motor Housing-->A2=008
Motor Housing-->F1=Open
Motor Housing-->F2=Open

I hope this makes sense. Anyway let me know. Thanks.

It makes perfect sense. The .008 is almost a direct short. It should be an open circuit with zero continuity.

Replaced motor, it was smoked. Installed today, but still same problem. Based on what TD said if the motor passed the continuity, which it does now, then it would be the controller. My question is, can the controller be tested before I invest in a new one just to find out it is something else? Thanks.

Is the resistor still getting hot even with a new motor that you know is good? If so, it's definitely a controller issue.

TD, yes the resistor is still getting hot. It started as soon as I hooked the pack back up. Working on getting a controller now. Hopefully replacing that will be the end of my issue.
