Need help with 2005 Precendent

55BigBlock · 07-25-2015, 01:38 PM

A friend picked up a 2005 Precedent 4X12. It wasn't running. He bought 4 new T1275 batteries. We installed them today. The microswitch in the MCOR clicks. The MCOR measures 1100 ohms at full throttle. The solenoid clicks. The reverse buzzer sounds but the cart won't move. It has a 1510-5201 controller. Everything in the wiring looks good except a diode?? in the big yellow wire off the solenoid. I don't know what it does. I have not reset the OBC. Is there anything I'm missing before we start looking for a controller? Any ideas are really appreciated.

Note, The diode?? I mentioned is device #29 on post #14 on the sticky Club Car Wiring Diagrams.

Check for motor continuity, that will help to eliminate a motor issue. make sure the solenoid is really working. Not sure what yellow wire you are mentioning.

Unless I'm reading this wrong. That diode has no connection to the big wires on the solenoid. It's connected between the small wires on the solenoid. I'll see if I can find a picture. You aren't thinking the precharge resistor is a diode are you. It connects to the large terminals. PS some of the large wire colors are different since I upgraded.

No it's not the precharge resistor. I am calling it a diode?? I don't know what it is. It is about 1 inch long 3/8 dia. and black. I can't post pics with this laptop. In the wiring diagram sticky it appears to be device #29 on post 14. See diagramhttp://www.buggiesgonewild.com/elect...iagrams-2.html

Place your ohm meter across it. Both directions. If its a diode it should read open one way and about 500 ohms the other. If its a resistor it should show some resistance. If its shows a open circuit remove it because it doesn't belong there.(it may have been a fuse).

After taking a hard second look it was the resistor. It measures 248 ohms.

I checked the motor and got about 1250 ohms between F! and F2 and 5 ohms between A1 and A2. No shorts between the case and any terminals.

I have no idea what the resistance readings should be but sometimes even through the solenoid clicks it doesn't mean it's working. To check remove all of the wires off one of the large terminals. Connect your ohm meter across both large terminals and activate solenoid. The reading should go from open to zero ohms.

I'm going to check that in the morning. If it checks good I think a new controller is in order.. Not a bad deal for a free cart. New batteries, new controller equals one 2005 Precedent. What a deal!!

Anybody got a 1510-5201 they want to sell????

If you don't find one check the new one out that Scotty b sells.

While we are waiting to hear the outcome tomorrow I'd like to ask a question. Has anyone else noticed that Club Car uses a 250 ohm precharge resistor on their 48v carts? All the literature I've read calls for a 470 ohm resistor for a 48v cart. Does it make any kind of difference?
