Re: 01 club car regen wont move
For the record, here is the procedure to test the MCOR with a volt meter.
This is from an IQ manual for DS, but it's the same procedure and voltage for any MCOR. MCOR Voltage Test without the IQDM Handset 1. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position jack stands under the frame crossmember between the spring mount and side stringer, just forward of each rear wheel. See WARNING “Lift only one end...” in General Warning, Section 10, Page 10-1. See following NOTE. NOTE: The key switch should be placed in the OFF position and left in the OFF position for the duration of this test. 2. With the batteries connected, place Tow/Run switch in RUN. Using a multimeter set to 200 volts DC, place red (+) probe on battery no. 1 positive post and place black (–) probe (with insulation-piercing probe) on the purple/white wire (1) at a point close to the three-pin connector at the MCOR (Figure 11-11). The reading should be approximately 48-50 volts (full battery voltage). Figure 11-11 Test MCOR: Purple/White Wire (+) ELECTRICAL SYSTEM AND TESTING Troubleshooting 2008 IQ Plus Electric Vehicle Maintenance and Service Supplement Page 11-19 11 3. If reading is zero volts, check the purple/white wire continuity from the three-pin connector at the MCOR to the 24-pin connector at the speed controller. Check terminal positions in three-pin connector at the MCOR and the 24-pin connector. If all of the continuity readings are correct and the connectors are wired correctly, replace the speed controller. 4. With multimeter set to 20 volts DC, place the black (–) probe on battery no. 8 negative post and the red (+) probe (with insulation-piercing probe) on the white wire (2) at a point close to the three-pin connector at the MCOR (Figure 11-12). The reading should be approximately 4.65 volts. 5. If reading is zero volts, check the white wire continuity from the three-pin connector at the MCOR to the 24-pin connector at the speed controller. Check terminal positions in three-pin connector at the MCOR and the 24-pin connector. If all of the continuity readings are correct and the connectors are wired correctly, replace the speed controller. 6. With multimeter set to 20 volts DC, place the black (–) probe on battery no. 8 negative post and the red (+) probe (with insulation-piercing probe) on the yellow wire (3) at a point close to three-pin connector at the MCOR (Figure 11-13). The reading should be approximately 0.32 volts with the pedal up. Slowly press the accelerator pedal and note the readings on the multimeter. As the pedal is pressed, the reading should increase until it reaches 4.65 volts when the pedal is fully pressed. 7. If reading does not increase as the pedal is pressed, replace the MCOR. 8. If the reading is not approximately 4.60 volts with the pedal fully pressed, the vehicle will not operate at rated top speed. Check the MCOR resistance. 8.1. Disconnect the battery cables as instructed. See WARNING “To avoid unintentionally start- Figure 11-12 Test MCOR: White Wire (+) Figure 11-13 Test MCOR: Yellow Wire (+) Passenger Side Frame Rail 3 ELECTRICAL SYSTEM AND TESTING Troubleshooting Page 11-20 2008 IQ Plus Electric Vehicle Maintenance and Service Supplement 11 ing...” in General Warning, Section 10, Page 10-1. 8.2. Disconnect the 24-pin connector at the speed controller. 8.3. Set a multimeter to 20k ohms. Connect the red (+) probe of the multimeter to the yellow wire at the MCOR three-pin connector with an insulation piercing probe. Connect black (–) probe to the purple/ white wire with an insulation-piercing probe. 8.4. With the accelerator pedal fully up (not pressed), the multimeter should read approximately 1k ohms. 8.5. Slowly press the accelerator pedal while monitoring the multimeter. The resistance should rise as the pedal is pressed. When the pedal is all the way to the floor, the multimeter should indicate between 5.67k ohms and 7.43k ohms. 8.6. Using a multimeter set for 20k ohms, connect the red (+) probe of the multimeter to the yellow wire at the MCOR three-pin connector with an insulation piercing probe. Connect black (–) probe to the white wire with an insulation-piercing probe. 8.7. With the accelerator pedal fully up (not pressed), the multimeter should indicate between 5.67k ohms and 7.43k ohms. 8.8. Slowly press the accelerator pedal while monitoring the multimeter. The resistance should drop as the pedal is pressed. When the pedal is all the way to the floor, the multimeter should indicate approximately 1k ohms. 8.9. If the MCOR does not operate as described, replace the MCOR. |

Re: 01 club car regen wont move
This is what ive been looking for. I dont know if it has the MCOR throttle or not. If it does and one of the switches in it are bad would the solenoid still be clicking? And thanks for the info. This thing is kicking my butt lol.

Re: 01 club car regen wont move
Most likely not, but I have seen them where the Throttle input from the MCOR has gone bad, so all the switches work, solenoid works, but the controller get's no signal to the throttle input because the MCOR potentiometer is bad. The MCOR is a small black box under the right hand Frame rail where the passengers feet are. See the pics

Re: 01 club car regen wont move
FYI . . MCOR's are not repairable . . expendable part . . .

Re: 01 club car regen wont move
I got it fugured out. I pulled the wiring connector off the mcor and when I unplugged it and let the wires hang they just fell to the ground. All the wires got cut or broke somehow. Thank you for all the help guys. I really appreciate it. Oh and one more thing. When I first started working on it I checked the key switch with the volt meter. I took the wires off of and checked the contineuty on it and it showed no contieuty with the key on and off. But the key switch works. Kinda wondering how thats possible. Thanks again for alll the help.

Re: 01 club car regen wont move
I didnt have it in ohms. I had it on the contineuty mode. I tested it SEVERAL times. I set my volt meter to the contineuty mode took the wires off the key switch and then put one probe on each of the posts(theres only 2 posts on the key switch). My meter will beep if there is contineuty. I touch the probes together before i test something to make sure the meters working right. I put the probes on the posts and no beep BUT the cart still runs. Its magic. Lol na I probably did something wrong. My mind was already blown by the time i started checking the key switch.
