Re: Motor testing
Ha, here we are again. You need to have the center shaft supported if you want to spin it. Only other options are to Ohm out the individual coils. Johnnie please help here. This is over my head.

Re: Motor testing
The motor does not have a front bearing, so don't try to spin test it unless it is mounted to the differential.
Also, even if mounted, don't use more than 12V. Mark all four cables so you get them back on the same terminals. Use two wrenches to remove cables. Second wrench goes on the lower nut to keep the stud from turning. Jack rear wheels of cart off ground and put cart on jack stands. Jumper A1 to S1 Connect jumper cable from A2 to positive post on 12V battery. Momentarily touch jumper cable from S2 to negative post on 12V battery. ----------- However, it is easier and less dangerous to check the controller. Connect a DVM between the B- and M- terminals on controller. Key ON F/R in either F or R Press Throttle Pedal until solenoid clicks. If solenoid doesn't click, we need to troubleshoot the solenoid activation circuit before proceeding. If it does click, the voltage between B- and M- should be full battery pack voltage. (Pack voltage should be above 37.5V for troubleshooting) If you have the full pack voltage there, slowly press throttle to floor. Voltage should smoothly decrease to Zero. If not, check ITS (Throttle) input to controller. If it is good, controller is bad. |

It was only a matter of time before the guru stepped in. He gives me that warm fuzzy feeling inside when he speaks.
