Can anyone tell me how to test my ride for fun 2002 GEM cart, the motor is a separately excited (or “sepex”) motor I have replaced the bushes and installed the motor on the cart… The motor passes the continuity test. I would like to apply 12 V to the motor to see if it runs. I believe that I have other issues like maybe a **bad controller cause the cart still will not run**. So, before I send the controller out to get checked/rebuilt I would like to know that motor runs with the new brushes. So, my question is where do I apply 12V to the motor for test purpose? I understand that these motors are a separately excited motor and applying power for test purposes may be different then a series or parallel motor. Thanks MB ---

I’ve done a search and cannot find any information on how to test a separately excited motor on applying power for test purposes on a ride for fun motor… ---

you would need a DC voltage for the field then you can start applying voltage to the armature. ---

You are safe applying 12v direct to field and armature to see if motor spins. Parallel connect F and A. ---

After 2 mos of poking around and determining that your car is horribly mis-wired and is in no condition to work properly as it is, As well as your controller is most likely suspect/damaged from being submitted to being brutally bypassed, You are _ **STILL** _ stuck on this? **Other topic/threads** Aug 25 → [[2002 gem cart will not run](http://community.electricforum.com/t/2002-gem-cart-will-not-run/29622)] Oct 3 → [[2002 gem cart ride for fun motor](https://community.electricforum.com/t/2002-gem-cart-ride-for-fun-motor/29773)] I really am not sure what you are trying to prove by doing this. But OK. Connect +12v to both A1 and F1 Connect -12v to both A2 and F2 -or- Connect A1 to F1 with a short cable. Apply +12v to A2 Apply -12v to F2 Prepare for sparks and violence. ---

I spent the time and money in replacing the brushes and just wanted to justify moving forward with repairing/replacing the controller and repairing the wiring mess I have. The motor works! Thank you, Sir, for staying with me… MB (I have a problem with giving up to easy)
