How Do You Jump Test a SEPEX Motor?

[ACEGOLFCARTGUY]

I'm doing another project and want to make sure I pick a working motor to use. How do you check a SEPEX motor using a 12 volt battery to jump test? I am able to make a series motor spin by connecting A1 to S1 together and attach jumper leads to A2, S2. The two SEPEX motors in question, however, will not spin when I do this. I know for sure one of the motors was working in my golf cart. I just mixed up the two and don't remember which is the good one.

Testing a SepEx, Regen, Shunt Motor:

To bench test a SepEx, shunt wound regen motor you jump the S1 to A1 and the S2 to A2 terminals. This is two separate connections. Take 12V positive and hook to the S1/A1 combination and 12V negative goes to the S2/A2 combination. The motor should spin.

Do not run the motor with the front of the shaft unsupported.

Thanks HRC. Hmmm...I can't get either of the SEPEX motors to spin. The series motor does though,

They should run if they're good. Make sure your connections are good on the jumpers...

See I pulled the controller out of the cart thinking it was bad. Maybe the problem is with the motor.

 

[HotRodCarts]

Could be. If you jump S1 to A1 and S2 to A2 on a sepex motor it should run when you connect 12 volts to the jumped connections...

HRC, I got it going. Thanks!

 

[HotRodCarts]

What was the problem?

 

[ACEGOLFCARTGUY]

Wish I knew what it was. I wired the new controller in and thought, ah heck why not, so I tried it and the cart runs!

Hmmm, I don't know why the motor didn't run when you tested it. Glad to hear you got it running...
