Here's what you do. You have to have into the cart!
I know I got your hopes up for nothing!!
For a DCS/PDS:
1. make sure that you have 14v in on the white wire.
2. with a v meter check the black (out wire) when the solenoid engages you should have .9v, and whith the pedal all the way down you should reach 2.9v.
For a series:
1. make sure that you have 14v in on the black wire.
2. with a v meter check the white (out wire) when the solenoid engages you should have .5, and whith the pedal all the way down you should reach 1.5v.
Thats the only way you can test it. Sorry I was thinking of testing the coil with an ohm meter.
