The M- terminal on a stock PDS controller (Curtis 1206MX) is labeled A1.

0 is good you are looking for less than .4 ohms

He stated he had a '94 model Medalist, Series.....if its got a PDS controller on it, it ain't gonna run, is it?!

You are both right and wrong.
What you said is technically correct, but my reply was not to kingcobra,the OP with the 1994 Medalist Series cart, it was to the thread hijacker, eejay001, who listed the terminals on a PDS controller.

It is best to start troubleshooting (or a drive) with a fully charged battery pack. (38.2V)

A 94 Medalist could have either a Series drive or a DCS drive, which do you have?
(If there is a Run/Tow switch on controller cover, it is a DCS)

The phrase: "at first 2 posts on controller" is relative to the the position a person is viewing from. The posts are labeled B+, B- and M- and depending on type controller, there could be one labeled A2 as well as a pair of smaller posts labeled F1 & F2.

If the solenoid does not click when throttle pedal is pushed, troubleshoot the solenoid activation circuit.
If the solenoid clicks when pedal is pushed, you should have full battery pack voltage on both main terminals of solenoid.
If you do, attach DVM test leads to B- and M- posts on controller.
When pedal is pushed just far enough for solenoid to click, you should read full pack voltage.
If you don't, you have a open somewhere in the high current circuit.
If you do, slowly press pedal to floor. (Be sure to have rear wheels off ground while doing this, or cart might run over someone or something.)
As pedal is pressed to floor, the voltage should decrease to near zero.
If not, either controller or ITS circuit is bad.

Good luck.
I get a reading of about 26 v on the controller side of the solenoid when the solenoid is not activated. When I activate the solenoid by pressing the accelerator I get full 38.4 v. Test lead on B- and M-....accelerator slowly to the floor.....no change in voltage....38.4 V. Bad controller? Why do I get the 26 v with the solenoid not activated? Connections removed from the large lugs on the solenoid I get 0.04 ohms reading across the lugs. Bad resistor?

It would probable be best to start a new thread rather than hijacking a three year old one that has already been highjacked.

The voltage between B- and M- not decreasing towards Zero as pedal is pushed towards floor could be a bad throttle input to the controller, or a bad controller.

The 26V is lower than expected. Should be pack voltage less about 5V.
The pre-charge resistor for a 36V system is typically in the 200Ω to 250Ω range and either 5W or 10W.

The resistor probably isn't bad. And will not prevent the voltage between B- and M- from varying when pedal is pushed.
