No voltage at controller

disland · 03-02-2019, 09:23 AM

'98 Club Car DS, Key on, FNR in forward.

Testing voltage on controller between M- and B-

Not getting any static voltage

Depressed pedal until solenoid closes and I am getting exactly 1.8V

I put in a new controller and am getting the same result

Any ideas welcome

Alltrax controller status light solid green manual says that means Controller ready to run

Does the solenoid click when you try to go?
If yes there should pack voltage between M- and B-
Check your throttle signal.

I tested the solonoid and its fine. I am not getting pack voltage between M- and B-

I tested the throttle signal and it goes form 0 to -3.75 volts. Is that enough or do I have a bad potentiometer?

The solenoid should click and the controller power up about the same time. SO see why your solenoid is not getting activation signal and yeah the throttle signal should be 0-5k so maybe a bad pot, try adjusting it?
Does the controller give the 0-5k blink code when powered up? It should.

Yes, The controller powers up immediately with solenoid engagement.

But interesting. This time I got 3 green 1 red which means "uncalibrated throttle"

Use your Alltrax Tool Kit to relearn the throttle. (Verify it to be correct first)

Tried it 5 min later, now getting the 0-5k throttle one green flash then solid green

disland · 03-02-2019, 05:06 PM

Tried again, one green flash then solid green Still only 1.8V across M- and B-

Hook your PC up to the Controller and open the Tool Kit and check this Monitor Screen.
