01 E825 NO GO just master click

Car sat for 10 yrs, we got it and replaced all 6 batteries and got it to run. Ran great for about 2 months and NOW it was barely creeping and % of batteries was around 60%. Brought it to shop charged batteries to 95% wouldn’t move in F or R. Noticed the -06 code and tapped on the motor case with hammer and it started to work. Went about 100 yds and it started slowing down to where I didn’t think I was gonna make it back to shop…lol

Pulled motor off and it was pretty clean and brushes were standing up tall, however cleaned everything up and put back together and it will do nothing, no humming like it previously did before I removed motor. Never sped up to fast like it did 3 months ago. Figured I would reach out for advice on this ( maybe pedal ) ( motor )??

What do you mean by “Standing up tall” ?
This sounds like something that I should consult my physician about if condition exists for more than 3 hours.

Brushes should slide freely in their cage/holders.

One indication of stuck brushes would be measuring voltage across the A1 and A2 Cables when pedal pressed, AND seeing residual V slowly go down when PedalUP. (do this test with wheels off the ground so you don’t get run over if car decides to suddenly be on the other side of the garage)

Are there any error codes on the dash display?

Code is -05 but has new batteries in it.

Brushes are at an angle and I mean by standing up tall is they are not worn to a point I would be concerned.

The angle of wear throws me off. Most carts are straight brushes to motor these are laid over about 22 degrees if not more?

Now today NO codes percentage is 65% and i have a video of the test across A1-A2

Highest voltage is 50v, its that way from 3/4 pedal to full kinda like the foot pedal is not sending all the current?

Not necessarily. It’s not what I was looking for.
What does it do when you lift your foot off the pedal?
Does it immediately drop to (near zero).
-or-
does it slowly ramp down over 10 - 20 seconds? (Possibly never going to 0)

6

Goes all over the place while going down to 0.003

7

That could mean a lot of things. Can you expand on this a little?
How quick before it reaches (near zero).

Took a whooe.2-5 seconds

Ah. That is just the design of this motor. Clarify- Did you install new brushes and they are straight cut?

Code is -05 but has new batteries in it.

Now this is more important.
-05 Start switch fails to close.

POSSIBLE CAUSE

Defective start switch circuit.

  • Check start switch to insure closure when accelerator pedal is depressed.
  • Check for open circuit or loose connections in start switch wiring.
  • Check for proper accelerator pot adjustment

Is your pedal coming all the way back up? Are there any rocks/debris under the edge? Possibly the floor mat?

It is possible the pedal switch is having issues

Did not install new brushes as these looked good except for the angle in which you have answered that part.

It clicks loud when releasing parking brake but no click when it don’t run so I’m going to look into the pedal to see if I can find anything

Thanks for the help.

Did you check to see if they were free? Sometimes they get bound up and stick in place. This causes a bad contact and arcing (which is bad).

The V check I had your do indicated this may be the case. (V should have dropped instantly when pedal released). (You reported 2~5 seconds).

This condition is only seen as long as your -05 was not showing on your display. (There appears to be more than one gremlin in your system)

Yes brushes were free in holder I checked and blew compressed air throughout to get what little bit of dust out.

The V drop after letting off pedal drops as wheel starts to slow down.

It’s not as fast as it was a few months ago

I feel there’s more going on and will be checking pedal assembly also

Wait.. hang on a second…
When did this cart decide to move again? In your original post 4 days ago it was doing nothing.

15

Sets overnight and runs again. When I first noticed it I tapped motor with hammer thinking stuck brushes. That’s why I pulled motor to check.

Also when it won’t go there’s a humming noise from motor?

It vould be the opening to a sing along

-05 code…solenoid clicks when you turn it on and all 12v works lights, wiper, etc…when it times out nothing works. You pull parking brake and reverse alarm is on take off parking brake and it starts to fade away. There’s a Gremlin in this cart somewhere…when you put it in reverse there’s no back up alarm unless you set the parking brake?

-05 code…solenoid clicks when you turn it on and all 12v works lights, wiper, etc…

Are you sure the MC/solenoid is closing? or opening? If you are observing ANY wrench codes, (such as the -05) the solenoid will open.

when it times out nothing works.

This sounds like you are observing the Acc circuit timing out? What is changing?

What is not normal is that the Key(being in the ON position) should be holding the Acc circuit ON. Is Dash display still ON?
If no, and Key is still ON, then - Jump the key switch to see if the car (display and Acc) comes on and stays on.

You pull parking brake and reverse alarm is on take off parking brake and it starts to fade away.

Have you been messing with the HandBrake switch and stuck the wires back on the wrong tabs? This is exactly opposite from what should be happening.

Note: BrakeNotSet warning is a steady beep. This is active when KeyOFF and brake off.

Reverse beep is pulsed. This is active when switch is in REV. (I think even when KeyOFF/KeyON?)

Q-> Your original post#1 mentioned that you brought it to shop. Were you referring to YOUR workshop? Or did you take to some other shop for service?
Does it look like they did some creative wiring?

Sold cart after getting it running and they stated it wouldn’t run no more. Im at 73.1v pack and @ fuse …solenoid. Im not sure if they have changed anything or not? As far as parking microswitch. I have a green wire on top, white in middle, and yellow/green on bottom terminals on micro. It’s strange as the cart sat for 10yrs we installed new acid batteries and got it running. Sold it and Now there’s trouble.

So I went back and read your comments. When you turn on the cart and release the P brake the master clicks. Once it clicks again it is sitting pretty much dormant (paused)

When you mash the pedal there is no click at all like it use to be
