I have checked a couple of vendors on the list. But have not found anyone that has brushes.
In a google search. I have spotted a type B brush that looks simular. But nothing connecting it to my "advanced motors and drives"motor
Do you know a part number or size brush i require?
Update…
the red/white wire was disconnected from terminal 6 which supplies power to the ebrake. It now moves but motor is all apart. All brushes were stuck and 3 are cracked.
Thanks…
Now with LFP prismatic batteries installed. 23 cells at 76v. 3.28v/cell.
I get a code 1 Just a continuos plinking of the red light on the charger. No pauses.
I will post video if it will let me
Here is a real update. The one above i wrote weeks ago but i guess i forgot to send it.
I replaced 4 brushes. All 8 were stuck. 4 cracked. And cleaned everything up.
It seems to run well.
Now onto something that has been bothering me from the begining.
The two main cables may have been mixed up at the factory from day one.
Why is the gem battery cable with the black cap going to the negative of the battery pack labeled pack+? I jave had this hooked up to the negative post.
And the cable with the red cap going to the batter positive labeled pack negative?
i purchased it not running.
It now runs after putting in new batteries and replacing some brushes.
WHAT IF…
Would it run or not run or run backwards or blow up if the
two main cables were hooked up backwards?
None of the diagrams i have found shows the labels on the two main cables.
I have been getting what i think is error code “one” on the onboard charger and it wont charge. I havent had time to look into it. Too busy just getting it to move .
I will know more after tracing the two main wires in the morning.
I have never heard or seen this before. I guess it’s possible someone messed up and swapped the two labels/cables on just your car(new guy hired on Wednesday) but I highly doubt it was never caught by someone until now.
It is also possible that some previous mechanic was doing some creative wiring.
Some of the components in your car may have reverse voltage protection built in for such an event, but I highly doubt the car would even come close to working. Since you have already hooked it up this way, check for proper polarity up at the controller. Make sure your meter is set up correctly.
You need to properly identify those cables in the back and that they attach at the proper points in the front under the dash.
I see why you circled those diagrams above. You seem to have conflicting wiring diagrams. Which manuals did you pull those from?
On my 09 car-
The first place B+ attaches is on the Main Contactor and is labeled MC+.
The B- cable should be attached at the TOP connection on the right side of the PSDM and is marked Batt-.
If the main batt cables are swapped at the back, then they are probably swapped under the dash also.
While you are at it, those cable ends could use some cleaning before you reconnect them. They don’t look like they will easily pass 300a.
Can you all check to see if this matches your gems or makes sense…
My gem runs good with it hooked up this way. No fire no smoke
The wire coming of of the negative terminal of the battery has a black cap and is labeled from the factory at that end as “Pack+”
The other end of the same cable is labeled “BAT -” and has a black cap and connects to the BATT- on the front of the PSDM.
From the “Positve +” terminal of the battery. There is a red cap and there it is labeled “Pack-”. The other end of this cable goes to the main contactor and is labeled “MC+” and has a red cap. This same wire goes on to attached to the back of the PSDM. Which i think is the swich on the front of the psdm.
Does anyone have a diagram with actual wire labels?
Are these wires hooked up correctly?
Are the wires labeled corrctly?

In reality, It doesn’t matter how all of ours are marked. You could verify yours in 10 seconds with a meter. Then cut your incorrect tags off and label the cables correctly with a sharpie. Bonus points if you have a label maker.

I checked them with a meter 2 months ago after i took out the old batteries and started to put in the Lithium batteries.
It just is a little nerve racking when you are hooking up a wire labeled “Pack Positive” to the negative terminal of a very powerful battery. and the other end hooks up to an expensive controller.
And a wire labeled pack negative hooks up to the battery positive . and the other end of that wire is labeled MC+
There must be a proper way to label them. But I have not found any wiring schematics that have any labeling on them. So i don’t know what the correct way is.
The only way i think that i have it wired up correctly is that nothing has caught on fire and it moves.
If i have any problems in the future and need some help. It would be convenient that we know we are talking about the same wires and locations.
