Sorry, I just got home from work
Here’s a video https://youtube.com/shorts/dTe92MWjiTg?si=mhxHFlLFQUD-JGkU
Good morning, yes its on. When its off the panel turns off
Check those two studs on the PSDM again. Or follow that cable on the left around to where it goes. You need to have power on those two studs.
Something is not hooked up correctly.
Who has been messing with the wires on this car? If you, can you explain the intent?
So I tried a different volt meter and I’m getting 71 V on the B positive and B minus
Now that you introduced another meter into the equation, you need to start over.
Measure PackV at the battery, then move up to the PSDM and check it there. PackV should be the same. Compared to your last vid it looks like you lost 4v between the front and back?
Then KeyON and check it up at the POS and NEG on top of the controller. It will be a volt or two lower at this point.
Now, Go back up two posts to where I wanted you to test what you see at the Main Relay.
Pay attention class. Don’t skip over important tests. Otherwise, I am simply wasting my time here.
Oh, and try and treat your test equipment with a little more care and respect. Ripping an alligator test lead off by it’s wires might be why your last meter is no longer working. That was pretty brutal.
Hey, I’m completely very appreciative and very thankful you guys are helping me trying to help me with this. I paid $10,000 for this car and I physically gutted it out all the plastic and then I made all these plates to go around it to make my job easier at work. I welded the frame and everything but electronics is not my thing. and I had the car for 6 years I think. And then spent the extra two grand on the new batteries because the old batteries went bad and it was the same price as the lithium battery.
I mean, I’m happy to pay you for your time. I don’t want you to waste your time. I just need to get this resolved.
My number 386-627-9090 if you want to facetime
Here is a video so I’m getting 72.9 V at the battery and at a B+ and b-
this cart made my life so much easier and my coworkers job so much easier you have no idea
→ KeyON and check it up at the POS and NEG on top of the controller. It may be a volt or two lower than PackV at this moment.
What do you see?
=====
→ Locate your Main Contactor. It has big orange cables going to it, and two smaller 18ga wires that control it. One is probably Orange, the other is Black/pur (iirc).
This thing:
Note: the following two tests need to be done with your Black meter probe on the NEG post on top of the controller. This is your reference.
→ Measure what is on the small Orange wire (ref B- on controller)
You should see PackV. → Verify (Y/N?)
→ If Y, then Measure what is on the other small wire ( Bk/pur wire (ref B- on controller)
You should see PackV minus a couple volts. → Verify (Y/N?)
So with the controller on, I’m getting 71.9 V ; on b+ and b-
at the battery I’m getting the 72.9v with this Harbor Freight voltmeter.
Here’s some photos with a better quality if you need to point something out
I’m not quite sure what the problem is here…
In an effort to speed diagnostics up, I frequently give more than one task in a post, or several different directions for you to go if they are related.
You seem to be only doing one test per post, and ignoring everything else in that request. I tried to point this out several times(that you are skipping steps), and you even ignore that!!!
I have tried to direct you back up to a test sequence so I don’t have to retype the sequence again,
→ Ignored
I just went back up and cut out previously ignored instructions and pasted them in again, and you ignored them again. I even cut out pictures to direct you to the item I wanted you to test/inspect.
→ ignored
Pay attention or I am going to class you as a troll for wasting my time.
-I’m sorry I asked on the video. But the only other place where there’s a positive and negative is behind the breaker box and this gray box.
-the negative on the volt meter I went on the negative on this gray box and then I touched the orange wire the small little orange wire and I’m getting 71.9 V
It only lets me post one image per post on this form
The small black wire next to the small orange wire I’m getting no voltage when I go on the B-
What is Packv?
I get zero voltage when I touch the black/Purple wire to the b-
I removed the 23 pin and it did not do nothing on this controller. I had to scroll up and reread all the instructions. Sorry, just overwhelming it just so complicated.
Sorry, just overwhelming it just so complicated.
Just follow the steps I am directing you and you should be fine. If you skip what I am asking and instead hop around you won’t get anywhere.

PackV → is Battery Pack Voltage. I had you start there to get a baseline of what should be see elsewhere in your tests.

I don’t know what is the controller
the only other place where there’s a positive and negative is behind the breaker box and this gray box.
Exactly. The motor controller IS the grey box.
When I call out for a voltage test on a wire, I will (usually) call out it’s REFERENCE. That is where your OTHER meter probe should go. I will usually pick out the closest location to place that probe.

Perfect- Good test. (now to part 2 of this test)
The small black wire next to the small orange wire I’m getting no voltage when I go on the B-
(and I think you duplicated this test here)
I get zero voltage when I touch the black/Purple wire to the b-
On this component (which is called the Main Contactor Relay)
AhHAAA!!!
This might be the cause of your -64.
At this time there should be voltage on BOTH wires(ref B- or NEG on the controller. )
See if this just a bad/dirty connection.
→ Pull off the orange spade connector and put it back on. Do the same for the Black wire.
Do the voltage check again.
I believe the other set of spade connections on the other side of the coil are duplicates. The results should be the same as if you are checking the wires, connectors themselves.
Follow?
This test is meant to be done with the wires still attached to the relay.
Did you try the other flag terminals on that relay?
Directly across from the orange wire is an identical set of connection points. Do you get the same readings?
