It was on the one in the car now
Pin 15 12.3 volts pin 3 zero
I have managed to break the carefully rule. I thought I had a good set up but managed to short my alagater clip. This put the emergency switch on and i can’t reset it.
On the battery
Failure to send
We should listen to Byron.
Were does that leave me?
I don’t know. What did you damage?
I don’t know app is showing full voltage.
Maybe Byron understands what that means.
I haven’t looked at the Think manual yet.
It sounds like you tripped the BMS. DisMos probably off.
Show us a screenshot of your app.
Shut off the key of the car before you try to restart the DisMos.
You may need to shut down the app on your phone and restart, reconnect, and try again.

I’m good to go on my end.
I’m going to send one of my clusters back to the cluster guy in Florida. I don’t see a smoking gun in these two clusters but I want to make sure. The one cluster I have here was just done by him back in November. The other cluster was also touched by him in 2015.
I’m good to go on my end.
??? What does this mean? The car is fixed?
I’m going to send one of my clusters back to the cluster guy in Florida.
What make you think this? Have you talked to Bob?
No car is not fixed. The battery issue is fixed. I had to reset the BMS
I am at a loss on this car. I want to do everything I can do to get past these issues. For the first two weeks I had hope that the fix was right around the corner. Now I am getting desperate after the third week of dead ends. Figured I would send out one Cluster again and one controller for confirmation that everything is ok.
Please keep guiding me if you have any Ideas forward.
What in that circuit is linked to the serial communication port? why is everything overvoltage until I plug that broken serial adapter in?
Both of my controllers act exactly the same hooked up to the original cluster to this car.
The second Cluster acts a little different but close.
No, I haven’t talked to the Bob the Cluster Guy with him since he told me it can’t be done. I am learning, but I can’t speak intelligently enough about the process to ask the right questions.
Thanks again for your support and time you have given me-My problems have got to be wearing on you two-I am worn out from my own stupidity.
I’m posting this question.
The cluster guy adds a separate voltage converter to the Clusters he rebuilds. It’s only a three wire plug.my other voltage converters all have four wire plugs. Ground return on both the 72 volt and 12 volt sides.
With his ground Return being only on one side.
Maybe we are missing the correct ground reference?
Somehow to the serial device terminates the ground signal?

Interesting. Start there. Measure it’s output.
So much for not mixing grounds. This 12 is probably not making its way out of the cluster.
Also- what are you using for a meter?
It’s outputting 12.6 volts or so.
I have a couple different meters here. Both have been checked to a fluke I have at work.
It’s not the out put here I was thinking about it was more like where inside the cluster are checks being made?
There is serial communication to and from the controller. My brain started chunking about checking voltages using B- vs. pin 16
Then I was looking at the 72 to 12 converters on the car and both have ground return on both sides.
The Thinks that I have seen have two Sevcon DC/DC (may have replaced the factory) converters in the front bumper area, mounted back to back with a firewall in-between.
