Here are a bunch of options:

Started working on my doors - something I have been putting off for a long time. They are in really bad shape and I may need to look for a better set somewhere.

The hinges are frozen solid onto the doors with Phillips screws. I had to go all Scarface on them and 'say hello to my little friend' :D ...

@HerbP, the LS600H bellhousing is a completely different shape than the GS450H

Finally got shifting working - turns out I did not have SL1+ and SL2+ wired up to 12V+. Wow this thing can accelerate in low speed! And with zombie release 2.30 it's really smooth compared to before. Hats off to the developers for getting zombie to where it is, truly amazing.

Now I'm running out ...

Fixed the oil pump noise with a new set of tires

I haven't changed out my oil pump bearings, and it's really noisy, so decided it is time. I have a spare transmission, so started changing out its pump bearings in order to do a quick rotor swap over onto the Scout:

That pump was clearly in better condition than the Scout ...

Getting close to finishing my rear bench seat battery pack a.k.a. 'the electric chair'. Added mid pack fuse and contactor, and was able to cut down and reuse bus-bar material from the original pack

Back on the Scout, I've been working on final welding and fitting of the roll ...

Making progress on the rear bench pack. Lots of wiring, slow going for me. All 8 bmb's now reporting correct voltages. I have a couple of thermistors reading temperature for now, will use the original Bolt temperature sensors which slide deep into the modules. I checked, and ...

Contactor from Sbox likely wont survive quite a low current rating. Also check the coil spec to see if it needs an external economizer.


Yes, clearly I haven't put enough thought into this yet. I looked up the specs, and it does look too wimpy, and is not economized internally so I'll pass on it ...

Also working my new battery pack side project. Rear pack bench seat will have 2 x 6.7kWh and 2 x 5.3kWh modules. Hoping to use these parts I have lying around - contactor and fuse from BMW s-box

Upgraded Zombie to 2.30 over the weekend. It's fantastic! Huge thanks to all the developers. It's night and day to where it was. I suspect my AWD drivetrain with no guibo cushioning must be one of the harshest setups around, and it is really smooth now. Still need some dialing in of parameters, it's ...

Received my golf cart bench seat, so had to do a rough test fit I could lower by 2-3 inches by cutting out the floor and dropping it to the frame rails, but that's not in the plan for now.

After more messing around, I got it to work. Turns out I have a couple of BMB's that are not happy wired in a 4S config, the other 18 BMB's work great. I tested the two offending boards multiple times with 4S, 5S and 6S packs. Perhaps a tolerance issue, or maybe my sketchy ESD protocol had a play in ...

This is a stock image of the original seat
Here is where I'm at:

Yes, batteries will be fully enclosed in boxes. For the rear bench seat battery box, I'm going to try and mimic the basic design of the original bench seat (that I don't have), except it will sit higher. I'm undecided whether to have it front facing (as per original) or mounted further forward and ...

Title changed - thanks, I see that was confusing.

I'll try resoldering today and see if I can get the readings to behave.

On a related note the blue connectors were hard to source and looks like only comes in a header style configuration. I'm wondering if I can change out the pins for a wire ...

I'm planning to use tesla s bmb's and simpbms with my Chevy Bolt pack. It's 96 S with 8x10S and 2×8s modules. Each module will need 2 bmb's.

I am doing a test with a 9s pack from a hoverboard pack to understand cell wiring. This way I can simulate wiring for one half of the 10s module and one half ...

For BMS, the plan is to use salvaged tesla slave bmb's. Picked up 20 cheap on ebay @$9ea

[attachment=0]20250821_133930.jpg[/attachment

I bought the 2023 Bolt pack a while ago as it was local and seemed too good to pass up. It has 8 10S modules and 2 8S modules.I got a leg up from a forum member here with CAD of custom module endcaps to make mounting easier. Plan is for 6×10S modules up front, and 2×10s+2×8s under rear seat. This ...

Lots happening over the summer, but doesn't seem like much has changed on the Scout. However.... my BMS has taken a dive and after troubleshooting and going through the various stages of grief, I have come to the conclusion that the cell taps on my modules are likely coming loose (I repaired 2 of ...

Looking at a picture in the OSTI report, I can see that yellow LV wire shielding crossing over the path of where my brass inverter post connects. Looks like I will need to tear in and see if there is enough slack in the cables to tie them out of the way

are you saying if the isa shunt is connected you get 15mega or just inverter?


I need both ISA HV sense wire and inverter positive lead connected to complete the circuit.

I think I'm getting somewhere:

I'm using the LS600H inverter, where I tap into the bus bars is different than on GS450H ...

Yes, live, by that I mean I have HV inside my HVJB, but contactors open. Here is a picture, showing where I took the positive reading on the megaohm meter. Negative was to chassis ground.
HVJB.jpg

If I unplug the HV connector on left side, I get 1500MΩ reading. That cable runs directly to the ...

Thanks for the reply. From the Megger, with inverter connected I get 15MΩ between HV positive and chassis, & 6MΩ between negative and chassis. Tested at 500V.
HV neg to chassis ground.jpg
HV positive to chassis ground.jpg

With inverter disconnected, battery only, I get around 1500MΩ from either ...

I've been trying to figure out why my VeroBMS (SimpBMS) is throwing errors and not showing correct cell count. I'm suspecting bad slave boards, more to come on this as it may or not be related to the below.

I have a B250e pack with 7S Tesla modules. Car runs, drives and charges and currently sits ...
