Here's mine for comparison (sea level)

2012 S85 w/2017 rev q motor and qc charge coolant bypass

Where's my midgate? 😃 The Silverado is looking better every day, not to mention it's roughly the same cost!

That solves for a bigger problem but misses the root cause. In my case, I did as you suggested but to my surprise, no coolant drained from my inverter drain. Only after dropping the ldu and pulling the stator cover did I see that my windings were bathing in an inch of liquid. My inverter is...

Thanks @asavage for some tips that helped and also kept my attitude positive. Even though my stator windings were irreparable, my salvage ldu is in good shape. Just finished installing the qc bypass to keep it that way. Car drives like new! My inverter and gear box are still good, in case...

I am right there with you. Part of me is waiting for "cbt v2" with all the lessons learned fixed... somehow I think this run of "trucks" is one and done. Tesla will either double down or abandon this experiment.

This thread brings back nostalgia from back in the day... does this car have halogen headlights by chance?

So.. just bought a salvage reman Rev q ldu to replace my utterly damaged non reman Rev q ldu. The reman one is clean , but I noticed this one had a hole in the speed sensor area where the non reman Rev q does not. What's that all about?

So do you have two passes, or do you discard one of them?

Good luck! I dropped the whole motor before performing the coolant delete and pulled it apart and a surprising amount of brown mucky liquid drained out. 😥

Thanks again, was able to follow your suggestion and managed to test the resistance. Inverter Checks out fine, but the stator - oh boy is that shot. Pulled it apart and it was flooded :(

Thanks for the tip - I'll give that a go since what you did is exactly what I am tying to accomplish - test the stator resistance while disconnected from the inverter.

Sadly, I'm all too familiar with the HVIL loop diagrams :) But I do thank you for the hope on the stator windings - If it were crystalized coolant, I'd expect to see some resistance, I'm registering a dead short (less than 2 ohms yikes!). [using AMPROBE AMB-25 Mega-ohmeter set to 500V] But...

Incredibly stupid question - in the middle of a rebuild due to HVIL fault on a Rev Q Unit installed by Tesla. Thought I found my culprit - as I had low impedance between ground and B+ on the input lead (~400Kohm vs > 2Mohm). Replaced the B+/B- harness and impedance checks out. No sign of...

What is this part? Custom made? 3d printable?
