Based on what Mark did and other pieces of information I could find on this forum, I decided to clean my PEM. Enjoy and use at own risk......
I would rate this difficulty: 5/10. It's just following a procedure and making sure you don't drop any nuts
Mod Note: One of our other members posted a YouTube video on the process, which is a good compliment to this procedure. See Roadster Rear Blower Maintenance - Page 7
An AWESOME thanks for this. I just did it this morning.
After shutting down the power, it took about 10 minutes for the voltage across the BAT +/- terminals to fall to under 2 volts. Must have been a lot of capacitors to bleed off.
On my 2.5 the only difficulty was putting the PEM back in. Aligning it with the brackets that hold it from the left and right sides underneath, and with the 13mm bolts that go into the sides of the battery. That was a bit of manhandling.
And my PEM underside looked clean, and nearly pristine. I was gonna ignore cleaning it, since I had already done the blowers underneath.
But even thought it looked clean, when I took a compressor to it at 80+psi, it blew a lot of dust out. So I'm glad I did blow it out even if it appeared that it didn't need it.
With these instructions and a friend who used to service Hondas (but knows nothing about Tesla's) we got it knocked out is about 2 hours.
Seriously, it's two person job, but it's easy!
