FICM Removal

Should one or both batteries be disconnected when removing it. If only one, which one? Thanks.

You should disconnect BOTH batteries, and leave them disconnected until AFTER you re-install the FICM.

I guess safety first dictates that you disconnect the batteries. Must admit that I didn't, and I've had that thing out of there 3 or 4 times. The connectors are so well shielded that I can't imagine how you could short it out.

If you're going to disconnect them, there is no point in only doing one. You have to do both or you haven't cut the power.

My connectors came off fairly easy wouldn't think they would be that bad to put back in. So a little dielectric grease is a good idea. Sounds like a plan. Thanks guys.

I never disconnected mine when R&R the FICM. Thinking back I guess I should have.

That!
Plus what purpose (besides not removing one more cable) does only removing one serve?

On the flip side drop a wrench down onto the live cables and you are in need of new shorts at a minimum.

The only Other hard part is the Degus bracket ( I lost hide), just move the degus out of the way put some rubber close offs or caps on the hose and watch the bracket,the back bolt was apita make sure the rubber gromits are back on for shock movement(vibration).
