Does the Shop ever not charge for switching out components that were really OK on the way to find the real problem. And why is it always $1000 with Porsche’s. Must be a target price... Never give back the money!!!
So the +12V test point was the #1 of 9 on Aux fuse panel. Good catch.
And don't forget to check those multi-red +12V wire connection at Battery like Socal Said before digging for the Ground wire on fuse panel.
Socal must be the most dedicated helper on the net. I'm nominating you for a Nobel Piece Prize.
OK Gotta go hit a club for New Years so happy happy all.
