Thanks I will look for the wire tomorrow. I am like you I am just trying to think of things. I spent part of the afternoon checking wires to the alternator and cleaning the grease off the starter. I found the big ground wire on the starter.

 

Big ground wire to the starter? You mean the ground wire from the rad cradle to the transmission housing?


#3 is the ground stud

 

No that is not the one I was thinking about. I will look tomorrow morning and verify. I will report back. Thanks again.

 

I'm back. While I had the HHR up on blocks looking for the electrical gremlins I figured I might as well change the front wheel bearings and hubs. They had 181,000 miles on them and were ready to be replaced. I found MOOG bearings and Hubs at AutoZone and decided to get them. They have a 3 year warranty, better than anything else I found. They went on pretty easy, no real problem getting the old hubs off. I love living in North Carolina and no salt or rust.

So I have the HHR back on the road now to drive it and see if and when the electrical issues reappear. I took it out this afternoon for a drive to check out the new bearings and everything was good. I am going to drive it until the symptoms come back, it could be a day, a week or months. I just wanted to let everyone know I will report back. I have the interior panels off, that cover the fuse box on the side of the transmission, and the covers off in the back so I can get to the battery quickly. I have my volt meter and OBD scan gauge in the passenger seat so I can check things when it happens. Thanks for all of the suggestions. I will report back, I know how frustrating it is when a thread ends and original poster never lets anyone know what they found.

 

We still don't know what you mean by big ground wire on the starter. There is no ground wire on the starter. Please do not attempt to ground any wire on the starter, risk of injury or death.

The transmission is not behind the interior fuse block(BCM).

 

ok I guess I meant to say beside the shifter on the passenger side. I am not going to hook up any ground to the starter. I guess the large braided wire is something else. I am just waiting for it to act up again. I can’t really find anything while it is running well.
