What is your education? Have to know?

 

On the HHR, very little.
In the USAF I was a lifer weapons control system tech (Radar, Weapons release computer, lead computing optical sight and missile firing circuits) on the old F4-D Phantoms, then I built automated controls for production machines up til recently.
I know my way around an electron, if that's what you mean. But I am getting rusty fast.

 

WOW! With your education I can see why you think too much about a problem. Relax, look at what's in front of you. Basic's.

 

I enjoy the torture. I have logiced out problems and fixed them without doing much more than thinking it through. This little car is of the new breed of electronic robocars that I'm still not totally comfortable with, however.
All ideas and suggestions are welcome here.

 

My gut feeling is to get a real wiring diagram of the car. I think from there you can answer a lot of questions yourself.
Maybe Don ( Moderator) can help you with this.

 

Don (he's great!) has helped me out a lot, but those diagrams don't tell you everything, such as the normal quiescent current draw we should be seeing. When I checked mine I believe it was 85ma constant, with spikes to 1.7 amps at times.
(Like when you first reconnect the battery cable).
I pulled the XMsirius fuse, the interior lighting fuse, then put a jumper wire from the battery to the lead, then connect the meter from the battery to the lead, let the system quiet down, remove the jumper and could then see its actual draw. I think it was a tad high, but no data is available I could find.
If it becomes a problem I will put some more time into it.

 

Why the "ma" thing? You had a start problem and now you don't. Use the car and see if the problem happens again.

 

85 milliamps, just less than 1/10 ampere. I'm not the one with a start problem, I just saw the same dip as the OP. My car starts like a new one, every time.
(Knock on wood)

 

My mistake, forgive me. Yes I can be an A** at times.

 

You seem ok to me. I ain't mad er nuthin.
