This has been an on going problem in my e34, we have only done the double jump process one time, it seems thats the only way she`ll turn over.
The battery is Brand new, we got it tested last week just to make sure.
When I double jumped my car and got it idling it worked great! unplugged everything and went for a 20 minute stroll,had a little fun up in the curvy hills of washington state so on and so forth.
I get back home and pull in the drive way and shut off my car, I waited for 30 seconds and tryed starting my car up and it acted like I had a dead battery!!!
It turned over 2 times following the clicking sound of the solenoid!!!
It has been 2 days now and I dont even have enough juice to unlock my electronic doors
Any and all help is appriciated.
