After replacing the battery I'm still having troubles.
In May the car randomly shut off on me after coming down the rough mountain (~1 hour drive.) This happened while moving but fortunately I had a place to pull off. I waited a minute and it started back up.
Fine for weeks. Then it happened again while moving, pulled off into a Barnes and Noble. Waited, started back up and drove fine for hours the rest of the day. Fine for weeks.
Then about 3 weeks ago, sitting at Sonic for about ~30 minutes I had a dead battery. Friend came and jumped me off. Put it on the trickle charge. Ran fine for a week. Was an hour away from home, car wouldn't start. Lights were dimming, Mercedes kindly jumped me off.
Replaced the battery from NAPA. $175. Next day, wouldn't start. Touched the battery charger to it and started. Ran fine for days.
Again, shut off on me going down the road.
Took it to Advance to check the battery/alternator etc. The printout gave the following results:
Charging System Test:
Now I know with the drain test the car might not be totally asleep yet, but isn't 12.03A a little high?
So I'm trying to find out what's draining the battery. Using my little voltmeter, the grounds all seem to be good. But I'm wondering what could cause it to drain so bad that it would cut off while going down the road.
While playing with the voltmeter I did find that it had a pull on it after ~15 minutes. I don't remember how much but it was enough to make me go "whaaat?"
My "car expert" friends are kind of stumped. One says starter because it completes a circuit and if it's messed up it could cause all those problems (not smart enough to know quite what he's talking about.) Another says it can't be starter because it does it while going down the road and it must be alternator.
Any advice is greatly appreciated. I don't want to the dealer$hip without a definite problem.
