Weird Electrical Problem / Drainage

[njshore4x4]

A bad regulator would eventually drain the battery dead and the low voltage would cause the car to run funny and eventually die completely. It started funny this morning and I was able to drive 60 miles to work. Then leaving work it started again like it had a weak battery and I drove 60 miles home. Also if the regulator was bad, when I disconnected the negative battery cable, the car would just die or start spurting but it stayed running. I wonder if my starter is starting to go bad. I really need to get to my shop to get my multimeter!!!!

If the battery has a charge, the car will run without a perfect alternator for a while. Check voltage at battery when running. If discharging....Starter does not sound like an issue if the car starts with a jump.

HERES THE LATEST.

voltmeter doesn't lie.

Car off, battery voltage = 9V
Crank a few times, no start, battery voltage = 3-5 V
Car running at idle voltmeter = 13.6-13.9 V

conclusion = dead battery.

Thanks everyone for some good ideas!! ron

I'd believe you can check with your OBC as well, the running voltage among other things

how do you use the OBC?
