Well as of now I’m going to write it off as a bad battery. It’s weird though because it never happened except after a good 20-25 minute interstate drive. Is there any reason why (only) a longer drive on the interstate would cause a parasitic draw to occur?

yes but the new fan has been on for a pretty long time. Not since this issue has started occuring

So the other night when I did the test I didn’t really leave the multimeter connected for longer than a few seconds..

tonight i I was going to do it and leave it plugged in and all and start pulling fuses but noticed that after about 5-6 seconds the draw amperage drops down to .01 and bounces between .00 and .01 (10 milliamps?).

Right when I was starting to think the battery problem was behind me.. today, after a couple weeks of driving the car around with no issues at all, the battery just died cold turkey out of no where. was showing no signs of dying.

so back to where we were. This is the 3rd pc680 battery that’s gotten killed in a month and a half span (since having the built motor swapped in and new injectors put in)

this is really starting to frustrate me.

Thanks a ton. Is there definitely a POSSIBILITY that the alternator could be bad, even though the battery holds fine if I jump it off?

I’m scared to put a fresh battery in this car due to the fact it keeps toasting them. Can’t keep throwing $100 every other week at these.

i do have a charger. every time I charge the battery - it cranks up fine. After cutting it off again though it is dead as dirt.
