Battery drain mistery? Alternator?

throw the batt on a trickle charger overnight.

Ok, my battery is charging at 2A overnight.
You said that car should run after negative battery wire is disconected so would that mean that my battery isolator switches are failing ir mine dies? If so where do I look for them?

you do NOT have isolator switches, thats an aftermarket racing product. its designed so you can take the battery out of the charge system right after starting so you have more horsepower.

the transistorized electronics in the alternator should be able to keep up with the current drop from removing the battery from the system, as they are easily able to keep up when you turn off the low beams!

double check the electrical grounds in the engine bay, and make sure the bolt a the B+ junction box is tight and there is no corrosion down there.

Ground cable looks tight and no rust anywhere. Trickle charged battery is holding overnight at 12.4 -sweet. So it looks good so far with the problem fuse pulled. Thanks Billion
