It turns out that the inexpensive jumper cables melted and disconnected. That probably limited the amount of damage.

Bought a battery maintainer, but the original battery would not charge. We installed a new battery and it started right up. The garage filled with clouds of smoke, but after a few minutes of running it cleared. It has not been run in about a year so I guess that it has some oil leaks.

Went for a short ride. Runs great, everything seemed OK, but the ABS light came on. The ABS fuse was blown. Replaced it, but the light is still on. ABS control unit fried? Is it safe to drive without ABS as long as the driver is aware that it is not working?

The battery light is off when the ignition is on and on when the ignition is off. The battery voltage stays at 12.1V with the engine running. Just a fried voltage regulator? I would be surprised if the diodes were fried because they are designed to work with reverse voltage.

There is a constant 3A draw on the battery with the ignition off. Pulled all of the fuses and relays and saw no difference. This probably supports the fried voltage regulator theory.

It sounds like there is an exhaust leak on one cylinder under acceleration. Just a gasket?

Thanks for your help.
