On the way home from Branson, cruising down I44 the chief navigator said she smelled something strange. The voltmeter showed 18 volts, but I didn't get excited as I had recently recently returned a similiar gauge for false output. Pulled on the headlights to try to absorb extra voltage if it was really there. Next was smoke from the radio and a loss of engine power and a loud bang.

We pulled to side of the road and the engine would not restart - no response from the starter. Checked the battery compartment and engine battery had smoke rolling out of both ends at the top cover joint. Cooked all of the incandesent bulbs but the LED clearance lights were fine.

We installed the battery from the toad and the coach started fine. We drove off the interstate to a safe spot to work. We found the alternator output was zero. So, off to O'Reilley's for a new battery and alternator. Got her back together and running and the only apparent damage was light bulbs, fuse for the heater/air con and a tach that doesn't work - oh, and both mufflers are a new shape with side seams slightly opened. We had the APC installed on the alternator.

The coach ran great the remaining 400 miles home.

Is the APC comprimised by doing it's job, or is it a safe reinstall? (It is back in place now)
