My truck won't start after overcharging the battery. I changed the voltage regulator/alternator and the ICM. It still won't start. How would I check the coil? Would the hall sender in the distributor be suspect after charging at 18v for a couple of days? What damage and to what could result in this short period?

Find the green white wire out of hte hall sender on the side of the diz.
Mark the DIZ to the block, now loosen the clamp.
Ignition on, if you move the shutter of the Diz the Green/white wire will go from 11-0V or 0-11 which means it is working.
I would first suspect the fusible links. They are the large wires off the battery. If you pull on them in the middle, they will stretch and that is usually a sign that the wires fried. (butt-to-butt) jumper around them or replace them.

If the ignition was off I can't think of much damage occurring other than the fusible links and possibly the battery is toast.

the damage from overcharging (18 volts) for a couple of days was apparently only to my coil---replaced and everything is fine---I did rewire and replace the linked sectiions, but nothing changed until I replaced the coil
