Melted distributor rotor and cracked dist. cap
Left charger on car with the key on for a couple of days. Big mistake. Found that the rotor, dust cover and cap were toast. Replace those items and still wont fire up. Any ideas. The electronic pick up wasnt melted but could be bad. Any ideas out there?

You will need to check for melted wiring in the HT system and HEI module, if the rotor has melted there was significant current flowing in the system. It is also possible to fry the ECU if you leave the battery connected and then add the charger, depending on the type of charger. I always leave my XJS on trickle charge but remove the battery neg terminal before I connect the charger.
Can you measure the voltage (on the low voltage side of the coil)
a - across the coil + and - terminals
b - from the + terminal to earth
c - from - terminal to earth
and post back

"HT" = High Tension = the high voltage side of the ignition. Coil output, distributor cap and rotor, plug wires.....
Sometimes referred to as the "secondary" side of the the ignition system, with the "primary" side being your low voltage stuff: wiring to the coil, breaker points (remember those?), ignition modules, etc.

If this is ok disconnect the wire at the coil Negative turn the ignition on and measure the voltage between the coil negative post and ground, you should have 12volts.
