For the alternator not charging, make sure you have full battery power on the large 8 gauge wire, and the smaller wire should have power when the ignition switch is turned on. If the alternator is still not charging, you can remove an allen key plug towards the back of the alternator, and with a small electrical screwdriver, turn the rheostat to increase the voltage.
Re the engine not shutting off, the usual cause of that is that the field wire from the alternator is feeding power back to the distributor. That is another sign the alternator may be pooched. Last edited by rob love; 26-10-18 at 05:15.

Yes it is,so that doesn't explain why your vehicle keeps running after the switch is off, but does explain why the alternator won't charge. It looks like you may have had a small fire under that cover. The two small leads over to the inernal regulator are also burned up, and your field wire is missing altogether. It is possible that it was a short at that location, but it's also possible the alternator went to an overcharging condition and burned itself up. I would suggest someo disassembly is required.
There is no cheap source for thsoe alternators that I know of. Expect to pay between $300-600 for anything on line. I used to sell them for $125 back in the day when I bought 30 M151A2s, bot those are long gone.

Starter questions
Was wondering if the starter switch is repairable by buffing the contacts . I push the pedal now nothing happens
But I can jump the starter to get it spinning.

Yes, the starter switch can be removed, taken apart and cleaned up.
I have found that switch to be a source of battery drain. The contacts shed dust sized coper particles, that eventually form a trace from the power terminal to ground.
