Often in the older cars, the voltage regulator can cause the alternator to "full field" all the time, and it will eventually burn up the windings or "smoke" the diodes. unlike later cars, the regulator is external (hanging on the firewall).

M&H Electric in SoCal has complete harnesses for these cars. They're very good.

As for a "local tech" that can help you, ask car clubs, modern repair shops, etc., where they get their's "done".
