Well it IS an issue "sometimes." The later cars had the big white connector under the hood to separate the engine harness (Thanks Redfish) This thing deteriorates and needs repaired, so inspect it THE MAIN alternator output wire goes throught hat. Also the bulkhead connector/ ammeter circuit is an issue. Inspect the bulkhead connector by separating the connector halves and look carefully. READ the "MAD" article for insight

Also CHECK charging voltage when you get it all running. With engine warm and battery charged "and normalized" check charging voltage with accessories off and engine on fast idle. If it is much over 14.5, look for problems in the circuits above as well as the ignition circuit. VOLTAGE DROP through the ignition "run" circuit causes over-voltage/ over-charging
These girls varied from 37--65 BUT FACTORY 65 alternators HAD A MODIFIED CHARGING CIRCUIT known as "fleet/ police/ taxi" which partially bypassed the bulkhead connector
