Owner of a 1970 Charger SE. 383 four barrel. Any advantage to a one wire alterntor as opposed to the stock charging system and how do you wire one? I have a 100AMP alternator and thinking of going that direction. Also considering using a voltage meter instead of the stock amp meter. Understand that there may have been issues with the AMP meter on Mopar’s?
One wire alternators are notoriously lousy because they are unable to accurately adjust the charging voltage in response to ambient temperature changes. They tend to cook batteries!
It wasn’t so much the ammeter that was a problem, as much as the bulkhead connectors, which all charging current passed through. If you convert to a voltmeter you can connect the ammeter output stud directly to the starter relay stud (with a maxifuse or fuse link) and prevent that problem. If you, however, greatly increase the alternator’s maximum output, be sure in use proportionally heavier gauge wiring throughout.
