charging issues

OK, the bypass. It is not just enough to bypass the circuit in the engine bay like the article shows. ON my 67, with the ammeter removed, the alternator charge wire goes directly from the alternator stud to the starter relay stud, no8 or no6 wire

But you STILL HAVE to have wiring to feed power into the car. With the ammeter bypassed, the red and black ammeter wires NOW WORK IN PARALLEL as one wire to feed power into the car.

So you need to connect the ammeter terminals together, either solder, butt splice, or bolt and nut and tape them.

BUT LAST you still need to get the terminals for those two wires where they go through the bulkhead in good shape, either clean or replace the connectors, or run new wires, or splice sections to the old and run them straight through the bulkhead connector

So far as the new voltmeter, it goes to a good ground and "switched ignition" so you'll have to get under the dash/ ignition switch and either hook it to the dark blue IGN feed (put a small fuse inline) or find a good place from the fusebox accessory stuff, like heater or radio circuit.

Basically, you only want the meter on with the key. It does put a small drain on the system, and in a month or so of storage, would run the battery down.

There's a thread on here about doing voltmeter conversions. On my 67, example, you can buy a cheap Sunpro 12V voltmeter, tear apart the ammeter, and mount the ammeter face on the voltmeter. The voltmeter has a "trim pot" (calibration pot) inside, and on mine, I set the pot so that the needle reads 14V when the meter is in the center. So when the system is running normal charging voltage, the old ammeter scale is "centered" just like it's supposed to be
