The Conversion with an Alternator

An alternator conversion is slightly more complicated than generator conversion, but it's still pretty straightforward. (Again, all parts are available from Patrick's Antique Cars)
1.Disconnect the battery.
2.Remove the 6V generator.
3.Mount the Alternator. Brackets are available from various manufacturers.
4.Use a "DA Plug" which allows you to eliminate the old voltage regulator. Attach the short wire to the alternator post. Attach the long DA wire to the ignition switch so it is powered only when the switch is on.
5.Remove the voltage regulator, and connect the BATT wire to the wire that previously ran to the generator. Attach this to the alternator post (along with the short DA wire).
6.Replace the 6V Coil with a 12V Coil. Use a coil with an internal resistor or install an ignition ballast resistor in the wire between the coil and the ignition switch.
7.Replace all light bulbs. Don't forget dash/instrument lights and turn signal indicators.
8.Replace all flashers and relays.
9.Install the above listed Gas Gauge Voltage Reducer on the rear of the gauge.
10.Install the above listed Accessory Voltage Reducer in the wire between the heater and heater switch.
11.Make sure all other accessories are 12-volt ready.
12.Reconnect the Battery and you're done!

This information is believed but not garaunteed to be correct.

I opened this thread hoping it applied to my 55.2, but nope.

THIS is one of those examples where the '47-'55.1's(I THINK) and the '55-'59's should have their own forums. Or at least, a moderator puts something is parentheses after the title to distinguish.

I did this swap on my 59 chevy apache, with a 235. If you have a 12v the instructions just involve not replaceing 6V parts.

Good luck
