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!

Not bad. I am about to install a 6V positive ground one-wire alternator in a '54 Hudson. I might suggest adding some subtitles about correct fanbelt tension, keeping wires away from intake/exhaust manifolds, and the BAT terminal of the old external voltage regulator is also often used as a place to connect power for circuits such as ignition switch, main circuit panel, etc. These circuits must be connected to the 'one wire (hot)' of the new alternator, not taped off.

I had a secondhand alternator from my Elky and placed it in my 1960 Brookwood, this video helped me a lot, fixed in 15 min. Thanks

Great video, I just swapped out my generator To a alternator on my 1956 Chevy . The swap was very easy. Go for it.

would people ever understand that....""the truck came with a 12v jst had a generator instead of a therefore all the equipment as a starter, coil, radio, heather, lights and sour cream on ur frito pie is a 12 volt for your video mike....well done, am trying to bring a willys 59 to life and i am stuck with electricall issues, , its how i came accross yours...good job!!!

[dunderheadgood]

this video makes my life a lot easier, thanks! swapping my ‘62 studebaker lark today!

This looks a lot more simple than I had imagined. I have a '62 Scout 80 that I want to convert. This helps a lot. Thanks for the vid

Just for those interested in the technicalities. You mean you upgraded from a Dynamo to an Alternator. They are both Generators. A Dynamo produces DC using a mechanical rectifier called a commutator and regulates via current and voltage sensing relays; an Alternator produces DC using silicon diodes and is regulated by an electronic circuit, this may be internal or external.

Very informative. Working on a 59 belare

Just the start I needed before doing this on my 52 Mainline tomorrow. Thanks!

Great video I am taking my old C40 Lucas generator off my Triumph convertible and going to put an alternator on

[sundiau]

This is just what I have been looking for. Thanks for posting this video!

I love old trucks, and I love old Barns, now I need an old barn to to my old truck in

[DougABirnbaum]

Could you do a video of the connected wires from the ammeter to the starter? Having issues and looking for help with mine. Thanks

[DinkAround]

The 60's models will have a 12v system. Almost all cars and trucks after 1955 came with 12V. There was a few 55's that made it out with 6V but after that 12V was equipped.

great mods!
I am about to do two 1940 Ford flathead pickups from 6-12 volts
they were originally positive ground!
I will be switching to negative ground.

[joshuahughes]

Where did you get the alternator with bracket kit?

[DinkAround]

No conversion was needed on this truck. The 59 chevy trucks came with a 12 volt system. Was a straight swap.

Thanks for watching

[danielb]

Thanks for that, because I want to convert my Ford Taunus 17M 1965. You obviously have to replace all your light bulbs, for lights and dash lights. What else must you change.?

[frankiedeleon]

You sounds like the greasers! Awesome :)

10 si gm alternators don't need any extra wiring, they self excite around 800-1000 rpm, only the main red wire to battery is needed, the two tabs on the side (yellow exciter wire and the other for dummy light) can be left off. For those of us who like extra instrumentation can run amp meter or volt meter in or under your dash.
