Thank you for making this video, it is very helpful! I have a 1951 Chevy truck 3600 (3/4 ton) and am in the process of replacing the worn out 216 engine with a 1954 235 engine and am starting the 12v conversion. Which is how I came to watch your video. Thank you for sharing all the 12v light bulb sizes! Other changes: I had the starter rebuilt for 12v (no selenoid, just step on the starter pedal on the floor), has the original horn rebuilt and converted to 12v,also, got rid of the contact points and did the Pertronics electronic ignition upgrade to my distributor. As others said, for motors, like the blower and wiper motors you cant use the low amperage runtz style 12 to 6 converter you show in the video. You need to use a heavy duty voltage converter for motors. One that works with up to 10 amps of continuous current draw. Great video and thank you so much for making it!
Thank you. I've just inherited a 1953 GMC 9430 one ton school bus. This info is going to be very helpful. Already getting an order ready for vintage auto garage. Thanks again.
Great video!! Just a few things. One, you caught the 6V positive ground, great job!! You will also need to change the voltage regulator on the firewall if still using that. I noticed the gauges in your truck are actually Chevrolet, not GMC but that is OK. The voltage reducer you are using for the fuel gauge is only good for the fuel gauge. You would need a heavy duty, hi amp reducer for the radio and heater motor. The headlight switch is debatable. The ones I have that are original have a thermal circuit breaker so they would be specific to voltage. In most aftermarket parts catalogs there is a 6V and 12V for this reason. Lastly, the horn should be changed out for a 12V horn. I would check the part number because that is not the original horn I don't think. On to the next video!!
Pretty good video.. But missed the part number for the 12 to 6v adapter reducer.. You whipped it out in a big glare turned it over in lightning speed so could not see the part number...???? Thx..
I have a 12v conversion in my 51 Chevy and my alternator took a shit. Alternator has 1 wire. Where can I find a replacement or which one can I use preferably local parts house
I have a 1952 Chevy that i have been doing work on and when the truck was painted internally they sprayed over the center speaker and glove compartment panels. I have stripped the paint from the top and bottom of the speaker grill area but it looks like the whole glove box door is also stainless or is that aftermarket? looking to at least strip down the top and bottom to match the center grill if possible. any idea of what the door is made from?
Wait Im so confused on gmc 😩 I have a 1954 gmc im not sure exactly what it is but I do know it was a flatbed and it has been taken off and the frame has been chopped to look like a 3100 everything has been moved and it’s ready for new fuel lines and brakes lines and drive shaft , now I’m tryin to get the inline running but I can’t find anything about it and I know it needs a 6v battery but my starter wasn’t turning but I’m not sure if what I had worked, I had a battery charger on it with the 6v on. Any information will help !
Sounds like you have had everything modified on it, would be best to check all the wiring in your case and verify it’s hooked up right. Also test to see if your starter solenoid is working. Plus GMC factory was 6v positive ground. So keep that in mind. If I was you and all that had been done. I would think about a new wiring harness
Mine was already on a negative ground system when I got it so I didn’t have to change anything. If yours is still in a positive ground setup it will work just fine but the ammeter will read negative amps. To correct that just swap the wires on the back, it will the read positive amps as it should.
The start solenoid will work just fine. Actually work really welll on 12v. Definitely won’t have the same life span but ppl have reported years of use on the 6v solenoids after 12v conversions

Glad I could help
VERY GOOD I HAVE A 53GMC 5 WINDOW AND I CHANGE TO ALTERNATOR BUT HAVE LITTLE PROBLEMS WITH THE WIRE THANK YOU SO MUCH KEEP IT UP BLESSINGS
I’m glad the video helped!
Great video. Thanks. This was a helpful.

The ones I have are aftermarket, but stainless was an option from the factory.
@9:27-Isn't there a bulb within that hydramatic shift selector that would need to be modified for 12 volts?
Yes there is! It very specific I didn’t include it
Great video, been thinking about converting my 54 Chevy Bel Air. Just need to look under hood to see how close this is to your truck. Thoughts?
Should be very similar, I would just check the wiring diagram and follow the line from the generator back to the starter. GL! It’s a great upgrade
@@Ev3rydayGarage Thank you, I will check it out!

Was there any modification required for the Ammeter?

What about the starter solenoid?

Looks like a generator to me
It’s an alternater from Powergen. They make them to look like generators
