How to do a 12v Conversion on a 1947-1953 Chevy/GMC truck using a 1 wire alternator.
In this video I walk you through a 12v conversion I have already done on my 1953 GMC truck. Almost all of the information should apply to 1947-53 GMC/Chevy trucks. I will be using a one wire alternator in this video however an externally regulated alternator can be used. Here is the link to the free 12v conversion packet from Vintage Auto Garage. https://vintageautogarage.com/how-to-... 1947-53 GMC Wiring Diagram http://www.oldgmctrucks.com/photos/GM... 1953 Chevy truck wiring diagram http://chevy.oldcarmanualproject.com/... A list of the bulbs you will need. Remember, every bulb will need to be changed to 12v 1.) Two 6020 Halogen Sealed Beam 7 inch Headlights 2.) One 1073 bulb for Dome Light 3.) Four 67 bulbs for Tail Lights 4.) Six 57 bulbs for Gauge (4), High Beam (1), Ignition Switch (1) The internally resisted 12v Coil that I am using in the video. https://a.co/d/66t9qS1 As always thank you for you support! #1953GMC #hydramatic #12vconversion
