Hi All,
I recently acquired a '53 GMC that is "partly" converted to 12V. As of right now, the ignition circuit and engine runs on 12V, but that's about the sum of it. In light of this (and my general inexperience with wiring), I'm planning to purchase a replacement harness in the coming weeks to help with the conversion and repairing the wiring. I noticed that Jim Carter and Classic Parts both offer 12V Alternator harnesses, but details on what they do and don't do are kind of vague. Generally Jim Carter seems to have higher quality and more experience with AD trucks, but the difference is almost $100. Has anyone had experience with either harness? Able to tell me about the goods, bad, and "others" with either harness?
