Re: Farmall - charging system
It should show some amount of charging. I'll assume you polarized the regulator. You might want to try testing the regulator with a multi-meter, to make sure it is putting out voltage. If it is, then check wiring back to the amp gauge. If it isn't, depending on where you got the regulator, and buddy of mine, and I both got a regulator at TSC more than several years ago, and quit working shortly after installing. We both found that the rivet that fastens the little ground strap to the base, under the cover was loose. He took his off, and took a punch and snugged it up, and it started working again. I on the other hand, took a set of spread jaw Vise-Grips for welding, and clamped it tighter in increments. The rivet is aluminum, and the Vise- Grips are a larger set, so it tightened it up pretty easy. Mine also started working again, and has ever since.
It's a shame a company hasn't come up with a solid state regulator, they would make millions selling them. Not saying that is your problem, just something to check, if you overlooked it.
