Bought a '49 Super A, a week ago. My 'ampere'-gauge reading is in the negative when idling, and dives for the cellar when throttled up. I've traced all the wires, and found that many are disconnected, but here's what I got:I'm assuming I have an alternator. There is only one wire from that, attached to a post named "BAT", and that wire goes to the 'amperes' gauge. The other wire from the 'amperes'-gauge leads to the starter, with a 2nd wire from that 2nd post leading to the engine cut-off switch. A wire leads from the 2nd side of the cut-off switch to a coil post. The 2nd coil wire leads to the distributor. The POS cable from the battery goes to that same starter post. The battery NEG goes to ground. And that's it. Other wires lead to where must have sat a bulb(?) underneath the cut-off switch, and several wires associated with a switch labeled successively: L H D B. All those are connected, but apparently non-functioning. I have no headlights, and one taillight, with it's wire cut by the light's bracket. I used a multimeter on the battery while it was running. It read about 13 volts while idling, and went slightly higher when throttled-up, so it seems that I don't have to worry about the battery dying at the far ends of the fields. So why is my amperes-gauge behaving like that? Any suggestions? And as I seem to have an OK charging system, how is it regulated? Is there a regulator within the alternator, as there is nothing on the outside of it. And, does anyone have an original schematic of the wiring? Thanks
