My fiance has a '79 Brat that was left to her, and it's having a fueling issue. That is, it was running fine then sat for several years. I put a new battery in it and nothing. If I hot wire the fuel pump it comes on. All I have been able to find is something stating that the alternator sends signal to the voltage regulator which then tells the pump to kick on. I cannot find an actual wiring diagram. It had a new alternator and regulator just before storage; it has another new regulator and the alternator was tested as being good. Tested twice, actually. Nobody can tell me if there is a relay or something, and as I said, I cannot find a wiring diagram anywhere. Does anybody out there have one? Or have any ideas? It would be most appreciated as she is most vocal about this being running ASAP. I should also note that I have power at the fuse.
