i'll try to explain this the best i can... if more info is needed let me know
i have a 72 winner wildcat with a 307 small block chev... i believe it originally had the 160 i4...
after 1 battery went dead,,, i decided to look into it a little more... (pulling a cable off the battery when running kills the motor)
i had the old alt tested & was told it failed... i bought a new alt for a small block & installed it,,, ran the motor & tested the voltage with a meter & its the same as the battery voltage when not running...
the old alt had an internal regulator but nothing was connected to it... the new alt is the same & i installed it the exact same way as the old one...
i looked for an external regulator under the dash & in the engine compartment & found nothing... as far as i can tell,,, the bat wire from the alt runs to the dash ammeter & then runs from the meter back to the battery post on the starter solenoid...
so what gives??? i tried testing the bat wire right off the alt while it was running & its still the same voltage as the battery when not running...
i've looked for info on the web about 1 wire alt setups & theres something about "exciting the regulator to induce a charge"... what does that mean???
i either toasted or bought a junk new alt or the boat is wired wrong...
i'm at a loss,,, any suggestions???
