Ever since I got it, my Ford 8N has not charged correctly. Long story shortened, I got the genny rebuilt (it is a 6V system), installed a new 6V wiring harness and CORRECT 6V "A" Circuit regulator, polarized the generator, etc. The problem is the ammeter (which is good by the way) doesn't show charge until I gently tap on the regulator with a screwdriver handle or my pliers, etc. Once I tap it a little, charge rate pegs out at 30 amps for about 10 seconds, then stops. Then the needle goes back to 0 and stays there. I've tried 3 new regulators, and the same thing happens every time. And after a couple weeks, the battery is dead. I'm bumfuzzled! What's the problem here? Thanks

Just shooting a wag here, no experience with this but, here goes. I have in the past had bad grounds do that. The gauge probably grounds and the mount, is the mount any way rusted/dirty/oily, or if grounded by wire, is it loose, frayed, rusty, have a green growth on it? Just guessing here, hard for me to figure it out without see'n it. Other than that, I don't have a clue, good luck with it. ------------- 1955 WD45 S#205467, 190XT #6652 DXT |

Thanks, tried that this evening, made sure the regulator was a positive ground VR like the battery, still nothing, except when I tap on the VR....

| Check the ground to the VR. Mine had a ground strap on the VR. |

Did you put three new regulators on of the smae brand same number? Heard some of the new regulators are nothing but junk . Sounds like you rap it, and helps knock the points together and then it charges for a few seconds and releases and can't regulate. China junk? Dual polarity? Never understood those types. Good luck. andlet us know how you solved it. ------------- He who says there is no evil has already deceived himself The truth is the truth, sugar coated or not. Trawler II says, "Remember that." |

creston,you might reword your title to read something like "bumfuzzled,need electrical held on non charging gen". that way a person with electrical background/expertize is more likely to read your thread. good luck and let us know what the problem was when you get err fixed. |
