Ford 1910 Mechanical Voltage Regulator swap to solid state

rdgemmill · Nov 4, 2020

Hi All,

I have a '84 Ford 1910 that had the OEM mechanical voltage regulator that was putting out just a little over 17 volts to the battery. I have no idea how long it had been doing that but thought it would eventually fry the battery so I replaced it. I ordered a mechanical one but got a solid state unit instead. I waited too long to send it back so I'm stuck with it. It is not charging the battery. I've read posts about this before but I can't remember where but the guys who posted about it said they had to reroute some of the wiring. The manufacturer of this unit show the hook up exactly like OEM. Does anyone know what I should do to make this work? All I get is the battery light with the key in the run position but no charge voltage to the battery.

Thanks in advance for any advice someone can offer,

Richard

I used a Datsun 280z regulator on my 1980 Ford 1900. It was a replacement electronic unit vs the old buzz mechanical one. Worked fine for at least 5 years on it till i sold it last year.

Thanks Dave for your reply - unfortunately I dont have much. I got the box and the regulator. The plug, according to the importer is the same as OEM, see attached photos. I have also attached photos of the plug with the backside of the VR and the box label as well as the cross reference applicability. I hope these can help you out.

Thanks,

Richard

Thanks Steve, I will look for that if I cant find a solution to the POS I have already bought.

Best Wishes,

In general Usually there are 3 prongs. 2 are ac voltage in from the starter. The third one is b+ 14.4 DC to batt
I've used a few motorcycle regulators on small engines who's rectifiers went bad. The motorcycle ones have large heat sinks and last forever
