voltage regulater help

FLOPGUNS · Dec 21, 2014

Hello, need some help with my Super-A with 6v pos ground. Has been a headake goes through about 1 regulater ever year last one worked good for about a year then it got so you would have to tap on it to get it to work . so today put a new one on it fired it up . charging good let it run about ten minutes looked at the amp guage was discharging taped on the regulater started charging again afew minutes later it was discharging again. help in north carolina

Try running a ground wire from the regulator to the generator. Regulator has to be well grounded.

I went through that with the last 6 volt tractor that was left on the farm. I figure I went through $150 in regulators in about 6 months. That's when I bought a $39 alternator and threw in the towel. No looking back.

Where are you getting the regs and are they made for the gen#as they do need to match. Second are all the componets in the system grounded all the way to the lite sw. Has the gen been checked new brusher ect. Very important to have the gen and reg made for each other. Those systems have been around for 60 pluss yrs and still work great but need to be in good repair and have things rite.

Voltage regulators surely have not become any better over the years, however, even back in the 60's & 70's I had to adjust a lot of new regulators for proper voltage settings. We had a good piece of test equipment that would simulate full charge or low charge batteries so you could get a good setting. It was a no no to open up a regulator but you knew darn well that if you went to get another new one and turn this one in for warranty that would not fly either. The three unit regulators were always much better as you had separate current and voltage regulating units, not the combination type with only two units. One unit was cutout, and other is combination current and voltage. Like a representative from Delco Remy told us once upon a time, that never really worked very well.

hello, i hate to go to a alternater , will try grounding it to see if that makes any difference, has any body used one of the alt that looks like a gen ? ( shocked in the carolina )flopguns

I have six 6 volt tractors, four "restored". True they don't get much use, but the ignition parts including regulators get replaced with CaseIH products by the numbers in the parts books. They all work. Stay away from farm stores for those parts. If you don't have dealer nearby and don't want to order, NAPA is probably ok, but no promises. If my tractors come 6 volt they stay that way. If any come with alternators (one) they stay that way too.

For one thing, a Voltage Regulator should be compatible with whatever ground you have, be it Pos ground or Neg ground. Another thing is way back when a Voltage Regulator was more closely matched to a certain generator while nowadays it (availability) may be more of a one size fits all approach which sure will still "work" but not near as well as if the genny and VR are more closely matched as I suspect was the case in the fifties etc. A VR plus the Genny BOTH need a good ground to work properly.

Everything that needs grounded , needs good tight clean connections. If you have a positive 6v system, then you need a 6v positive ground regulator. You can get others such as negative ground regulators but its not what you need and you will likely have problems if trying to use one of them. Generators commonly need to be polarized after some of the electrical system has been apart and back together. If it needs polarized, it will cause a dis-charge rather than a charge. Other components need to be good for the system to work. Good battery, generator, and so on. One more thing, it doesn't take much at all to mess up a regulator. Like allowing the generator to dis-charge from not being polarized will just fry the dang thing in pretty short order.

two of the regulater were case 6v pos ground around $ 50.00 each lasted about a year each . 3 were aftermarket about $ 25.00 each they lasted about a year each the one i put on yesterday lasted about 10 min, i polarized it first 6v pos ground keith

Since no one is going to warranty a voltage regulator anyway, take the cover off and look at the points. Normally, not running , cutout will be open and regulator points will be closed. Then start it up to see if cutout closes to indicate it at least tried to charge. Watch the regulating points for arcing. If so, clean them with a dollar bill. If still no charge, ground the field terminal with jumper wire. That will show you if generator is capable of charging as it eliminates all regulation. I suspect your problem is the generator that is causing all your regulator problems. Not matched to a regulator. Probably a rebuilt unit with lord only knows what parts are used. I cannot tell you all the different things to check from here. Way too many but I do know what I would check like field current draw for a start. Too much field current burns up regulator points with regularity.
