Electrical Question

Since installing new batteries in my 2150 the amp meter stays on near full charge all the time. It has been run enough hours that any low charge condition that might have existed in the new batteries would have been satisfied. I was told the regulator needs to be polarized. Could this be the problem? If so, how is this procedure accomplished?
Thanks

Thanks, I appreciate the time you gave for your responses. I can surely sort out the problem with all this information.

Not to detract from what the others have said but if your tractor has an external regulator delco alternator I would wonder about the regulator at this point. Heavy charging on the new batteries could have done it in and I can't find a decent mechanical regulator any more.

I suppose you could put on the built in regulator model but I found you can wire the external regulator that Ford used on many of their vehicles. I can't tell you the wiring off of the top of my head but I can tell you that it works perfectly on a 1950T.

You could also have a bad battery. While not exceedingly likely stranger things have happened.

NAPA sells the Standard VR103 external regulator which is an exact replacement for the OEM.

Well, That my point. If it is an EXACT (Mechanical) replacement, I don't want it.

Why not? The OEM mechanical one on my 1650 is 35 years old and still operates perfectly.

I don't doubt that you might have one that lasted 35 years. But once it quits I can't seem to find one that would work another 35 years. A year if I am lucky.

The electronic one has the mechanical beat hands down. It fits very neatly and operates better that the mechanical one ever will.

Now if you're a purist and say that's not original, I can see that but what about the Cummins repower. I think a Ford should have a Ford motor. Same for my Olivers or whatever.

You should have an alternator and do NOT try to polarize,they don't need it.If you have generator and its over chargeing then it don't need polarizseing either.

That's what I was thinking Larry. It seems to me that the amp meter did nothing before polarizing. just stayed in one place(normally "0"). It's been a while since I have polarized one.

If the batteries were not fully charged when you installed them, you may have damaged the alternator. If you installed fully charged batteries then I would be looking for a wiring problem... both cables and the terminals they attach to must be clean and shiny. You can back trace with your DMM and see where the voltage drop is.

You polarize a regulator on charging systems with generators. The first thing is, do you have a voltmeter and did you put four six volt batteries in or two 12 volt batteries?. I would take a voltage check with a good volt meter. Every mechanic should have one. Also check each battery and the connections between each battery,bad connections will trick the charging system into thinking it has to charge more. Your batteries should show 13.6 volts for a 12 volt batttery no matter if you have two six volt ones in series or a 12 volt on each side. Now I am making a statement, but if your voltmeter at the alternator reads more than 14.5 to maybe 15 MAMIMUM start looking for voltage drops through the connections or a problem with the regulator or the alternator itself. Make sure you have the batteries charged at 13.6 volts (full charge) when checking the alternator or regulator. We serviced more of the 2050 models (same set up) and I remember they would peg the ammeter for a while after you started one. Hope this helps, If not oh well it was free.
