5000D gen

My 5000(74) charging sys. Boils my battery . I am on my 3rd gen and 2nd voltage reg. last one I bought was from NH (made in India). I am about ready to go the alt. route and I want one with the tach drive. I do see them advertised, has anyone bought one of these units? I assume it will work with my standard charging light. Oh yea, I am showing about 14. 4 volts with tractor running. Any ideas would be appreciated.
Thanks,
Ed1
 
14.4 is perfectly fine. 14.7 is even fine. ( 15.1 COULD BE fine, depending on the vreg module )..

PS.. if it had been overcharging ( 14.4 is not overcharging by any means ). i'd correct it via vreg.. not the genny. genny only does what the vreg tells it.

I have one of those indian gennies... works fine.

I did get a non oem vreg though.. not a lucas-ish from CNH though.

Ditto Soundguy. 14.4V shouldn't boil your battery. Maybe it has a bad cell. Check that running voltage at several places on the tractor to verify a bad connection, ground, or corroded wire somewhere isn't causing voltage drop. Include the Field wire between the Genny & VR.
 
I always respect Rick and Soundguy's advice here.
But another thought would be to ask how old is your tach cluster. Do the tach, hour meter, fuel and temp gauges still work.
Those clusters were known for their early failure.
So, because you have a late style block it would not be hard to convert the tach drive to the 5600 style which is driven off the cam under the oil filter.
Then you could use an inexpensive 10SI alternator and have all working gauges plus a reliable/new cluster again - all for about the same price as that alternator with the drive on it.
 
14.4 volts is a very normal charge voltage. The Delco alts regularly run over 15 and work fine as well....
Is it possible that it's charging a lot higher than you realize?

As far as the alts go... the kit that Tisco sells works fine. I just wire the alt directly to the starter pos terminal with a 4 ga wire then run another 14 ga wire from terminal 1 up to the charge light and connect it such that the light has power coming from the key and it receives it's ground path from the new wire on the alt...
You should try to find out if the gen is charing more than you've observed tho... or mabey there is a battery problem. 14.4 v is a very normal number.

All true, Jerry. But the charge rate seems normal. An alternator conversion might not accomplish anything.
We need to be sure there isn't a different underlying reason for the boiling battery.
 
I appreciate all of you guys input! The battery is only about 6 months old, it did the same thing to the previous battery. Also when I put my first gen and volt reg (I owned the tractor for 9 yrs.) I put a new harness on the tractor. I will take the gen and have it checked and see how many amps it is putting out.
Thanks again,
Ed1
 
What you need to do is put a voltmeter on it and see what it's putting out for voltage at rated speed... and check it again in 10 min, 30, min 60 min and see what it's doing then... with the engine running at mid speed or more. If a battery is low it will take time for the voltage to build up. Once it reaches charge then it will climb until it boils...
You've got 14.4V so you know the gen is working fine. What you don't know is wether or not the regulator is A. limiting current, B. Limiting maximum voltage or C. wether or not the cutout is working.
I'd be inclined to suspect that the cutout is simply not working on the reg... contacts welded shut, etc.
It could also be a wiring problem that is not allowing the reg to correctly sense the charge voltage..
First step is to accurately find out what voltage is reaching the battery over a period of time... then you know where to start looking.

Small potatos here but...
He made a couple of comments/statements about his charging system.
Then he said he was thinking about buying an alternator with the tach drive and asked a question about them.
You went into his charging problems.
I went into the merits of the alternator with the tach drive vs a whole new tach, tach drive and cheaper alternator.
Did I not address his question?
 
"Did I not address his question?"
Actually, I don't think you did.
I just happen to think that advocating an alternator conversion on the basis of a 14.4V charging rate and a boiling battery might not accomplish much.
I am an advocate of troubleshooting before investing, not troubleshooting after the investment doesn't yield results.
If you disagree, that's OK.
 
Guys, just to let you know I have nothing against a generator . The first thing I did when I bought my Jube (11yrs. Ago) was to convert it back o a 6 volt pos grd. It has worked perfect for 11 years now. Had to finally replace the battery, after 11years.

It may not apply since yours is a generator but a few years ago I had a Long 2360 that was boiling battery's dry after a few weeks.

With the tractor running at 1800 RPM's I would check the voltage at the batter with a digital multimeter and it was normal.

With the tractor running and at idle I unhooked one of the cables from the battery and connected the multimeter again to see near normal voltage at the end of the cables but at 1800 RPM's and the battery unhooked the voltage jumped to over 60 volts.

A new voltage regulator cured my problems but I have never fully understood what the battery was doing to keep the voltage from the alternator at normal levels until the battery was disconnected and the engine revved up. This was even when hooked to a boiled dry dead batter.

Be careful if you do this. When the voltage jumped to 60 volts I had all of the lights on. The 60 volts blew all the lights along with the electric tach.
