H charging problems....again

Anonymous-0 · Sep 28, 2010

I was having good luck with my tractor charging. Then i was going through the woods to cut a field and hit a bump and it quit. Ive tried just about everything but no luck. Then once in a while i look at the ammeter and itll show positive charge. Any ideas on what i should look for? and is there an easy way to check out whats wrong with it? Any help would be nice. Thanks

Its also a magneto charging system and has the voltage regulator mounted on top of the generator.

If it is operating correctly it will charge only enough to keep the battery fully charged. If when it is started it charges for 15 to 30 minutes, then goes back to near no charge, it is just fine. Battery voltage is the key to this. If it is at 3/4 throttle the battery volts should be a 7.1 to 7.3 (use a needle style meter, or a very good digital) mediocre digital meters will bounce all over the scale. If it is not charging, the voltage will be about 6.3 volts (or less) Jim

You are confused somewhat there is no magneto charging system. What is the Delco Remy # on your generator and how many terminals on whats on top. If the batt connection is by itself and two terminals on the other side it is a cutout. You mite have a loose brush in the genny or another connedtion thats loose somewhere. Are you running pos ground and is the tractor still 6v.

As long as the battery is being charged enough so she always starts, I wouldnt worry all that much just yet. It could be worn down brushes in the genny or sticking corroded brush hold down springys or burned carboned contacts in the Voltage Regulator (if it has one instead of simple cutout relay) or a bad grounded or worn switch contact in the LHBD switch if thats what it has (used with 2 wire simple cutout relay systems). Other minor problems may be a bad ground or a loose or corroded connection or even a loose fan belt.

If it gets to where it isnt charging at all run Par 5 of my Troubleshooting Procedure which will tell you if its a generator versus a Voltage Regulator or other problem.

For now Ima goin with the genny brushes are getting short or theres a bad ground or other connection (like a bad ground in the LHBD swith or it has resistive loose contacts) and if it happens to have a Voltage Regulator (instead of a simple cutout relay and LHBD ligh switch)it has burned carboned contacts or a bad ground.
