I have a ford 801 tractor and the the battery will not take a charge while it is running. I have an 8 volt battery with a 6 volt generator and 6 volt voltage regulator (positive ground). The tractor has a new battery, voltage regulator, and a new generator. When the tractor is running I pull the positive cable and the tractor stays running. Does this mean the generator is working? When I charge the battery on the charger it will take the charge and stay charged for aboutabout a week. The battery does not go dead if tractor is sitting. Can anyone please help? Thanks.

You said the battery looses charge when the tractor sits. Maybe you don't have a charging problem, but a discharging problem. Maybe the light in the glovebox isn't turning off. If the battery goes down sitting for a week, it has a load or aninternal short draining it.

When the tractor continues to run with the battery disconnected indicates that the charging system is working but may not be putting out the poper voltage to keep the battery fully charged. Do you know what voltage the system is putting out. It may be good enough for a 6v battey but not the 8v that you are using.

Thanks for your reply, I appreciate it. I don't know the voltage the system is putting out. Is there a way to check the voltage of the system.

The most simple way to check your system is just as you have done by disconnecting the battery but use a voltmeter.Connect the volt meter across your battery andit should read 8v disconnect the + ground with voltmeter connected to ground cable-this takes the battery out of the system and your gauge will read the output voltage from your charging system.

I checked the batter with the volt meter with both cables on it and get a reading of 8.1 volts.
While the tractor was running I disconneted the positive cable and checked the current again and the reading was 7.0 volts. I'm assuming that is not enought volts to charge the battery. Do you think if I go with a 6.0 volt battery that the charging system will be fine? Thanks again for all you help.

This is good information and indicates that your charging system is in good shape. From a working standpoint charging an 8v battery to 7v results in a dead battery.I would suggest that you change to the 6v battery .

I will try a 6 volt battery. I will let you know what happens. Thanks again.

I will check the charging system with a volt meter tonight when I get home. I will let you know, thanks again.

You need to measure your output voltage. You will need over 8 volts to charge the 8 volt battery. A 6 volt regulator is set up to only put out enough voltage to charge a 6 volt battery.
Your regulator may be where you can adjust it to put out enough to charge the 8 volt battery. IF not I think there are regulators available that are adjustable. Others on this board can clarify that...Good luck

Thanks a million for the information. I will check to see if I can buy a voltage regulator that is adjustable.
