We really need to know what the charging voltage is. There might be nothing wrong with the system at other than an ammeter that is a bit more sensitive than most, as indicated by the amount of discharge with just the switch turned on.

The battery gets drawn down when the starter is used and will except a high charge rate for a period of time as it recharges. The amperage should drop down as the battery reaches full charge. As long as the charging voltage is no more than eight volts at the battery you should be alright. Closer to seven volts would be better.

A fully charged six volt battery should have 6.3 volts. 6.5 volts will charge the battery but it will take a long time. A tractor that is used regularly for more than short periods at a time will be OK with a charging system that maintains 7 volts. Much more than that and you will have to keep adding water to the battery. Tractors that get run less frequently and for short periods at a time will do better with a higher charging rate. The higher the voltage the quicker the battery will recharge. The higher the voltage maintained while charging, the more likely you are to boil out the water.

Today's Featured Article - Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U ... [Read Article]
