D0NN10505A 12-Volt Regulator Assembly Specifications

The D0NN10505A is the part number for a 12-volt voltage regulator used in Ford tractors. Voltage regulators are part of the battery charging system. They are used as a control device that keeps the voltage flowing from the alternator within the voltage of the battery - in this case within 12-volt range. These voltage regulators are mounted on top of the tractor alternator. Typically, voltage regulators should be changed when the battery is replaced.

Models

The The D0NN10505A is used for a variety of different, but older model Ford tractors. Ford tractor models that the voltage regulator will fit on include models 2000, 2110LCG, 3000, 3400, 3500, 3550, 4000, 4110LCG, 4400, 4500, 5000, 8000 and 9000.

Mounting

Mounting the D0NN10505A voltage regulator is a straightforward procedure. Wires running from the alternator connect to the voltage regulator terminals. There are three terminals on the voltage regulator - positive, negative and ground.

Dimensions

The D0NN10505A is not a very large part. It measures approximately 4 inches in length and two inches in width and weighs just under two pounds. It is made to regulate 12-volt batteries.

Upkeep

The D0NN10505A is not considered a serviceable part. If it goes bad, it should be replaced. However, if the tractor does encounter starting problems, the voltage regulator can be removed and cleaned with a wire brush.
