Here is how to check it,you need a volt meter as Dave said. Then get two male spade ends cimp them on a peace of 12/14 GA wire that is about 3 to 4 inches long. Unplug voltage reg, and start the engine. The plug off the reg will have 4 female spades,with engine running plug the wire we made in #1and#3,if the volt meter don't change, try pluging into #1/#3 starting on the other side of the reg plug.If there is still no change go with Dave and change the brushes. If there is a change replace reg.
