Chris,

The battery does get charged through the battery switch. You need to be on "both" to charge both batteries.

Rebuilds can be cost effective - see what the cost is for a local rebuild and compare to a new or rebuilt unit. I assume the rebuild includes bearings, and they will checkout and replace any of the electrical parts that may be fried.
