Noticed another problem... periodically, the voltmeter drops from 14.3 to 12.5. Glance down about 30sec later and it's back to normal.
Jim, I had the exact same issue. Turns out it was just the reg/rec connection. Was thinking my reg/rec must be on the fritz, but it tested out good. While I had carefully cleaned all electrical connectors, it appears I was overly generous with the dialectic grease. Cleaned the grease out of the connection, sprayed it down with electric contact cleaner, and good ever since. Lesson learned on dialectic grease.
