After sitting for awhile I started up the Twinkie II. With the engine idling high the alternator was putting out between 16- 16.5 volts. After it warmed up it settled in around 14.7 at idle, which is more what I would expect. The batteries are on a maintainer so they were fully charge before starting.

This voltage at startup seems a bit high to me. Should I be concerned?

And yes, I do have the APC installed ;o)
