That was what I was getting at. It's the fastest easiest thing to do. No power in= no power out.
I don't know what you have access to but a $25 equus self ranging multimeter from autozone would be a cheap investment. Mine doesn't do everything my uncle fluke does obviously but the the readings are dead on on the few test I've done with both.

That looks good. Now go in and with it warmed up and idling, turn the foglamps and the blower all the way up and take another voltage reading at the battery.

15v is actually too high, especially if it's a flooded cell battery.
Here's a good trouble shooting flow chart.
