Hi, Moose,
The first thing I would check is whether you have juice at the on-off switch. What you have so-far described indicates that there is no power getting to the unit. A simple circuit tester on the two leads at the switch should tell you yay or nay.
If you have no power, then you gotta trace back to the batteries. (The unit should be directly wired to the batteries, bypassing any other circuits or switches).
If that's working OK, then the problem is probably with the stove. But I doubt it, especially if you are getting no light, no fuel pump sound, and no indicator light.
If fuses can be bad but not look blown, that may be something worth looking into. Not likely, but still worth looking into before shipping the unit off.
To me, yanking the unit and shipping it to Scan is the absolute last resort.
Although Karl at Scan Marine is a little hard to understand with his European accent, he is really easy to work with, and extremely willing to help. Don't hesitate to ask him to repeat himself - he knows he has a pretty heavy accent.
My recent experience with Karl when my fuel pump pooped out was excellent, and he walked me through a really sensible set of diagnostic and corrective steps. Pump is back up and running perfectly!
