buy a cheap test screw driver and hold one side of fuse and touch to other side with the screw driver if the light lights up fuse is good if not trash....

That's another way to do it...but a DMM is a much more useful tool IMO....can't set a gain with a test light, for example

I'm pretty sure I've narrowed it down to my GMOS-01. It says it'll retain door chimes and such but it doesn't. I'm thinking I need the GMOS-04 as I do have the factory amp in my car.
