I saw the post on the GTV that died because of a blown fuse. A few days after buying my GTS 250 I made a list of the fuses used but I haven't gotten around to buying them. Perhaps that post will get me to an auto parts store. The GTS 250 has 10 fuses in the following locations:
In the glove compartment
7.5 AMP
7.5 AMP
7.5 AMP
10 AMP
10 AMP
15 AMP
In the engine compartment
3 AMP
7.5 AMP
10 AMP
30 AMP
The 30AMP fuse in the engine compartment is the "main fuse" but it's not the only fuse that can bring your bike to a dead stop. I guess any fuse that blows and stops you in your tracks is at that point in time considered to be the main fuse.
