The guy I bought it from said it had done it once time to him also. I never had any trouble with it last season, but after it sat this last winter it started popping them like mad once I fired it up this year. Never while it's running but only on start up before the engine even turns over. I don't know how to read a schematic. Could it be possible that the 10 amp and 15 amp fuse got switched around? How can I determine what the correct position for them is? The way they are in now, the 10 amp fuse is closer to the front and the 15 amp is nearer the back. Thanks in advance. And just out of curiosity, what is the worst case scenario if I put foil on it? It has a tiny little 12 volt battery. The amount of electricity doesn't seem large enough to do any damage. This is why foreign made stuff is kicking our ***. Not even 100 hours and already a GD electrical prob. Ridic.
