What would cause a starter fuse to blow? It is 7.5 amps in the Advanced Control Module used with a Quick Build panel. It is the older model before they went to logical breakers. I flew yesterday, no problem. But today it wouldn't turn over. Turns out the starter fuse was blown. But why? I examined it and it looks kind of cheap and flimsy. I put in a new one and everything is working fine. Would excessive cranking to start a hot fuel injected engine blow the fuse? Does 7.5 amps sound right for the starter motor? I was thinking it would be a 10 or 20 amp fuse. What else might cause the fuse to blow. I have only 38 hours on the airplane, RV-7A. Thanks
