I could really use some feedback. I bought a CX500 Custom with rear turn indicators that simultaneously flashed weakly when switch to the right or left positions. All grounds checked out. The former owner had a 5A fuse in the main fuse. I replaced it with a 30A and it blew when I turned the key to the ACC position. The engine started, but the problem remained. I left the engine running and replaced the fuse. I then heard a crackle near one of the spark units. Now, the engine won't start. I don't have the necessary test equipment, but suspect I may have caused or expedited the fatality of one of the spark units. Recommendations?
