Does it try to turn over with the key, or are you pull starting? My 330 wouldn't do anything with the key, even though I had 12 volts at the battery. Turns out the quick connect at the kill switch/reverse override box was not making up. I unplugged it, cleaned out the the dirt, and plugged it back in. Now it works. I was stumped for about a week looking for inline fuses and the elusive circuit breaker kit before I stumbled across this quick fix.
