Just got finished converting my N to the 12 v and i took it for a drive around he yard when al off a sudden a small fire broke out on the wiring harness and smoke came bilowing out. I turned the key off and ran like a bat out of hell for an extinguisher. By the time I got there the wires melted and the fire went out. I had notice the ammeter was acting funny. I’m thinking he ammeter shorted out but the harness meted right next to a spark plug as well so either the spark plug shorted the harness or the ammeter. Just wondering if I need a new ammeter or not? Definitely going to make some brackets on the head to tie the harness up to
