HELP: Headlight switch triggering STARTER!!!

Good progress. One negative though--the ammeter circuit is problematic enough without adding more. (problems) I would not use whatever those inline connectors are. I know it's a PITA to bolt the ammeter up when you pull/ replace the cluster, but that is the best way to do it, there is a LOT of power there

Make certain you disconnect battery ground. The ammeter circuit is NOT fused except the fuse link.......and it is poor protection
