Hello, I'm hoping someone can help as I'm at the end of my rope here. My dash goes haywire at around 7k to 8k rpms. I get a flash of the yellow engine light and the dash does dark then lights back up and the speedo reads 0. When I bring my speed down to under 15 miles per hour it starts to work agian.

All this started after I changed the stator rectifier and spark plugs. I wentered back and checked all connectors and they all were fine.
