I've witnessed this with an optical tachometer on a boat. a 2 to 1 pulley ratio was reading as if it were a 1.5 to 1 at 1200 rpm but was 2:1 at idle
A slipping belt would most easily explain this symptom, but do always find and clean the grounds wherever you find them | | | Re: Headlights dim when on the gas pedal. | Joined: Jul 2019 Posts: 11,241 Likes: 411 Post Junkie | Post Junkie Joined: Jul 2019 Posts: 11,241 Likes: 411 | I agree with Rusty. I bet it's a ground. All good advice though. | | |
