Somehow my tachometer is stuck at around 3000rpms...and im not sure how to fix it..ive heard there is something like a voltage regulator...but im not sure where this is located....any ideas?

your voltage regulator most likely is internal in your alt. i suggest starting with tapping on the instrument cluster. mine gets stuck on 4k sometimes and then i tap it and it goes back to normal. if it doesnt work from there you might have to look at your sensors or replacing the cluster or just the tach

dont mean to steal this thread but where does the rpm get its signal from. using the stock wiring harness
