tachometer not working properly,i had a broken rectifier i have replaced with new one, i have 12 volts going to my tacho but soon as i start my engine the tacho goes straight to 3500 rpm, i have the dial on the back set at "6" which is what i understand from so much research i have done its suppose to be also with positive , negative, pulse grey wire connected to the say buzz board where rectifier wires connect i am still getting the same results of the tacho jumping to 3500 rpm and staying there even when its at idle or full rpm i have been trying this out for like 4 weeks and still got this same problem all help would be greatly appreciated. Thank You Peter
