Rev Counter problems.
Posted: Fri Jun 24, 2022 4:44 pm
Hello
I have a 1991 Rover Metro 1.1L which has the 1.1 litre 8 valve K series with a carburettor.
I recently bought an instrument binnacle with a rev counter, and because mine has a rear windscreen wiper it has the wire from the coil already fitted so it should just work, according to the Metropower guide.
However, after plugging it in and starting the car I have discovered that when the engine is at idle (engine was cold so probably 5-600rpm) the rev counter was at 0 still. When you raise the revs the gauge does begin to work, but when it's at 1000rpm the engine is doing considerably more than this (probably 2000 or more).
Does anybody know what could be the cause of this?
Are they different on the fuel injected cars and, if so, would it cause a fault such as this?
Thanks,
Ryan.
