It should be a yellowwire on the igniton coil
Astra 1.7 cdti wont rev past 300 rpm
The tach should have 3 wires a 12v accessory, ground, and rpm wire. The rpm wire is the blue one on the distributor.
sounds like a dead short in the tach wire, trace the tach wire and see if it the wire insulation has been broken.
it sounds like a wire is not connected or is shorted.
follow the instructions, if you have no instructions then ussualy one wire to negative side of coil and the other wire goes to ground.
car audio I need to know the rpm color wairring for Chrysler 300c
Get an RPM meter (tachometer) for 1 cylinder 4 stroke engine to match with your engine. Connect ground wire from RPM to body, usually black colored wire. Connect power wire to ignition switch, make sure it is connected to 'ON' position of switch, this wire usually with yellow insulation. Connect green wire to coil negative terminal, this terminal is connected to contact point or ignition trigger system, the wire from tachometer is usually with green insulation. Start your engine and check RPM reading.
The RPM normally increases as you push the race pedal in your VW. However, it is possible that the wire for RPM might be broken, causing it to suddenly increase without race.
be glad it dosent hop...........might be a loose wire.........
Motor mount, Spark plugs, Spark plug wire
i find the rpm wire on speedometer,still not find the speed wire. but i hv a airflow control dunno how to install....
