The tach works off of the distributor.
yes
There are several things that can cause your engine to misfire and the tachometer to not work properly. The most common cause is a malfunctioning vacuum hose.
In a 1987 El Camino, the tachometer is generally designed to work with the engine's specific configuration. While both the 6-cylinder and 8-cylinder models may use similar housing and appearance for the tach, the calibration of the tachometer differs. The 6-cylinder engine typically has a different RPM range compared to the 8-cylinder, so the tachometer readings may not be accurate if swapped between the two. It's best to use a tachometer specifically calibrated for the engine type to ensure proper readings.
Yes, however, the six cyl tach is different from the eight cyl tach. It will work but the RPM display is wrong.
The Mazda tachometer and the speedometer have separate cables. The tachometer cable probably does not work properly. Change the tachometer cable.
it sure would work.. behind the dashboard are plugs for each function. one for tachometer, one for speedometer, fuel, water temp. ect.. if your new dash doesn't have a tachometer it will not interfere with the speedomet aspect of it. but you will not have a tach obviously. that sucks kid
One possibility is that the tachometer connections to the circuit board of the cluster have become corroded. It is also possible that the tachometer has just become worn out and needs to be replaced.
yes it will, they are the same frames.
it would work on a 65 el camino but I don't know on a regular chevelle, if the wheel base is the same it will work.
because they are broken.
rev counter not working
Yes, 1968-1972 had the same frames.
