What color is the tach wire on 1993 ford F150 302 V8?
at the tach it is white-pink green at coil
At the dist there should be one to power the dist. & one for tach signal. Unplug one & see if car starts or if tach still works. Can't really remember for sure as its been a while lol. My 1972 tach wire is brown and it has a inline fuse from the factory. Your tach wire will be connected to the negative side of your terminal witch is labeled "tach".
What do you need to do to get your charging system to work after installing a instrument cluster with tach in a 1993 Ford F150 5.0L?
They might have a different internal voltage regulator that is used.The idiot light in some systems acts as a resistance that makes the regulator to charge.try putting a small automotive bulb in series with regulator connection at the alternator and see if your gague reads any voltage then.Check a motor manual to define the correct connection post.
Yes, i found the answer. Truck had an aftermarket tachometer installed. 2nd truck this tach has been on. After 320,000 mi. on this tach, something in the wiring or internals failed. Unplugged the tach, truck fired right up. Check those aftermarket accessories you installed, before finding fault with the factory stock vehicle.
