Question about 1988 Ford Mustang
Hi i ave 88 mustang manuel tranny problem is my speedometer is flucuating and cruise control is making up its own mind and about the sametime my voltage on the panel was dropping slowly for about a week.. my amp light goes on when i start the car and goes off when i boost the rpm and goes back on when is on idle.. Is the speed sensor able to mess around with the voltage gauge..... no problem starting.multimeter red 12 volts on battery and 12 when startedand running..u think if i change the sensor it will change the voltage on my gauge......help would be great
Lets do this ck voltage with voltmeter at battery post on the back of you alternator. you have to have at least 12.35 volt at least. most likely around 14.-16.. but 12.35 min. any lower replace.
