I've been having intermittent problems with the Tach, AC, and Alternator not charging on my '94--, I had my alternator checked and was told it is charging like it should.... Any ideas? Thanks

 

Definately start looking at the crank sensor! Either out of adjustment or needs replaced. Also I think there have been some problems with the wires getting chaffed too. It would be the first place I'd look!

 

Every time the ignition switch is turned on and before the starter is engaged you can hear a loud clicking sound . The sound is coming from the radio, even with the radio in the off mode. When the radio is turned on the clicking sound is heard briefly again. This is along with the problems in my previous thread. The truck has 140,000 on it. We are checking on the Engine Speed Sensor wiring and gap. Thanks

 

The problem was the crank sensor. Thanks
