Hi , Im Having Trouble With My 1984 F150 Auto Transmission 302 Carb Engine . Sometimes When I Start The Truck Guages For Oil And Fuel Does Not Work (needles Does Not Move) When I Turn The Truck Off And Start It Again Guages Suddenly Starts Working Again. What Is The Steps I Need To Follow To Find The Problem, ? Thanks In Advance Jesse

 

I'd suggest fiddling with the ignition key switch - moving it forward or back just a bit - to see if that fixes your problem. When the gauges don't work, do the radio & heater fan & wipers also not work? Or is it JUST the gauges that don't work?

The ignition switch problem is a common one. If wiggling the key does not fix the problem, then I would suspect the guage regulator that is mounted on the circuit board of the cluster.

ICVR: Instrument Cluster Voltage Regulator

 

Thanks For Mentioning That Chris (ctubutis) Fuses Keeps Burning , They Are For The Stop Lights And Wipers. I Should Have Mention This On My First Post. Thanks In Advance

 

I think it might be a connection problem with the switch as well......

 

The common problem with the switch I have seen on several of these trucks is the spring detent is not strong enough, especially in cold weather. It will not return from springing it over to start, and a light wiggle with your hand will usually bring it to the correct run position. When it happened to me, the first thing I noticed was the blower motor and the wipers would not work.

 

thats exactly what is happenning to me franklin2
