Im really enjoying this forum. Helping me understand the new project. So here it is...I have a 1987 Bronco with a 351w installed. None of my gauges work except the speedometer. Can anybody help explain whats going on. How the **** does the dash come out?

Check your fuses and your grounds.

I love this thread about guages and shorts or lack of grounds...

I suspect that the location of the grounds for an '87 are similar.

Here is a list of grounds for a '92 - '96 bronc

The Haynes manual lists 10 separate grounds... A-J.

A. Starter mounting bolt

B. Right front of Engine compartment near the battery

C. Lower left front of engine

D. Right front of engine compartment on upper radiator support.

E. Left front of engine compartment Upper radiator support

F. Bottom of cowl panel

G. Rear of left fender apron

H. Behind bottom of right cowl panel

I. Left rear corner of cargo area near rear lamp assembly

J. Under center rear of vehicle on rear cross member.

BTW... welcome to BroncoZone!

Ok so the gauges are getting power because when I turn the key they adjust but fall to empty. The gauges I am talking about are the fuel, battery, oil, and water. Could this be sending units or another problem? Im trying to rule out sending units since it seems funny that NONE of them work.
