Just finished up with mine! Fell apart in my hands.

 

What was the reason you replaced yours? Mine isn't brittle like that it's fine just nothing works lol

 

My dash lights worked every so often but I needed them to work. So I bought all new stuff and did the job. The circuit board in stock form isn't quite perfect. One of the inner bulb holders when tightend properly doesn't make contact with the circuit board so you have to loosen it slightly. I only found this out after putting everything back together and only half the dash lights worked😀

 

Oh nice nothing at all on mine work so I'm trying to fix it all , do you know where the ground is for the cluster?

 

Well the circuit board connects to all gauges and also snaps onto the voltage stabilizer which is also on the backside of the cluster. Not sure as to the ground but I assume it is part of the main connector that plugs into the back of the cluster.

 

Everyone says check your grounds... Where are the grounds located????

 

How I would check the ground connection: Remove cluster, take a look at your plug. Look at location # 9 on the plug, it should have a black wire running to it. This is the cluster ground. Connect a continuity meter to one end of the # 9 terminal on the plug. Connect the other end to a clean metal surface on the dash, or run a wire to the - side of the battery. If you get a 0 reading, your ground for the cluster is good. No reading, you have ground problems. If you have ground problems, time to start tracing that black wire in the harness. Or cut & splice that black wire to a good ground, like clean metal on the dash. Since you have some dash lights working, I'd say your ground is most likely good.

Thinking about it, but without my wiring manuals to double check, I believe the gauges ground individually, thru the sending unit. Oil & water in the engine block, fuel back at the tank area on the frame.

Have you checked your fuses????

Have you removed the wire from the temp sending unit & run a wire from it to a good ground such as the - battery terminal?? Turn the key on & see if your temp gauge moves. If it does, sending unit is most likely bad.

 

hey guys, i'm looking for replacement gauge cluster for a 77 f150 custom can anyone point me in the right direction

 

If you have an 85 MPH speedo & gauges, here's one: 73 79 Ford Truck Bronco 85 MPH Speedo Gauge Cluster Tested Speedometer 77 78 | eBay

 

thank you mr scotts scott, I wonder if this will fit a 77 custom truck, mine has a blue circuit board.

 

Tim, does your present cluster have oil, amp & temp gauges, or just warning lights?? Cluster in the link has oil, amp & water gauges, & will not replace one with warning lights.

 

mr. scott mine does have temp and oil gauges but my circuit board numbers don't match , the numbers I have are D3TF10C956 on a blue board, thank you for your help

 

You are missing the two letter suffix of the board.

ID number: D3TF-10C956-AA = Ford part number: D3TZ-10K843-A .. Printed Circuit Board-Use with Oil/Amp Gauges / Obsolete

Applications: 1973/74 F100/350.

D6TZ-10K843-B .. Printed Circuit Board-Use with Oil/Amp GAUGES / Marked with ID number: D6TF-10C956-BA / Obsolete

Applications: 1976/79 F100/350; 1976/91 Econoline; 1978/79 Bronco.

E1PZ-10848-A .. Instrument Panel Cluster Back-Use with Oil/Amp GAUGES / Obsolete - Available NOS

Applications: 1981/91 Econoline, retrofit: 1976/79 F100/350; 1976/80 Econoline; 1978/79 Bronco.

This was the Ford "service part replacement" for the 1976/80 POS composition cluster back that can TURN TO DUST before your very eyes!

 

mr, number dummy.
you are correct I did leave out the letter suffix, the correct number is DT3F-10C956-AA
thank you for your help

 

Bigbluedent,
The ground you are looking for is directly forward of the gauge cluster. It should be a ring terminal screwed to a narrow vertical web of sheet metal, with a black wire leading from it. Mine was rusty, so I disassembled and cleaned it up. I posted this on the "Electrical Systems/Wiring" forum, it might help and it is a cheap fix (always nice)
