Instrument Cluster

[1979 FJ40ish]

I have always believed this was the original instrument cluster for my 1979 FJ40. My AMP gauge stopped working recently, which got me looking for a cause and a cure. As a result, I discovered the YouTube videos on the 10mm Garage site and that got me looking at my cluster more closely.

Do you think this is the original cluster or a later replacement? Note the dual speed indicator MPH & LM/H and the 50/50 AMP guage.

That’s what my 5/79 40 has.

Looks correct … gauges do go bad … why do you think it went bad?

 

[JohnnyC]

Had my charge wire off alternator burn out at connector in harness … gauge wouldn’t move

If that’s your case… check your wiring

My 79 looks the same as well.

Have you checked out your fusible link? Acting as a shunt, between alternator and battery, the small voltage drop across it (charging or discharging) moves the ammeter needle, or is supposed to anyway.

But, you'll also want to check the other connections in the ammeter circuit, including the two lines between fusible link and the ammeter.
