Sorry I meant Amp meter....What does the documentation for the altimeter say to hook it to? A US '78 FJ40 does not come from the factory with an altimeter and there are no provisions for one in the wiring diagrams.
Perfect! This is what I needed!This is how my 1976 is wired. Best pic that I have.View attachment 2511525
It could be the fusible link, did you test it? You realize that when you say it's not working and the needle isn't moving doesn't mean anything. What are the conditions the vehicle is in i.e. are the lights on, engine running, key turned on engine not running etc.? Do not assume that we know what you are talking about. With electrical you have to be concise and accurate in your description of the problem for an accurate answer, or else you will get inaccurate suggestions. Once again do you have a wiring diagram?Ok got it all back together but when I turn on FJ the ammeter is not working...needle not moving. What could be wrong now...could it be the fuseable link?
Ok here is more detail. Everything is on...during day lights off at night lights on...heater on and off...yes I have a diagram from Haynes manual. I see in the diagram a fuseable link...can’t locate.It could be the fusible link, did you test it? You realize that when you say it's not working and the needle isn't moving doesn't mean anything.

The two smaller red wires coming off of the battery should both have a fusible link in them. Since your electrical system is working the fusible links probably have been removed and not replaced. Go to @Coolerman and order a replacement and some correct color wire to replace those red wires. There really should only be one smaller wire but who knows what wizardry has been done to the wiring. You can choose to go without the fusible links but when your vehicle burns to the ground look in the mirror for the person responsible.
With the engine off and the headlights on you should see the ammeter needle deflect to the left. If it deflects to the right your wiring is reversed. Turn the headlights off, start the engine and the ammeter needle should deflect to the right. If it is not moving at all it is a good indication that it is inop, if you have the correct wires attached to it. It seems you do have the correct wires attached as the lights work. Remember to always disconnect the battery cable when removing or installin the instrument cluster. They are expensive and getting exceedingly rare to find when you need to replace it.
What does the largest wire on the positive terminal go to?
Fusible link protects the wire between the battery and the fuse panel.Ok got it all back together but when I turn on FJ the ammeter is not working...needle not moving. What could be wrong now...could it be the fuseable link?
