Air Conditioner , Tachometer & windshield wipers Dead - Fuses?

I have a 1995 NAS D90.

My Tacho, and my AirCon both went dead. I don't know if they went out at the same time or not. I have checked all the fuses inside the cab.

Is there another fuse box related to these that I do not know about? Could it be a relay issue (if so which are they and how are they tested?)

Any advice or additional help or resources?

Thanks

Don't remember if the 95 did, but if you still have the round glass fuses test each side with a rest light and fix the connections if they are not providing continuity.

My Aussie 110 has the AC fuses in the battery box. [emoji2371]
Thank - as far as I know there are two fuse boxes the one in the cab that has almost all of the fuses and the one in the engine compartment that has the 3 larger 55/60amp fuses…


So I double checked all the fuses and nothing seems to help… According the the label on the inside of my diesel cover fuse #5 should be the tac, however it’s also supposed to be the turn signal and that IS working.

I think 5 is your gas gauge—looks that way from wiring diagram. Don’t think tach is fused, at least not on diagram. Check white/Black wire coming off coil. That I believe is tach signal. At least on NAS ‘94. Don’t think it’s related to air con. I’ll dig a little in the wiring diagram

Yes - I totally forgot to write in my initial post that the Wipers were dead too.

I’ll check the alternator wire this weekend - thanks

All of the gauges have a ground that go into a connector. Check there. Some of the grounds go into the firewall and are connected to a ring terminal in the center top of the bulkhead inside of the engine compartment. I inserted new Ground wires to a better ground and ground at the body in a better fashion to the chassis and the battery. The grounding on these things is terrible. Check all of that, there is a link in the last few posts of new posts about PDF manuals. Look in there for the electrical diagram

Will do, how do I access the gauges? Are there any instructions on that?

Any chance someone has a photo of where that is, what that looks like?
