Mike, it's highly unusual for ALL the gauges to go bad -usually it is just the Proofmeter. How did you determine they were bad? Do you have all of the Essential Manuals for your NAA? There is but a single wire and light socket on the dash panel. AMMETER uses two screw wire terminals and all others are mechanical devices so no electrical connections made. You said yourself, you have a new tractor "...that needs a lot of work." Does the engine start? Your wiring could be all mucked up, 90% of all non-starting issues, and thus you won't see a charge on the AMMETER. Is it 6V/POS GRN or a 12V/NEG GRN setup? Oil Pressure Gauge is a mechanical device. You won't see a reading unless engine is running. Proofmeter also is mechanical and engine must be running. New parts can be purchased at Dennis Carpenter and/or JUST8Ns -see LINK. Manuals are a must-have tool for your shop.
