Gauges not working

[72step]

I got an 85 chevy k10 that was somewhat back together after a restoration and the vitals gauges i cant get working. Fuel gauge and speedo work fine.

Use a test light on the voltmeter gauge, if power is running to it, and you have a ground, your guage is likely broken. Make sure the Engine temp guage is grounded and the wire runs to the temp sending unit. I don't remember how the oil pressure guage works on these, so you may have to take a look at some wiring diagrams. While you look at wiring diagrams, make sure everything is in the correct place, and once again verify everything is grounded. It can get frustrating, but be patient these old trucks are simple enough.
