Temp and Battery gauge don't work

Working on a 1972 Cheyenne with factory tach and gauges. Temperature and Battery gauge are not working. Does this sound like the PC ? If so , is there an easy way to verify ? Thanks !

Dig up the wiring diagram on this site and follow it.
People babble nonsense about the battery gauge. It measures the difference between battery voltage and alternator voltage. More + battery, bad, more + alt good. No current is measured.
There are little inline fuses at the fender/gill intersections you might check.
Check the V input at bothe sides w/ the connector unplugged.

Thanks franken , inline fuses were blown , temperature gauge and wiring are good . When I ground the wire the gauge works . My guess is that someone has installed the wrong sending unit. Checked temperature with a infrared gun and that's all good . Thanks again !
