I have determined that the oil pressure gauge is Good. The water temp gauge is dead. The charge gauge is OK.
The fuel gauge however is driving me nuts. Initially the gauge showed empty all the time, despite removing the sender wire. The ignition wire is live when the ignition is on giving 12v.
Looking at the back, the ignition live wire however appeared to be on the wrong terminal, the red coloured one having the sender wire on. So I swapped them and now have a gauge that reads full immediately the ignition is switched on, irrespective of connecting a ground wire direct to the sender terminal.
Help!
I'm hoping that the full reading means that the gauge is OK, but if I'm honest I'm stumped!
Thanks in advance.

I am guessing that the ground is not getting through properly to the sending terminal. | | | | | Joined: Apr 2010 Posts: 24 New Guy | | New Guy Joined: Apr 2010 Posts: 24 | yup thats exactly what I'm saying.
As the gauge was wired up backwards, is there a chance that it is now burned out? I havent removed the cluster yet, but is there a way to inspect the gauge or is it just toast? | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | " . . .

Disconnect the sender terminal at the gauge post. Does the gauge still read full?

If it is a six volt gauge, both gauge and sender could be damaged. | | | | | Joined: Apr 2010 Posts: 24 New Guy | | New Guy Joined: Apr 2010 Posts: 24 | Ok thanks. Got one on order now. 12v that is  | | |
