Oil Temp. / Oil Pressure Gauges Stopped Working (WITH PICTURES!)
 
4 Attachment(s)
So my aftermarket Oil Temp. and Oil Pressure Gauges by Auto Meter stopped working all of a sudden and I have no idea why. Can you figure out what might be wrong?

2 Blue Wires near the Oil filter.
1 Red Wire in the fusebox.
1 Blue Wire inside the panel on the underside of the dashboard.

1st wire:
Attachment 450535

2nd wire:
Attachment 450536

Wire attached to fusebox:
Attachment 450537

Blue wire in driverside underside dashboard:
Attachment 450538

"Invalid attachment".

Derp.

Edit: Ah, there they are.
Your wiring is confusing.
I'll assume the two blue wires in the bay come directly from the gauges and the poorly tapped wire in the fusebox is supposed to provide +12v (apparently, full time) to same and wire #4 looks like a common ground for something.

What does the wiring at the gauges themselves look like?

Edited it for the pics to show up. Should show up soon.

If both stopped working at the same time, the problem is bound to be related to how you're powering them. In other words, I wouldn't worry about the sender wires in this case. Whip out a multimeter, and probe the +/- wires at the back of the gauges.

so both gauges are powered by that one wire going to the fuse box??? With no fuse??

I guess so. That's how I bought it from the previous owner which I think put them on.

I would check to see if power is coming from that fuse slot, then do a continuity test on the red wire from teh fuse box to the power wire on both gauges. If it fails continuity, you have a short in that red wire. Check for continuity for the ground also.
