Who makes their gauges?? Are they only sold by nordic?? My tach is kind of screwy and the oil pressure gauge only reads around 40-45 psi when I know for a fact I'm running 75 psi.... Thanks.

I know mine are made by Gaffrig which were made by Livorsi. Did you put another gauge on it? Usually its just the sender that is screwy, not necessarily the gauge itself.

Mine are Livorsi gauges from factory.

Are the sending units gauge specific or will any work??

Gonna be specific. Need a sender with the proper ohm range for the gauge. I would contact livorsi about the sender. Usually comes with the gauge set.

I have had my oil pressure and water temp gauges read "0" and it turned out to be the digital to analog converter that was mounted to the front of the starboard fuel tank. I moved them to the front dash area so that I could reach them without removing the back seat and the side panel..This is on a 2007 heat

I have the same problem with the converter once in awhile. When I start it up all gauges will be reading funny with my trim guage bouncing and RPMs off. Looks crazy. All I have to do is turn it off and restart. This happens about once a year... Maybe twice. Talked to the factory about it and they said it was the digital to analog converter.

What does the converter look like?? I didn't see anything when I had the side panels off....

I have no idea what it looks like. I was just told by the factory what causes the issue. It rarely happens but when it does you will know. My trim guage bounces like a kangaroo!

Yey for mechanical trim gauge lol.
