One of my Spa Gauges (OIL/FUEL PRESSURE ) flipped out, both read in the 240's. I use the pressure for the FASS and the temp for outside. My Mag trans pan does not have a place for the intended temp sensor. I Pulled off the connection, no change. What happened? Internal malfunction (bad gauge) or did the discobobulater crossfluxculator get crossed? :cool:

Thank you,
Jim

Most likely you have a bad/dirty connection to one of the senders or the molex plug on the back of the guage. My SPA's were very picky that way, I had the best luck with using a dielectric grease on all the connectors.

Hope this helps!

My Spa's internal light is screwing up again. Keps flickering
This is the third guage head now.
When the nexus guages come out this one is going in the junk pile.

I also have had the back light go out on 2 gauges.
SPA is fantastic about standing by their product.

You might also try a seperate ground on the senders. I had to do that to mine to keep the numbers from jumping around. No other prob in 45k mi.

your right about SPA being good with customer service but this is the 3rd head and I'm not going for # 4
