Prosport Electronic Boost gauge failing

[aidanair]

So I have an odd problem. I have this in my A pillar.
http://prosportgauges.com/amber-white-6 ... gauge.aspx

It used to work well, but now it has been malfunctioning. Thanks to a volt meter built into my turbo timer, I have noticed that the gauge only reads when the voltage is around 12-13 volts. When under load, my power circuit is charged to about 14.3 typically, and as soon as the voltage gets to like 13.5+ the needle just dies and it stops reading. Whenever my alternator is failing which unfortunately happens often and my car is only generating 12 -13 volts, the gauge works perfectly. Any ideas? Should I just put a resistor between the sender and the gauge?

However, I also noticed there's a LOT of discussion online about this particular unit having issues... Searched Google with "Prosport Electronic Boost gauge problem voltage". That oughta get you started.

Good luck buddy!

I actually just worked on a vw with that gauge and the oil pressure gauge from them, they werent reading right before and we couldn't get them reading correctly even after running all new wiring, just reads max or nothing at all. Not a very good product in my opinion.
