Quicksilver Fuel Gauge

[delitubby]

Hi
My RIB has a fault with it's electronic fuel gauge.
I filled the tank and i noticed the dial, when we were underway, jumping sharply from the 4/4 full mark to 1/2 then back to 4/4.
It then stopped working.
The gauge is a Quicksilver (think the p/n is 835356 lettering worn)
There is a 12v supply to both "S" and "I" terminals and the ground is fine.
There is a an "L" terminal but that has no supply to it and i can't see a connector that may have become detached so i guess it's not needed?? but when i do connect a 12v source to the "L" it goes straight to 4/4 (tank is prob 7/8ths full)
I'd really appreciate advice / views on this and also if anyone knows a web address for quicksilver i'd appreciate it as i can't find them.
Thanks

Something similar happened to mine. It wasn't the gauge at fault, but the sender in the tank. The float had fallen off the arm so it wouldn't send the reading.

Prob just as likely the sender as the gauge.

Quicksilver parts need to ordered through a Mercury dealer, one dealer that does do online sales is http://www.ribsmarineparts.co.uk

Looks like it's time to strip out the sender then!!
Thanks for the advice chaps!!
