Hello. I'm new to the forum, can anyone tell me how big the gas tank is on a 96 sea nymph SC170? I just bought it and the gauge doesn't work so before I go about the trouble of finding out the hard way I just thought Id try and ask, doesn't hurt.
If you gauge doesn't work its easy enough to figure out if the issue is either power, gauge or sender.
Check for 12V at the gauge with the key ON.
If no 12V look for a bad connection or blown fuse
If you have 12V connect a jumper to the S connection (should be a pink wire) to ground. Grounding the S terminal should cause the gauge to peg full.
If gauge does not peg you probably need a gauge
If gauge does peg, go to the tank sender and ground the pink wire at the tank, gauge should peg again.
If it does not peg check or replace the pink wire.
If it does not peg its your sender
