Short in my analog gauges!!!!!!!

[Almajordad]

I have a 2016 Sylvan Pontoon, with a 2016 Mecury Marine 150 4 stroke engine! My engine is a real champ! Runs great! The problem is my gauges, Sometimes they all work and sometimes they don’t! All my fuses are all good! These gauges are a mystery! I need help!!!!!!!

Right off the top of my head, check your ground on each wacky gauge.

Gauges need ground, power and some kind of sender. Power and ground are common to all gauges, If more than one malfunctions, suspect power and/or ground. Likely all gauges are powered by one small amp rated fuse.

Start looking for the loose/corroded common power or ground connection.
