Thanks guys. The wiring is all factory as I bought the boat almost new in 2004. It had 30 hours on it. I will start with the individual connections and if that doesn't solve the problem go to the big plug. Or should I start with the big plug first?

When you guys say "tinned" what exactly does that mean? My impression is that the connection is covered with solder. Is that correct?

Piemma,

When the copper wire is manufactured the last step before the insulation is the copper is coated with a thin layer of tin for corrosion resistance as to not turn green and oxidize. Good connectors are tin coated too over time this may wear and turn green. Real good plugs have gold plated pins, like on your fishfinder.

If your loosing all those gauges recently I'd head right towards the big plug.
