Re: 200 merc /carbs, won't start/gauges die
I had that same problem about 3 months ago, the pins shorted/arced and burnt inside the harness plug. We ended up eliminating the wiring plug and wired direct. Mercury wanted about $350 for the harnesses. Took less than 2 hours to make the repair. I guess I will worry about the wires if and when I should ever have to pull the engine.
