• Engine kill switch blows Seatalk bus fuse?
  • Sounds like you engine alternator is causing a spike through your system. The Seatalk is just "sensitive" to the spike.
  • Maybe...
  • The bottom line is that current
    • I was thinking along those lines, but...
      • I understand what you are saying but
        • Makes sense to me. Spring launch and electrical corrosion go hand in hand.
        • I gotta see a picture of it.. here's a try
          • Extrapolating a bit more on this idea
            • Not that simple
              • The TACH is connected directly to the Alternator...
                • Well yes but no. Sure sounds like I deserve a GOBI award though.
                  • Then take the ground to the Seatalk
                    • It's already direct to the battery
                      • With NOTHING else connected to it?
                        • I'm not going to mess with the main panel
                          • I was suggesting going to the Seatalk...Not the panel.
                            • Would try that if the hour-meter rewire doesn't do the trick
          • I'm with you Charlie. Here's what the mechanic said:
            • Ahh, that explanation seems to make sense.
    • It soundlike a transient -- not continuous isse, Steve
      • That's what I was thinking a surge that should be surpressed....
  • How about a fuel shutoff cable? Works without any possible failure.
  • the hour-meter rewire did the trick
    • So the "What Changed?" troubleshooting question pointed to the solution... congrats!
    • BTW, where is that old GOBI award image? Dave Gibson???
      • Ah yes, the adjustable wrench with the 90 deg twist. Remember it well.
  • Kill switch saga continues. Any electrical wizards reading?
    • If your ohm meter is accurate...
      • The high co$t of green paint
    • I haven't read the whole thread but do you have a clamp on ammeter?
      • Could this be a symptom of a bad ground connection to the battery?
        • Found it!
          • Good detective work...
            • Thanks. I found a good guide for testing alternators on Fluke's site
