Garmin GPS will not turn on

My Garmin GPS 128 worked fine for over 10 years but now it will not turn on. There is 12vdc to it and the fuse is not blown. There are three dead ants inside the display screen but they have been there for years. It is mounted inside the boat and there is no apparent water intrusion. Any ideas?

Well, yeah. It's 10-year-old electronics that have been living in a harsh environment and they finally gave up the ghost. It happens. It happened to me this spring. I had a 30-year-old Beckman Industrial DMM that just up and stopped working while I was in the middle of checking my mast wiring just prior to stepping the mast. Meter's never been abused. Almost looks like the day I bought it. (I take care of my stuff.) Fuse wasn't blown. There was no power present, in fact, other than what the meter supplies. It just... died.

I would probably try to take it apart to see if there's anything obviously awry, but I've got the tools to work on the small electronics you'll encounter inside (magnifying-glass-headband, grounded-tip temperature-controlled soldering station, etc.) and the experience to do so. Unless I spotted something blatantly obvious, I'd consign it to the electronics recycler and replace it.

The problem was corrosion on the multipin connector. Who woudda thought-corrosion on a 12 volt system. Works fine now maybe for another 10 years. Some day I'll get the ants out.

Ah. When you wrote "There is 12vdc to it...," I incorrectly assumed that meant "to the unit."

Why not? Those connector pins are metal.

Or perhaps longer if you occasionally treat those connectors with DeOxIt and ProGold

Glad you got it working.
