"Jeff, I think our boats must
"Jeff, I think our boats must have some weird telekinetic connection. We seem to be having similar issues. After resolving my intake manifold issue (that's working very well by the way), my alternator output voltage has been creeping up. It had been running 13.7 or 13.8 volts, I noticed 13.9 a few times and this last week, 14.0 and 14.1. The analog gauge on the dash, the digital voltage output on my depth sounder, and a digital hand-held multimeter all give the same reading, so I think it's accurate. I had replaced my alternator with a 1 wire, internally regulated alternator in 2004, when I acquired the boat. As I recall the price was only slightly higher to replace it vs. rebuilding. Depending on the backlog, rebuilding might take longer, and it may not be worth the wait for the small savings. I'm going to pull mine Sunday and have it tested by an alternator shop on Monday. I'll let you know where this goes. Search this forum for voltage regulator. there is a lot more info out there.
Best,
Chuck"
