Glad you had a good trip Dennis and sorry about the batteries. Thanks for sharing the lesson. I just checked the water in mine (for the first time) last weekend. They were full despite being several years old. Loads and usage on my boat are pretty light.

After we returned to boat from a nice dinner, we smelled a weird odor in the boat. Only in the main cabin. Could not locate source until next morning. Dinner may have had effect on investigative skills.
> The odor had a sulfide smell. Duh! Ruling out some sort of iron eating bacteria in the bilge I thought "where is only source of sulfur/sulfate/sulfide on the boat?" Batteries, of course.

Even grounded it on the back of the panel to further eliminate the wire. No movement. (As an engine temp sensor heats up, the resistance decreases. Grounding the sensor wire simulates high temp condition. The needle should deflect to max.)
