temperature gauge on my Westerbeke
7.8 BDT stopped functioning. I figured it had to one of two things, the gauge or the sender unit. Replace the gauge first (easiest to get to) and that didn't do it. Next I replaced the water
temp sender unit, the single
wire one because I think the two wire sender is the auto cut off when it gets too hot. That didn't do it either. Now I am stumped. Should there be a voltage on the single
wire between the sender and the gauge? Any other suggestions? Gen sets is running fine, just not registering the water temp.
