  • Volt Gauge

    Hey All,

    Have not been on TT much the last several months. Volt gauge suddenly went to zero last weekend. Made it back just fine but the battery is new this year. Am travelling and have not had a chance to check the alternator. Any intial suspicians on whether the alternator, cables, or gauge are the most likely culprit?

    I have been searching the forums but was unable to find an answer.

    Thanks in advance.

    I would suspect that it's a bad ground on the gauge somewhere... It's the simplest gauge, it just reads the hot vs ground, that's it. If it went to zero and the boat still ran, it's not the battery. If your alternator (or regulator) were bad, you would slowly see the volt gauge go down to zero. When it gets below about 5v, you would notice that it's not running properly, especially at idle.

    Did you try to start it again when you were back at the ramp? That's a good way to tell - if there's enough juice to crank it over, you know it's either a gauge ground or the gauge itself.

        Happy to help (or at least offer my two cents...)

        If I ever have the chance, I'll take you up on that offer for sure!
