Ballast sending tanks expected to go bad?

[biacs]

Hi All,
Question on my 2006 SANTE :-)
Was using my ballast tanks last night and noticed idling around my two older ballast sending units were going empty and then back up to full occasionally.

The sending unit expected to just start acting flaky after a certain amount of years? ….and they should just be replaced when they spaz out back-and-forth.

The boat wasn’t moving and the tanks weren’t splashing but you could see the needles go up and down up and down on those older sending units.

Good enough for the season but just wanted to know if I should expect to swap them out over the winter. At least I won’t have to pull the gas tank for those :-)

I would bet that's a wiring issue somewhere between the sending unit and the gauge. I have never known the sending unit to act like that. I will caution you not to stand on your tanks though. That can bend the sending unit and cause issues.

Hey Jeff,
When I was doing my steering cable I was laying tap dancing what have you last year lol.

So I'm not sure how are you indicate standing on the tank can affect the sending unit. Just curious? I'm usually missing the obvious though :-)

Standing on the tanks can compress them, causing the rods of the sending units to hit the bottom of the tank, and bending the rod. This causes the float to get hung up on the rod, making the sending unit useless.
