Default Proper Ground

Is a t-top supposed to be grounded to negative side of battery?
Mine isn't.

Most are not. My tower was, just because I worry about lightning.

Technically every piece of metal on your boat should be attached to ground.

Hello, what is it you are trying t protect against? Lightning strikes? You can get a specific plate that goes under the boat for this, common on sail boats, I cant see parasitic corrosion being an issue, do you have a lot of wiring inside the tubes, like theyve been used as rigging tubes?

Here is SW Florida Lightning Strikes are a real danger, if all metal is not bonded and grounded to the earth(water) somehow you are a taking a great risk. In addition to full blown lighting strike you get small discharges than can cause damage and shock on your vessel if all is not properly bonded and grounded.

My question was born out of surprise really. I was checking fuses (nav lights inoperative) and attached my test light to the t-top when I found it wasn't grounded. That just seems odd to me.
