Loose Bonding wire
« on: December 01, 2022, 02:39:59 PM »
I found this loose bonding stud the other day. It's in the bilge near the engine raw water through hull. The stud just pulls right out. It may have broke away from something buried in the fiberglass like a bonding strip of some sort.  The other end of the wire is attached to the engine. I replaced the seacock a few years ago and am pretty sure it wasn't connected to this wire. I'm not sure how to fix this. I've attached pics.

Well, sort of. It's portside wall of the bilge above the keel looking to stern.

Look at all the metal items in bilge and insure they are bonded. This may be the engine water inlet bonding lug. Pearson bonded every through hull. They even bonded my plastic through hull to the anchor locker above the water line.

Is it safe to assume there is nothing inside the bilge wall that that stud was specifically screwed to that needed to be bonded?  I'm thinking that stud is there as a means to attach a jumper wire to the through hull ball valve a few inches from it.  What's the best way to attach the wire to the valve without removing the valve?  I've attached a picture that I thought I had attached earlier.

Is there a bonding wire attached to it from the inside of the bilge?

That stud is there to keep the oblong inlet strainer located fore and aft and also as a convenient place for bonding wire.

The stud is the original Bronze? If so I'd source two bronze nuts to fit and run one up against the hull a little tight then the wire's terminal then the second nut against the terminal.

Resist the temptation to install washers unless they are also the same metal material as the stud which was originally the same as the through hull fitting- Bronze.

The terminal is silver but it is plated copper so it should last another 40 years- especially in fresh water sailing.

I had replaced the valve, through hull and strainer a few years ago. That stud must have detached from the strainer some time ago. I should be able to simply extend that wire over to my valve to accomplish the same bonding.
