I am replacing the original 80 amp ferroresonant charger with a pronautic 60 amp charger. The shore power AC cable has the usual three wires, white, black, and green. However, while the green and white wires connect directly to the pronautic, the black wire wanders off into some unknown place and seems to reappear for attachment to the charger. I am not getting any Shore power to the charger. I want to trace the black wire. Can anyone tell me where that wire goes before it returns back to the charger. I am looking to see if there could be a blown fuse somewhere along its path.
 
To be installed correctly, the black should go to a 120v breaker somewhere on the boat.
The green should come in from shore power, go through your galvanic isolator, then the the bus bar where the charger should also go. The white could go directly to the charger I suppose, but really should go to the bus bar in the AC panel then over to the charger. There should also be a connection between the green and the DC negative on the boat as a bus jumper connection as well.

If you are not well versed in marine AC and DC wiring, I suggest you hire someone in to look things over. Incorrect installation can kill someone.
 
Paul is right on to have someone knowledgable look it over.
An issue older vessels have is you never know what someone may have changed. You need to verify where each wire goes to be certain it is wired correctly.

If not you could be putting current in the water around your boat, creating a risk of electric shock drowning.

Let's start with a simple question... Do other 110V items work properly on shore power? Depending on where that leads, we might circle back around to Paul's answer. But maybe you'll get lucky with a simple solution.
 
As I sat in the engine room with my feet in that little bit of water that's always present and my back against a cast-iron riser, staring at the hot 110v wire, I had an epiphany - went home and hired an electrician to handle the job. Better to live to fight another day.

I appreciated your comments.

Good call. By the way, we’d love to see some pictures of your boat at some point. We love the classics here.

Bad pic but gives you an idea (assuming it uploaded)

I thought I was the only member here with one of these crazy, old boats. This is our ‘84.

We love it and I’m looking to do a charger upgrade next season too.
