Electrical Clean Up

I was too exhausted after ripping wiring and various other components out of my boat to take any pictures.
I will snap some pictures of all the stuff on my next visit.
In a nutshell. Nothing seemed to work right. The Amp Hr Meter, the Three Stage Voltage Regulator, the isolator and alternator sensor. To cap things off my batteries were not charging at the same rate and my starting battery was discharging while I was away from the boat.
Turns out that by battery bank two was toast. After much experimentation and ripping things apart I discovered that whoever installed the new Yanmar engine did not make any effort to integrate with the existing electrical system. The system was charging using the internal regulator in the alternator and not the 3 stage external regulator. The starter was wired directly to the starting battery with no switch. The rest of the switching arrangement doesn't seem to make much sense. Anyways after two days of hard work I have an enormous pile of surplus wiring, electrical components and battery cable lying in my cockpit.
Miraculously I have the system up and running adequately. I have a good 8d battery as a bank and a good starter battery, things are charging adequately and there is a switching arrangement I can understand.
The boat is about 200 pounds lighter.

I have a new alternator regulator kit ordered.
I am in the process of obtaining four trojan 6 volt batteries which will be my house bank.

I will install all that when we get back from our July sailing trip.

Oh and the electrical clean up will also continue when I get back. I suspect there are still a few miles of wiring that doesn't do anything.
