This is really covers a few areas,
1) connections to my hull
is a British build from 1990 so when new it came NOT up to ABYC standards. And there have been about 7 previous owners making modifications. Aside from the inverter
, there is no other AC power. I took out the original shore power
. Also there is no bonding on any of the through hulls so they are all independent of each other.
I changed my hull
anode this year. This is the first time since I've had this boat
. Attached to it were wires from:
arch (w/ solar)
auto pilot quadrant
It seems to make sense to me that the packing gland
and the quadrant are connected to protect them. But the arch has solar panels
(12v) grounded to it and the inverter has the chassis ground which I would assume is 120v ground (and I will be upgrading that wire to the appropriate size).
To confuse me more, I've read and I saw on the electrical
diagram (from original specs) the engine
should also be connected to the anode. But I've also read that there should only be 1 ground for 12v. The engine is the 12v ground through the shaft/prop. The coupling for the shaft is not a flexible one, it's directly bolted so there is a good ground.
So back to my questions.
Should the arch be connected to the engine (terminal block) instead of the anode?
What about the inverter? Is that a 120v ground or is that ground for 12v ? I ask because the inverter has both 12 and 120v. Should that also go to the engine?
Should the engine be connected to the anode?
