Thanks everyone for these suggestions, but I canít say I understand them all.
I should have mentioned: Iíve been restoring the boat in Titusville marina for three years, nearly always on shore power
, and only just begun to look closely at the batteries and wiring
setup. It was pretty much like this when I got it, and I havenít changed it much except to introduce the windlass battery. It didnít have an electric winch
and my new Maxwell
didnít work very powerfully due to the long run, now it fairly sizzles.
Can I ask these follow up questions?
The alternator output should run direct to a battery--otherwise you may fry it if someone plays with the switches while the engine is running.
I understand this can happen, but the alternator output is always connected to the windlass battery via Ďbothí on the bottom switchóisnít it?
The forward battery keeps both starter solenoids energized regardless of switch position--not a good idea.
Arenít solenoids energized all the time anyway? Or do you mean that Iíve got two on the same line?
Keep the windlass battery completely separate, charge with either an echo charger or a small battery charger powered through the inverter.
I was actually thinking of buying
another big 12 volt battery and making it a dedicated engine start. (I have a space right next to the engine where the lead would be less than three feet). I could then remove the long lead between the two solenoids and start the generator
from the windlass battery, keeping it charged with a separate charger?
put acr's between all 3 banks.
Sorry to sound thick, but what are acrís?
Keep the house bank as one bank.
Iím not sure what you mean here. Are you saying to join both port and stbíd banks together?
make sure everything is fused properly. there is no fuses in this diagram.
Where should I install fuses
, and what type and size. There were none when I bought the boat.
you need to watch for the daisy chaining grounds. not the best way to do it. your neg path from the "start" battery to the gen looks super long. like 2x the length of the boat.
The negative from the windlass battery to the engine, through the port side house bank is about 30 feet, all 2/0 cable. By the way, there are no signs of corrosion
on any of the battery terminals.
