I have a used guest charger with a blue, brown and yellow/green wire. Which is the + and which is the - and which is the ground? I want to see if the charger works but the 110 male plug is cut off.
Thanks for your help.

Re: need help with wires on guest charger
Blue is neutral (wide blade on a NEMA 5-15 plug, the standard North American 15A 120V plug), brown is hot (narrow blade), and green or green with yellow stripes is the equipment grounding conductor. That's an EU convention, per the HD 324 S2 standard (IEC 60445), I believe.

Thanks Tom..
The charger is no good. No lights came on when I hooked it up to a plug. Any ideas on a good charger. Plan on having 2 105s for house batteries and one starting battery or maybe I just need 4 105s and use 1 of the sets to start 50hp motor.

Re: need help with wires on guest charger
Is it hooked to a battery? And is the inline fuse good?
As to chargers, there's a huge assortment out there. I use a 5/5 12V charger by Guest, which is now labelled Marinco. Two 12V outputs at 5A each. I only have two flooded 12V batteries, though.

My last boat had a 3-channel charger with higher capacity per channel (10A each maybe?), but those are a lot of money. Xantrex, I believe.
Many folks just use one charging circuit and charge relays to charge downstream batteries at the same time. You've got a LOT of battery capacity, so I would think, for shore power charging, you'd want pretty high capacity. Using a charge relay will also allow the engine to charge all the batteries without using the ubiquitous 1/2/1+2/off battery selector switch.

Re: need help with wires on guest charger
What are you powering? 4 x 105 amp hours will run a fridge and everything else on a Mac for the better part of a week.
I still run my mac on a single battery and I carry a jump-starter. I have a cheap (<$100 waterproof) charger for charging from shore power.
The one battery has done everything I need including heavy trons and autopilot use. I don't have a fridge, we use an ice-chest instead.
Carrying around 200 lbs. of battery weight everywhere I go doesn't interest me.
