Alternator for my 470

[hanahawaiian]

I got Great Killer Deal for 100$ Alternator KIT from Ebay.. it was WAGNER Products Alternator KIT for 470..

It pretty good deal and look good..

But here my QUESTION is... Im not sure debate between 65 AMP or 100 AMP or 105 AMP from Marine approve Delco Alternator 1 wire..

Im plan to have Subwoofer and sound system on my Boat.. so Im think plan to add 2 battery for in case?

Thanks..

I don't think you really need more than 65A.


The second battery would be a good idea though....that way you use it to run the stereo and amp, while the other battery is always available to start the engine.


Cheers,


Rick

good points.. I have 2 battery both are brand new.. and I was think do Switch knob for 2 battery switchs.. so im think use 65amp alternator to use on Both battery to keep both battery charged good..

Re: Alternator for my 470

There are battery isolators out there that would allow you to charge both batteries without drawing current from both batteries...

Here's some examples...

And here some info on isolators too!
