Increase Alternator Amps??
Need a little insight here.
I have never really thought my alternator was putting out its full capabilities (50 Amps) but I have recently added a second battery with an automatic switch/isolator , two amps, and (4) neon strips. In addition I have Perfect Pass as well. Two things are happening when the batteries are low: The PP will reset itself when I turn on the neons (Battery #1), and the radio will kick off when I turn it up too loud with thumping (Battery #2). I also know they are low because I throw them on the charger after trips and they show 60%. So, I plan to get the Alternator rebuilt. The questions I have are: (1) Should I need to increase the amp output with my current set up? (2) If I increase the amps, do I need to update any wiring or breakers? Thanks for your help!

Guys, I am not planning on buying new. I plan to rebuild what I have.
The questions relate to: should I increase the amps, and if I have to change anything else in the boat if I do that. Thanks for the help.

the case on your 50a alt isnt big enough to get any more power out of it.
you need a larger alt, period. I have them custom made, by hand in the USA look in the classifieds

I would upgrade the wire from the alternator to the starter/battery to at least 4ga.

Thanks guys! The company that I was planning to have rebuild it said they could increase the amps a bit as long as they could get a particular part. The actual increase is unknown until I take it in.
