Here's the deal...I have an '01 SAN and have upgraded the stereo to 3 amps totaling 1800 watts RMS. It does not have a heater, shower, or tower lights. I have 3 blue tops, 1 starting and two stereo batts. The stock alt is ~50 amps and can't keep up. I was about to have the stock alt. rewound for ~$250 at Autolectrics in San Jose. He said they could make it a 125 amp alt...then I ran across a Delco 100amp HO alt at a local boat shop for $194 brand new. My questions are:
1) How big an alternator do I need?
2) How big of a circuit breaker do I need to install?
3) And on a side note...How big should my inline fuse be between the batteries and the distribution block? ( I figured 1800 watts/12=150 amp fuse...sound right?)
Sorry for all the questions and thanks for any info!
