HO alternator/Dual Battery/Battery Separator/"Big 3 Upgrade

Well there you go I guess it can't hurt but do you "need" it, who's to say...but the big difference in what @Digiratus said is a Circuit Breaker not an in-line fuse

 

Circuit breaker is ok but a slow-blow mega-fuse is a better match to what oem uses (fuse-able links).

A fused alt wire however you do it via circuit breaker, slow-blow mega-fuse or fuse-able link are there for a purpose. If your alt goes haywire and starts putting out more amps than it should it could really heat up your wire. If your wire gets hot enough it could burn through its own insulation and possibly start a fire. Having a fuse of any of the three sorts above will prevent that.

 

I was going to put in a 250 amp ANL fuse for a 200 amp alt. What would classify it as a "slow-blow"?

 

It is advertised on the fuse makers description. Here is what is found via Oreilly's Auto Parts web page:

I'm interested in your battery tray. I am trying to fab one up, or modify an existing one.. no welder on hand. I was thinking of starting with an existing tray (or similar), and figuring out how to mount it on the fender and make it work. I like what I can see of your setup. Any more info or details? Thanks.

 

My tray is factory/stock, but your linked tray should work. It seems to have raised ridges so when you bolt it down the heads of the bolts wont rub on the bottom of the battery. Should be pretty straightforward and no welding necessary. Just watch the tops of those j-bolts so they don't hit the bottom of your hood. Good luck.

 

Sorry I should have specified, @chazjb s the tray for the passenger side battery

 

Oh for a side mount like that, I wouldn't trust that particular tray. I would personally look into more of a box type tray.
