I have the same setup that jbc426 has except I went this route.

It doesn't quite have the power that the CS-144 has but it is close and easier to wire.

Idle amps are about 80 with total output around 140amps

My came with testing specs. (they must test each one after building it) that show the actual output was 154Amps with 95 amps at idle.

High amp at idle and stock look (late 70's). I tried the 140 amp GM case Powermaster first. No fit with a BB and aluminum heads. I ran a 75 amp square back for a while but it just barely kept up when running and gave a big discharge at idle. I switched to this from my 78 Cordoba core engine and it works great. Just heavy.

cjskotni...I'm trying to set up for worst case scenario if the fans were needed to be at wide open. If I go with this fan idea, I do plan on running the controller Howzywhatsit (sp) has built for it. I haven't checked with him to see if he has a selector type controller for more of a manual/driver's control of the percentage of output (another topic). Good battery is understood.

jbc426... I'm planing on better than stock head lights on relays, but I haven't got to that bridge yet, the rest of the car will be on LEDs. The CS 144 may be what I have to do. A lot of things I've chose to do have pushed me out of the stock look, but I keep trying.

I have read some on the one wire bypass & the 2 wire with the ammeter & bulkhead connecter deal. I ran into that the hard way back in 85-6. I'll try an run extras on relays.
Mad Electric...I've see the name but haven't read there yet,...will have to do that.
