Those who have done a Millenia or ZE alternator swap...

I believe the ZE/Millennia alt is 110 or 120 amp. Fuses are not going to blow unless the load on the circuit that the fuse is protecting exceeds the fuse lmit. That said there can be as much as 200 amps going to any fused circuit but if the load exceeds that fuses limit it will blow. It doesn't matter what available amps were there to begin with. The other consideration of course is true Barry. You can't exceed the amperage rating of the wire concerned either. Having a 200 amp output alt shouldn't affect anything downstrem unless it was faulty in the first place. It in no way means that your sending 200 amps anywhere but allows the availability of more loads without the extra stress.

I swapped in the 110amp alt with my ZE swap and it is definately a 12V signal going to the IG terminal. I had it verified by an auto electrician first just to be sure. I used the 12V ignition signal going to the disty (the orange wire from memory?) just tapped the wire and then trailed it along the loom going to the alternator, looks nice and neat that way. It's been running fine and charging now for about 3 months so i guess its right. The only down side is the headlights no longer dim with the bass....

Go with the 12V...My manual confirms this. And tapping into the disty line....isn't that like free energy!!!! To be safe, I would run a line with a in-line fuse. Go with the suggestion from Pauli_au or run an independant line. Just run it with the wires that lead across your rad support existing and tap the battery. Use a 14awg T-90.

I may tap that line, currently ( I have a millenia manual and found the pinout voltages) I have it connected to the power window circuit and have an inline 10A fuse between the two. Did that last nigh. Cant test it though, my PS pump pully is bent

Definately change that hook up. Every time you use the window, who knows how that can effect your power consumption. Go with the battery...the wiring will be far away from the heat of your block, and you already should have wires leading across your rad support plus inline fuses are cheap but keep them away from heat too...intall just after batt/drivers side....Good luck with the pully issues....been there, done that!
