Ok just finished installing the 96amp Saturn alternator. Not as simple as the writeup makes it seem but I'll get to that. <b>I now have no spark!</b> Fuses ok. I replaced the main brown cable to the battery from the alt, and repaired a couple damaged wires but none of them have anything to do with spark (oil sensor, temp sensor, anti-run-on valve). I only spent a few minutes trying to figure it out so hopefully someone has a little insight that will point me in the right direction.
The original wires are supposed to be large brown, small brown, and small brown/yellow. The main brown cable was actually a black one with a 4" piece of brown soldered on the end then just taped into the loom.[V] Amazing that a new car could leave the factory that way but I guess that's how you get on the 50 worst cars list. The other 2 wires are a solid <i>yellow</i> one and a brown/yellow. I just assumed that the solid yellow was supposed to be the brown one. Even if these are wired wrong they don't have anything to do with engine spark, do they?
One question to anyone who has done this upgrade; the writeup clearly states to cut the black wire (i left it) but the schematic shows the outside wire cut (which in this case is brown). So which is it?
As far as not being as straightfoward as Greg Bober's writeup that comes down to the bracket (and the wire color issue). The backside needed to be cut so it wouldn't hit the alt. And the front needed to be ground down a bit so the alt fan wouldn't hit it.
Had to cut on the angled line..............Notched out for fan.
