I wasnt really jankin though...i was inspecting.

The ONLY component that was in it when the starter shorted thats still in it is the battery.

But i would think if it was the issue it wouldnt start or atleast slow crank or die when sitting.

Heres a diagram of the charging system...

It seems pretty simple and ive been through all of it...except for the wire going from the regulator into the cluster...not sure of a good way to check that

So i had the alternator tested last night....

Either ive gotten 2 junk ones in a row from napa or something on the car is killing them. I got on car-part.com theres a junkyard about 30mi away thats got a tested good OEM one for 50 bucks. NAPA said if this ones garbage theyll refund me.

Looking at that diagram im not sure what could be killing them if thats the case. Unless its the battery...which also tested good but i figured it would. Im going to install the battery from the B2 and see what comes of that.

Im going to go buy that junkyard one and throw on and see if it gets fried in short order, if it does ill know somethings going on deeper....if it dont then ill just run it untill it dies a slow death. It takes 10mins to change the alternator on this thing.
