Because my electrical skills and abilities are on par with my nuclear submarine power plant overhaul skills I thought I'd post a request for some help. I figure it's better to ask before I fry something up or electrocute some important part. In addition, I haven't received any calls from the Navy for work. I have a rebuilt AL16X alternator (75amp) to replace the original one in my 86 Spider. The top picture is the original and the bottom is the new one. The back of each are close, just a couple of differences. On the original, the heavy gauge wire attached to the B+ lug and the thin gauge green wire attached to the D+ spade. The regulator is located in the same position on each. The big difference is on the original there is an additional black Bosch part with a wire attached to a spade with + mark. Not sure what it is and that's where I need the help. Does anyone know what it is and do I need to remove it from the old alternator and place it on the new one? The other difference is the D+ spade on the new one is located inside a small rectangular well; I figure this has more to do with the difference in the backs and not the connection itself. The other difference is the old one lacked a W spade (10 o'clock position on the new one). If this is a positive lead should it be covered if it is not used? Lastly, any tricks to removing the pulley & fan off the old alternator? Appreciate any help the electrical experts on the board can provide. Steve
