Help, Alternator Hook up for the /6, I thought I had it right! - ZAP, ZAP.. Options

[DougC]

I have a problem where I get a major spark when attaching the battery cables to the battery. Clay Perrine pointed out to me that it's the heavy RED wire that's attached to the Starter (same place as the battery cable) and runs up to the back of the alternator. Clay suggested that this red wire was hooked to the wrong post on the altenator. OK, I removed the complete CIS injection unit and peeled back the engine shoud. The wires were hooked up to the alternator like in Wayne Dempsy's book, the pictures I took upon disassembly were lost so I had to use the book for this. I'm using a newly rebuilt Marchall alt. with external regulator. Here's a breakdown of how I have it wired:

(posts are clockwise from the top)
"+G1" or "+61" = blue wire
"B+" = Red wires [one thick, one thinner]
"another B+" = short ground strap from engine case
"DF" = black wire with spade end
"D-" = 3 small brown wires
"D." = un-used

Where have I gone wrong?

I just looked at Dempsey's book, page 26. Totally different than my Bosch. It does look like both red's are connected to B+, nothing to D- (?) and green, black and brown (ground?) to other terminals. I think I am out of my league here.
Any chance that the alternator has an internal regulator? I think the change occurred around 1980 but not sure.
I don't think a standard 914 relay board/voltage regulator would be directly compatible with the wiring scheme shown in the pic. I will page Cap'n Crusty, sixnotfour, ArtechnikA on this. I suspect one of them has the answer.
