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?

Doug, are you running your wires to the factory 914-4 relay board? If you are, be careful! They are backwards of what you would think when you hook them up. Dan, can you explain what you mean here? I am using a stock relay board (914/4).. Doug C

On a 914-4 relay board your volt reg plugs into three prongs like this:


| A
........| B
| C

I won't say that A=DF or B=D- ect because I cannot remember that, BUT when you look at the little plug that plugs in just a couple of inches away (The other 3 blade terminal on the relay board), it is this:

| C
.......|B
| A

The terms are flipped on the back blades.
