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 C |

Jim you are a big help.. I've obviously been typing as you were submitting. The wording from MSD's instructions had me confused about the white wire. I'll make that change. Also, come to think of it I don't even mave a ground strap for the tranny. I'll stop at FLAPS tonight and pick one up. Any particular place to install it?
two more questions: 1) What terminals connect the alt light to the wiring harness (in and out)? I have a mysterious red wire that comes out of the wiring harness but isn't installed into the plug itself..I'm thinking this is the reason my alt light isn't coming on. 2) (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) ....I forget the second question.
