Coil problems
It's all about teamwork Seb so here's a tasty smiler from my lunchbox I'll also share 

Thank you kind Sir!
And the mid afternoon snack is................................?
Cheers, SB
Thanks Sprock - got them last night, then tried installing them. I cant seem to get the wires to reach number 4, and number 2 is also giving a fight. When I took the coils off my bike, the convex rounded side was facing up. It seems to me that the wires might reach if they were bolted in with the flat side facing up???? Any hints ?
Thanks much and Merry Christmas!

Alright guys, put in the coils that the Sprockmaster sent to the keys.
If I'm sitting on the bike, the left coil is to my #1 and my #4 cylinder plug wires. Right coil is to my #2 and #3 cylinder plug wires. I put a basic 12v test light onto the wires that plug into the backside of the coils. (left side of the left coil goes to #4, right side goes to #1. The right side of the right coil goes to #2, the left side goes to #3) I'm getting a bright test light reading when I touch the probe to the left side of the left coil, (#4 cylinder), and I get a bright light when I touch the left side of the right coil, (#3 cylinder). When I touch the probe to the right plug connections on the back of both coils, I get a very, barely visible, dim light. There is no change with any of the tests if I hold the probe to the plug connectors while I am turning the starter.

Here is pic of the HT leads on my 1987 Hurricane

My only contribution is that you have them correctly located. Will follow your progress to learn. especially as some of my wires look rather stretched/frayed
good luck with it!

88 that sat for seven years in a garage. I just picked it up, and I was told that it was running fine and parked for reasons of a new baby, etc... I'm thinking I need to call bs on this info that I was given because....
The bike has brand new plugs, (look like they never were fired), fresh gas in the tank, and a few small wiring adjustments that I have come across in the harness, (plug cut and spliced around). I have replaced the coils with a used set, put a new battery in her, drained and replaced all the fluids, and have attempted to get her to fire with starting fluid. After getting nothing, I pulled plugs to look for spark and spark I have none!
Little background, I have never worked on a bike before, (I've built a few small block v8's), but I'm learning as I go with this. The only things I have done to test things in the electrical ignition system are: checked all the fuses including the one next to the battery, put a 12v tester light on the back of the two coils, and checked that my harness plugs were secure and not badly corroded.
When I put the test light on the back of the coils, I get a bright light when I touch the #4 plug on the back, and the #3 plug on the back. (I touched the tester to the plugs on the back of the coils while they were plugged in) When I touch the #2 and #3 plugs on the backs of the coils, I get a barely visible dim light. The only change that occurred when I did this while turning the starter over was that the two contacts that were bright slightly pulsed. The two that tested dim did not change at all while engaging the starter. I have downloaded the service manuals and I am going through those to see if I can narrow down the culprit. From what I have read I'm going to start looking at the ICM and the pulse generator. I have to see if I can find my multimeter and then figure out how to do the proper tests.
I am assuming that I bought a bike that someone else couldn't get running and it seems as though they could not get spark either. Any suggestions or short cuts to narrow this down would be a much appreciated.
Thanks,
