I know this an evo, and worse a softail. But I also know you fuckers have some serious knowledge, so I'm hoping that the mods will let it pass. So I gutted the wiring harness on this 99 softail I picked up, and tried to re-wire using a simple diagram I got from Rudehog on here. He was actually tons oh help, trying to somewhat style the bike after his old one, only cuz it's probably the most tastefully done softail I've seen (outside of Danny F.) but I digress...

Here is the diagram I used:

wiring diagram.jpg

I added some shitty drawing using paint on my computer trying to show where mine is different. I'm trying to use the stock ignition module, and my coil only has two pegs (dual fire?) not three.

And here are some more pics just for reference.

wiring is fcked 001 (640x480).jpg

wiring is fcked 002 (640x480).jpg

wiring is fcked 003 (480x640).jpg

wiring is fcked 004 (600x800).jpg

new look 023 (480x640).jpg

So the lights work, the starter cranks, but I got no spark. I got fuel. I soldered and shrink wrapped the connections form the cam sensor to the stock ignition module, and used my manual to get it right from my ignition to coil. I have a wire running from the ignition swith to coil. My multimeter shows power to the coil, but I got nothing.

I'm about ready to scrap it all and start over with new components, ignition coil whatever. Everything worked fine before I took it apart, and I'm inclined to think it's my wiring...but this is frustrating.

Am I missing something with the lack of kill switch/additional ground from coil or something? If the module is fried, will it not spark at all? I'd appreciate any help, even if it comes with "your an idiot" attached.

Is there a white wire from the module to the coil? It should go to the 12V side.

Yeah, it's white, I just couldnt color it that way in my shitty drawing. I did however momentarily have the wires to the coil reversed...could that have fried either the coil or the module?

Yeah it may have wiped the module if the blue wire saw 12 volts. I have a 7 pin Screamin' Eagle somewhere if yer stuck. I may have a stocker somewhere. Have to look around.

This is my first harley, got it for real cheap...previous bike was a 72 triumph, so the wiring was a far cry different to say the least. Geezer, I don't know what a 7 pin Screamin Eagle is...but would a fried module be a possible reason I'm getting no spark? I may be interested in the stocker if you have one...

would my coil be junked now too? can I test it with my multimeter?

also, does everything else look ok as far as how it is wired? I don't want to keep fcking up parts...since I only have two pegs on my coil, would the wire to my ignition go to the "hot" side? there are no positive/negative markings on the coil, just did it on how it was wired up with the harness...the wires to the coil were pink and white.

If you followed the diagram posted it appears fine to me. The 7 pin Screamin' Eagle is Harleys high performance line module. 7 pin refers to the number of wires on the plug-in connector.The coil is polarity neutral so it should be fine.

Here's a check for ya.

First of all be sure all grounds are clean and tight.

Remove the timing cover over the sensor. Turn the engine over manually (get the rear wheel in the air,put it in top gear and use the rear wheel to turn it over if no kicker) and make sure the open area of the cup is NOT in the sensor gap. Before removing the timing plate mark the timing plate with a magic marker so resetting timing is easy. With the test meter set on DC volts probe the module connector to the sensor from the back of the connector at the red and black wires w/ignition and kill switch on. Should read about 5 volts. If not it's toast.

If it passes lemme know and we'll look in a couple other areas. But sounds like it's done.

This is the timing sensor I refer to.

thanks geezer, I'll try this tonight and report back. appreciate the help.

wait though, I don't have a kill switch...should I have accounted for that somehwere since I'm using stock ignition module? I've got basics only on it, like the diagram above, except I kept the voes...

if you reversed the 2 wires to the coil or ign. And sent power to it
you smoked the units.

You should run a kill switch but it won't have an effect on the workings if ya don't.

ok, so my module was toast. thanks for the test geezer. so I went ahead and got one of those package deals, new ignition fits in the nosecone, came with new rotor and a singel fire coil, now it matches up pretty exactly with the diagram. I got spark, but still haven't got it started. I thought I had it statically timed per the instructions, but I may have to revisit it. I got the battery out and on a trickle charger, since it had lost a little voltage (hasnt been ridden in almost a month, and all the turning on the battery constantly to check everything).

I'm going to go over all the wiring one more time, make sure I'm getting fuel, and try to get the timing right once again...
