Dyna S install question

[chef1366]

Three wires guys
Red to O/W and the other two to the coils.
Make sure the kill switch is on.
The neutral wire will only be hot when the bike is in neutral.

Classic point for large voltage drops on the GS is the Ignition switch..... you are having a problem only when connect to a SWITCHED LIVE right?

Make sure it's nothing with "lite" in it's name

I think this is the answer. A lot of fairly modern electronics will not work if they don't a good solid 12vdc. Check and clean the usual connections as well as those pesky contacts in the bottom of the ignition switch. The lazy mans way, especially on an "S" would be to install a switched relay for the ignition just like I did.

This has been a terrific help! Thanks a lot guys, I'm sure that the info from here will help us to get the ole girl fired up very soon.

And as Rob said, 'lite' isn't in our beer vocabulary, we'll be having some 6.5% IPA with an ibu rating of about 80!

If I may humbly point out, that with 6.5% it's not surprising that your having problems.

What is your complete test setup/hook-up, whats connected to where and what's not connected?

Your splice and direct differentiation are confusing and in practice there should be no difference. It doesn't matter if you splice into 12v or plug directly into 12v, 12 is 12 no matter how you cut it. The problem with the neutral wire is unplugged one end will have power coming from the bulb and the other end will go to ground when in neutral.

Personally, I think your testing wrong or hooking-up wrong.

Naturally I would think the same thing, that I'm hooking something up wrong, or testing it wrong, but as others have said..it's only 3 wires. White wire goes to coil 1-4, black wire goes to coil 2-3. Red wire goes to a switched 12V, at first the orange/white wire up at the coils, then the rear brake light, finally the neutral switch. It doesn't make any sense to me either that static timing would work when it's hooked directly instead of spliced, like you say 12V is 12V spliced or direct, it shouldn't matter, but that's what is showing up. Very odd. We won't have time to get back at it until next week but when we do and we resolve this situation we will post our findings. Thanks for all the help everyone.

Well we went at it again today..Success!! she fired right up and is running better than ever. We cleaned the wiring harness and installed a relay for the coils. We didn't measure the voltage drop at the coils before we put in the relay but I'm sure that was the problem as you all suggested. It was a good thing we did the harness clean up, we found a main harness 4 prong connector that was almost welded together, and a couple of other 'nasty' connections. As well we replaced an almost melted starter relay, it's crazy what rusty connections can do. So.....nice shiny new Dyna ignition and Dyna coils thanks to 'gearhead13' and a cleaned up wiring harness, MAJOR up grades and improvements done today that's for sure. Glenn is pumped at how fast she starts up now. Thanks again for everyone's help.
