- August 05, 2014, 18:19:46 PMOk... So this morning I turn the ol' key switch... Hit the starter... One one thousand... Two one thousand... Vroooom, Blap, Blap, Blap... Fires right up... Gotta be shortin' something from the dampness... @ Troll... Mine would be sealed.

WD40 = Water Displacement formula #40.

- August 04, 2014, 21:51:41 PMHere's an old mechanic's trick from an old mechanic. Don't spray water on the electronics. Spray WD40 on it. One of the characteristics of WD40 is that it displaces moisture. The other is that it is nonconductive. The next time the bike balks due to dampness, start spraying parts of your electrical beginning with your plug wires. Then work your way around until the bike starts up. Chances are the last thing you sprayed is the culprit.

- August 04, 2014, 20:30:31 PMGood question Troll, I'll have to check... What's the difference... What do I look for... Can you tell by the pic... I do know that if I turn the switch left my tail lights come on... It just has term posts protruding... 3 top (11:00, 12:00 and 1:00) 3 bottom (7:00, 6:00 and 5:00)

Is it one of the sealed switches, or is it the brass roller and pins type?

The OE switch has the resistor built into it... I matched it up at RadioShack and soldered it in (shrink tubed, Lawson's electrical tape, damn near bullet proof) maybe it's one of the term connectors at the switch?
Hell, H-D switches don't work on H-Ds half the time...I'll bet I've replaced those switches on every H-D I ever had at least twice....The thunder kit uses the H-D switch, so I'll bet you still have an issue like I had. Check all the connections and re-solder the resistor.

- August 04, 2014, 19:07:23 PMAre you sure the battery is good. There may be enough power to run the ignition system, or turn the starter, but not both at the same time - which would explain why you can bump start it but not start it with the starter. A sure sign that your battery is shot is if the clock resets when you start the bike using the starter (because of the voltage drop when the starter kicks in).

- August 04, 2014, 18:25:29 PMIs this one of those thunder ignition kits? I use mine to control my stereo amp, now....The ONE time I had to walk home was when that ign. switch refused to turn on the fuel pump...

- August 04, 2014, 18:20:32 PMThis one is odd to me... Whenever it's damp or misty out old "Evelyn" will just crank and not start, Yet she'll start if I bump her... I'm getting fuel, The battery is fine, Plugs are good... Only happens when it's moist. I'm wondering if this has anything to do with the key switch resistor (Inline with the ignition switch that cuts all other power to send enough juice to the starter) Does this make sense to anyone else? I'm thinking maybe I'm getting moisture in the wiring (I did relocate the switch to the speedo cluster, But that's been awhile... This problem just started within the last few months) Someone suggested starting the bike and spraying water around the ignition wiring to see if the bike shuts off... Any suggestions? Thanks in advance, Bake
