Rain Killed my Vulcan

Hi guys,

I've posted a couple times here on the forums. I have a question. My bike sat outside in some mild rain last night for about 30 to 45 minutes. When i went to start it up the next afternoon (today) it would not start. It cranks the starter and I can tell it's getting fuel by the way it wants to fire. It just won't run for more than 2 seconds.

My best guess is the problem is electrical. I do know it is driving me absolutely bonkers because it is my only transportation and it hates rain.

The previous owner is a friend, he replaced the fuse box with a brand new one the one time this happened to him. The bike refused to run for him even after the water dried up a week later. He replaced that black box and it ran again.

Ideas? I am almost certain once the water/moisture dries the bike will run fine once again. But it should not be doing this.

There are sprays for drying electrical stuff on cars like for distributor caps and plug wires. You may want to try that on the kill switch and ignition connections. Have you done the coil mod on your bike? Once it's dried and running you might want to go through all of your electrical connectors and grease them liberally with dielectric grease.

Living in western Washington state, I'd be in serious do-do if my bike did this when it rains. It unfortunately sees a lot of duty in inclement weather.
Coil mod???

Wired George has a coil mod that puts full battery power to the coils. His however uses a relay which is needed for point systems but all the vulcans have electronic ignition right? So the coil mod for these is quite simple. Disconnect the coils at the wiring harness. Run a wire with inline fuse(10a) directly to the positive battery cable at the solenoid to the wires to the coils and you're done. Just cover the wire at the harness with tape. I did the relay version on my old KZ750 twin. It starts easier and pulls harder now. Best bang for your buck going in the way of mods for older bikes.

I have never been in the rain with this bike. Getting caugh in the rain and the bike dying on me is one of my concerns. One of this warmer days i am going to start the engine and spray water on it while it idles. It is not a total simulation but it is close to it.

I just bought a fresh tube of dielectric grease. I will be going through all the connectors and cleaning and tightening the connections then they'll get greased to keep out moisture and slow the possibility of corrosion. I suggest you do the same before your bike gets wet.

I hope rain isnt a problem. I ride long distance and it could easily rain. It would be a disaster to be a few hundred miles out and be stopped by a little water.

Rain isn't the problem. Most likely, it's an already corroded or dirty connection made worse by moisture. Take the seat off and check all the ground connections and ignition connections. The electrical systems on our bikes don't take much to prevent them from starting or running smoothly. Once all the connections are clean, try it again.

I've ridden in some very torrential rain and as long as I keep the electrical system clean and tight, I haven't had a problem. Like any other piece of precision equipment, if you don't take care of it, it won't take care of you. If you ride in the rain or let the bike sit out in it, you'll have to check the electrical connections more often. If you don't have any kind of covered parking for it, I'd get a bike cover to protect it from the rain at night or while at work. You can get a generic one and they only take a couple of minutes to put on.
