Changed Spark Plugs; Bike Will Not Turn "ON"

I just changed my spark plugs using the Haynes manual and instructions from bolty.net. Pretty straight forward and I followed the instructions exactly.

After I finished re-plugging the boots I turned the key to the "ON" position and lights and odometer all come on like normal. Flipped the switch for the starter to On (fuel pump turns on like normal) and then press the starter switch. Immediately after pressing the starter switch everything shuts off and the bike is dead. I turned starter switch off and turned ignition back to OFF and then ON; nothing comes on now.

I checked the main fuse, ignition fuse and fuel pump fuse and they all look intact. When I turn the ignition to ON, starter switch on (no fuel pump turning on this time) and hold the ignition button I hear what can best be described as the sound of an old creaky door opening slowly coming from the starter relay / battery area - I really hope that makes sense.

Any and all help is appreciated.

Thank you,

Brad

Make sure plugs are inserted fully and correctly as well as gapped correctly. Make sure no wiring came undone. Wouldn't happened to have got any moisture in there?

If it worked and turned on right before that.. then it has to be something with the installation of the plugs. Maybe go through the process again?

EDIT**: Just re-read and noticed you said the fuel pump isn't even priming. Not too sure. Start with the battery I guess.

I think what you have here is what's commonly called a "coincidence" or in some circles a "coinkidink". Changing plugs should have absolutely nothing to do with the problems you're having. You could take the plugs out completely and it should still turn on and prime. How old is the battery? Get thee a charger and let it do it's thing. My money is on a loose connection or dead battery, or both.

your battery is toast and needs to be replaced.

12v static battery just means it's charged. putting a load on it is what matters. if it drops below 8 it will probbably not come back to life. yours drops to 1v so it's definitely shot, charging it will not do a darn thing.

batteries go out. mine failed about a month ago. rode it to work that morning, it started fine and everything. worked all day, went to leave, turned key on, lights came on, hit the starter and it popped [sounded like a fuse]. checked them and they all were good. then load tested it and it didn't even have enough power to turn on the tester display.

it sucks!

Mine popped too, so that makes me feel better. Definitely sounds like it's the battery then; how strange for it to just die all of a sudden.

I'll be sure to follow-up when I get the new battery in.

I'll be honest, I don't really contribute to this site, but I am very grateful to all of you out there who take time to answer mine and everyone's questions.:)

There are plenty of battery options that are "factory activated" w/o having to spend for a lithium battery. In Yuasa models, instead of the YT12A-BS, you can look at the YTZ10S or YTZ12S. I think when I changed out my battery I used a YTZ10, or something similar to it, as I was looking for something a little shorter. As long as you get something that physically fits, has terminals that you can connect to, and has enough power (in most cases doesn't even have to be quite as much as the original), there are a lot of options. You can refer to the Yuasa specs, but there are plenty of other brands that make comparable models, factory activated, or otherwise.
