my answer. on most bikes its under a side cover
older can be behind head light.
or under seat.
when you clean a bike 100% all that gets seen.
on most bikes, lift seat see, operators guide, and bingo on fuses.
all bikes made,
my bike is 1966 and has a tool box. in frame center, and guide is there.
on other bike, lift seat and there is underseat hidden spot , pocket.
and bam.
its in a place that water might not hit. (they all do)

Usually if you flood it (by overchoking), you open the throttle wide open (to draw in more air to lean the mixture) while cranking starter.
Beings you had the spark plugs out you could have cranked it then, and let the engine compression blow the excess gas out the spark plug holes.

it is not a fuse, it is a circuit breaker in the fuse box, which i believe is under the hood on that car, i would check for bare or shorted wires behind the stereo before doing anything with the power seat.

Either under the seat or behind the triangular plate on the left side of the bike.

I'm telling ya, since harley went to all this computerized stuff on the bikes, they're getting just like our cars got. It's getting to where you can 't work on them yourself anymore.

The ignition circuit has it's own fuse now. Since Harley went to fuses instead of circuit breakers, the slightest thing and you're down for the count. With circuit breakers, you could short something and a few seconds later, you were ready to go again. These days, you've got to find the fuses and check all of them. I don't know where your fuse box is located on the bike. The header says you have a 2000 Road King. If that's right, I think the fuse box is under the seat or the right side frame panel. That's what I'd check first.

Of course, you know that you've got a compression sensor on your engine. If you take the plugs out of the heads and put them in the wires, you won't get a spark. Take the wires off the spark plugs but leave the plugs in the heads. Put another set of plugs in the wires to check for spark.

If you'll contact me directly. I'll scan a troubleshooting chart and send it to you. It may or may not help. Seems Harley changes stuff as often as the Japs do now. Contact me directly at my personal e-mail wd4ity at bellsouth.net Remind me of what you need, ignition system troubleshooting chart.

Good Luck

can i assume that you mean the bike cranks over but wont start? Well you can rule out immediately changing the oil...(unless you used way too thick an oil brand, eg: a 20w50 or heavier and live in a cold climate), but i"ll assume you dont and you live near the beach where it nice and warm. Now you changed all four plugs, when you pulled up on the plug wires, i"ll assume that you didnt pull them up by the small diameter wire and pulled them up by the boots instead while twisting them out correct?, because this is the correct way to pull plug wires. The other way damages them, also you made sure that you heard a clicking noise letting you know that the plugs were firmly seated to the boot..o.k. And im almost positive that you went out and purchased the "same" exact plugs that where in there. Now take the #1 plug out and let it touch the frame of the bike, start the bike and look to see if you get a big blusish spark, not a reddish-purple. if its reddish purple you got either a bad coil or the pulse generators are going bad. Now i"ll assume that you didnt replace the plug wires and hopefully didnt get them out of firing order and replaced them one at a time to insure that they would be in the correct position? the bikes left side coil = #1 and #4 cylinders, and the right coil= #2 and#3, so now...this just leaves one more thing, did you check the gap on the new pulgs before installing because even though they say they're pregapped they could be wrong, just the other day i changed the plugs in my car and the where all off by .003. Anyway if you did everything properly did you possibly trip the kill switch, or dump the bike tripping the titlt sensor? because this will kill voltage to the fuel pump and it wont start. Check fuse to fuel pump, if good, then disconnnect battery for 5 minutes, and hook back up...now measure voltage on the battery since you have the seat off ...the battery should read at least 12.5v or > or it probably wont start. Next take the connector off the fuel pump and check it for 12 volts as well. The bike should start now.
Now if you mean the bike wont crank now thats a totally didnt story. and either your solenoid went bad... but you can find out real quick by taking a srew driver and following the two battery cables, it"ll lead you to a small black looking thing with to big terminals on it,..just turn key on and short together these to post with the screw driver, if the bike starts, then its a bad solenoid, or if it doesnt the starter is probably at faulf or the wiring going to the starter.
hopfully this will help you get it going good luck
Can i get a very helpful rating Thanks!
Now if all this fails theres one more thing to try (after you have insured yourself that everything was done properly), and that is to try and see if it will push start!...if it does, then its a fuel issue, this means that you have an fuel injection problem and maybe something is clogged up so go to Autozone and purchase a can of Sea Foam and pour 1/3 can into 2 gallons of fuel and ride the bike after the push start and ride it for 10-15 miles to see if this will clear it up. it worked for me after 11 miles.
Can i get a veryhelpful out of this one...thanks!

the next thing is the cdi unit buddy 1 st check you have power coming out off magneto use volt metre get back to me

most yamaha bikes have fuse box mounted behind left hand sidecover beside sarter relay or under the seat behind the battery

Yea I have a 06 c50 boulevard. Pull your seat off and below it will be the battery and a few fuses. I can't remember for sure 2 or 3 fuses, check to see if there blown. When I had that problem it was a blown fuse. Cheap fix if you know where the fuses are.

check under the seat they along with the battery hide under there make sure the battery is charged and check for blown fuses let me know if this helps
