Thumbs up green neutral light

Hey all, I just picked up an '03'919 with a rebuilt title,with 2800 miles for $2500! I love the low end power and handling. The neutral light does'nt come on? I have an service manual comming. Any thoughts on what to look at first? Also after a ride,I notice a several drips of coolant on the floor out the drain hose. Is this normal?
I think this bike rocks (way better than my YZF600)! I kind of wish I had a new one, but the price was good and the frame and motor seem fine.
I just got new m3 tires and a stand. I bid on EBAY last nite for a green tank and rear cowl but did'nt get it. Thanks for any help, Ilovheros

Hate to state the obvious, but might the light be burned out? Not sure if there is a way to check it without taking the cluster apart. There is a wiring diagram here.
As for the coolant, unless it is overfilled from what I understand, no there should not be any coolant dripping after a ride.

Yes. It will drip a little when you turn it off until it the level down to a point that is lower than the overflow tube when it is fully hot and turned off. (If this makes sense.?) Basically, it needs to be at a lower lever to stop dripping. It can take months and months at 2 or 3 drops per use cycle. If it's a nuisance then take some coolant out of the overflow bottle. Otherwise, ignore it. Let mine drip until it stopped on it's own.. took also two seasons.

I had the same thing here. Mine is an 05'. Just keep an eye on your coolant. Once it stops dripping and your coolant level is fine you are good to go. Should be nothing to worry about.

Electrics!

+1 on the level in the reserve tank -- mine needs to be about 6mm below the upper level line to not drip.
As for the neutral light, it's an LED, so is very unlikely to be burned out. Does the starter work in neutral without pulling in the clutch? If so, the neutral switch and the wiring to the clutch diode in the fuse box is good, and the defect is further up in the system, starting with the neutral light side of the clutch diode. From there it is hard wired (no intervening connectors) to the Light Green/Red wire in the black 9 pin block connector inside the headlight shell. To test the light, turn on the ignition switch and ground the Lg/R wire on the main harness side of the connector -- the light should come on. If it does, the problem is either in the clutch diode or the wire to the black connector is broken somewhere inside the harness -- look for any chafed or cut spots on the harness wrapping as they may indicate where the problem lies. If the light does not come on, it may be burned out, the pin in the black conn. may be pushed back, one of the mini connectors to the gauge board may be partially unplugged, the wire from the black conn. may be broken, or there is a broken trace on the circuit board. There are quite a few possibilities, but they can be eliminated one at a time by a visual inspection and signal tracing with an inexpensive digital volt meter from Radio Shack or Harbor Freight. If you have gotten this far and get stuck, post your inspection results in as much detail as possible, and I'll try to go into more detail.
If you need a wiring diagram, there is a good one posted in the Helpful Topics for new 919 owners: sticky at the top of the 919 section, third up from the bottom of the Helpful How To's section. Just zoom in and trace the circuit, starting at the neutral switch. Good luck with this.
For everyone: while I was looking at the neutral light circuit, I figured out the sidestand kill function. The ECU monitors the sidestand switch (G/W, ECU pin 21, Gray conn.) and the starter signal wire (G/R, ECU pin 10 Gray conn., indirectly sensing the neutral switch). If it does not see a ground from the sidestand switch (stand up), it will cut the ignition unless it sees a ground from the neutral switch.
