Question about 1999 Yamaha YZF-R1
Hi, Tom in order to check out any main electrical system, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary. "WARNING" never plug or unplug any electrical connector with the engine running !!!
1. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is "GROUNDED" and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the multimeter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the multimeter should read infinity. Connect both leads to the alternator multimeter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.

Needles stuck indicative of instrument cluster complete failure. Cause unknown. This is second instrument cluster that has failed on this bike, first one failed at about 3000 miles, twenty-two months ago. This "new" one died in mid May 2008. Received word from Ducati North America that they will accept the warranty claim for the toasted instrument cluster!!! Am still concerned about cause...this is second instrument cluster for this S2R800. Seems to be an issue prevalent on some of these late model Monsters. Will update more after instrument cluster gets in and replaced by Bloodworth Ducati in Nashville.

Hi and welcome to FixYa,
Initially, determine if there is a clicking sound when the START button is pressed. The click is significant. If there is, this indicates that the starting relay is engaging but for some reason, the starter motor is not cranking. This could either indicate a faulty starter relay (particularly the contacts) or a faulty starter motor (specifically, the carbon brushes). To determine which:
Good luck and thank you for using FixYa.

SOURCE: R1 start problem
I had the same problem. After throwing all kinds of money at it, like a new battery, new relay, checking the fuses and many other things. I finally took it to a great shop (M Racing in Glendora, CA) and they discovered it was the starter brushes. Now Yamaha sells a rebuild kit for the 06 R1 starters but it's on back order all the way to Japan. Turns out Yamaha Japan knows about this defect and word is it's going to take months before they start producing the rebuild kit again. I'm sure there will not be a "starter recall" as that would cost Yamaha way to much money which is what the worlds all about, right? Anyway, my starter was rebuilt by a mechanic that rebuilds starters and I haven't had no problems with it. Hope this helps and whatever you do, don't take your bike to Montclair Yamaha. Dealerships charge way to much money and don't get the service or quility of work we all deserve.

Mate, what you are describing an Engine trouble warning light. If any of those circuits are defective, the engine trouble warning light will come on, and then the multi-function display will indicate a two-digit error code (e.g., 11, 12, 13). If the multi-function display indicates such an error code, note the code number, and then have a Yamaha dealer check the motorcycle. As all those require a specialized testing tool I would recommend you to take it to a dealer unless you know what you're looking for. Good luck and don't 4get to rate the advise. Cheers
This warning light comes on or flashes when an electrical circuit monitoring the engine is defective. When this occurs, have a Yamaha dealer check the self-diagnosis system.
What it does is to tell you something is wrong in your various electrical circuits.
