Question about 2006 Yamaha MT-03
Hi, Jagojohn before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the 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.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter have failed or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. The electric starter is working but starter clutch has failed.
14. Check for engine trouble codes.

buy a new battery shelf life is not 2 yrs the only other thing that would have saved this battery is a trickle charger or battery maintainer

You have a loose connection to the ignition system . When cranking make sure it is in neutral. and kill switch is in run position. The only thing dropping would sensibly affect is the fuel system or jarring a switch., but with the suspension you have there really is no jarring. So, I would ck the wiring. something is loose.

Hey there. I have had EXACTLY the same problem on my 2008 MT-03. It just died on my 2 months ago, when I wanted to ride back home from work. Symptoms: it felt like the battery was dead. I checked it, it was not. Since it was still under warranty, the Yamaha dealer picked it up, picked it apart in the shop and came with the explanation that the central grounding point of the electrical circuit was corroded and therefore, no electricity could flow, explaining lack of ignition. They 'fixed' it free of charge. Yesterday, WHILE DRIVING on the motorway in Belgium, 120 kmh, my MT03 just totally dies on me. No more combustion, engine totally dead, no more head lights, no more dashboard. I managed to come to a stop without bailing but I could not start it again: same problem as 2 months ago. I have lost my trust in this machine, I think it suffers from some serious problems.

SOURCE: won't start
you have a bad solenoid battery or starter try to ground the starter touch positive to groundwith a rubber ended screw driver if the starter spins you have a bad solenoid

Hi and welcome to FixYa,
Offhand, even if the the stator / charging coil is defective or for that matter even the regulator, the bike should start and run on a fully charged battery. The only problem would be that the bike would die eventually. If haven't been tried, have the battery load tested not just voltmeter test.
Please postback after the load test. Hopefully by then, I would have the wiring diagram.
Good luck and thank you for asking FixYa.
