Question about 1992 Yamaha FZR 600
Where does the gray and white wire go on the ignition switch
Hi, 77waterman in order to diagnose the starter circuit you must start with a fully charged battery, 12.5 volts or better and be able to pass a proper load test if necessary. The battery cables and terminals must be clean and tight. The "NEGATIVE" cable is famous for corroding and or breaking inside the harness, check the connectors at both ends. Check your starter relay with a test light for continuity, it could be faulty due to corrosion and sticking in a closed configuration, another claim to fame. Finally, there is the starter solenoid, low battery voltage or faulty battery connections will cause extremely high amperage at the plate and contact shoes and rob the hold in coils of much-needed voltage. In extreme cases, the solenoid plunger plate will literally weld itself to the contact shoes, keeping the circuit closed and thus permanent engagement. Another scenario is unacceptable voltage drop to the starter solenoid from the ignition switch to the starter relay to the starter button, and finally to the solenoid. Remove the green wire from the starter solenoid and hook up the positive lead of your voltmeter to the green wire connector and ground the negative lead. Turn on the ignition switch and depress starter button, the voltage reading should be no more than .5 volt less than the battery voltage. If it is more than .5 volt you need to backtrack that part of the circuit with your volt meter until you find the voltage robbing offender. Next, remove the 3 screws that secure the solenoid cover and remove the plunger, dress the plate and the contact shoes of arching residue and make sure the contact shoes are tight and secure. If you have done all of the above, replace the green starter button wire, hook up your voltmeter to the battery and check the voltage drop when you start the engine, anything below 9 volts could indicate a faulty battery and a proper load test should be performed.

Hi and welcome to FixYa,
A number of possibilities but initially, check/replace the voltage regulator or the connector.
Good luck and Thank you for using FixYa.

I have had several bikes in my time. and keeping the carbs syncranized is very important. Did you put aftermarket pipes on it? try rejeting the carbs up 2+mm that may help the fuel air ratio?

Sounds like your regulator/rectifier is faulty....but it could also indicate an alternator problem. Don't run the bike or it will eventually hurt your battery and/or your alternator (if it hasn't already.)
The wire currents, voltages, etc needs to be checked (from the alternator AND from the rectifier) so I recommend you take the bike to a mechanic unless you have a multimeter and shop manual handy.
I've found Yamaha wiring connections to be slightly weak....and sometimes lead to the premature death of the reg.rectifier. Solution was to 'solder' the connections instead.
Good luck with the FZR.
