My fzr 600 won't hold charge.


Hi, Anonymous in order to check out any main system electrical circuit, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary.
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 meter 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 meter should read infinity. Connect both leads to the alternator meter 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.

My 1996 Yamaha FZR 600 won't start. The lights turn on, but when I hit the start button, all I hear is a fast clicking sound. Maybe from the digital ignition box. I have tried jumping it from a car...


sounds like the battery to me, have it checked by a sparky, they dont give you much warning before they **** themselves, I had to replace mine only a few months ago

NOT CHARGING..


I dont know about using and tester for autos is going to give a correct reading for your problem i suggest you get a volt ohm meter and check the stator and regulator/ rectifier.

Fzr600 91 model power keeps dying when light on


Are you saying that the battery still discharges when you run with the lights on?
Assuming that the battery itself is good (has it been replaced?) then you may have a problem with the stator.

Start by measuring the voltage across the battery with the engine running and with the lights on - if it is less than 13.5V, then there is still a problem with the charging circuit.
If it does measure that (or better) then your battery is unable of sustaining a charge and should be replaced

You can find some helpful daignostics in this personally authored guide
http://www.triumphrat.net/speed-triple-forum/104504-charging-system-diagnostics-rectifier-regulator-upgrade.html - it applies to any motorcycle witha similar 3 phase generator system.

Good Luck!

Bike wont stay running


If the bikes charging system is not working there will be no power to the coils, and no spark (once the battery is drained). Try putting a good, fully charged battery in the bike and check the charging system.

There are certainly several things that could cause the symptoms you describe. Based on the information you have provided that is what I would check first.

Yamaha FZR 600 not charging correctly with the lights on


I HAD THE SAME ISSUE. CHECK YOUR VOLTAGE OFF O THE MAGNETO, IT SHOULD BE IN THE 25V RANGE. IF THAT CHECKS OUT OK CK THE VOLTAGE IMEDIATLY AFTER THE VOLTAGE REGULATOR, I BET IT IS BELOW 14V. THE FZR IS PRONE TO HAVING THE REGULATOR GO BAD (THE OLDER ONES HAVE NO COOLING FINS AND THEY BURN THEMSELVES UP). THE BEST ONE TO BUY IS THE NEWER VERSION FROM A 1999 FZR, IT HAS COOLING FINS WHICH GREATLY PROLONGS THE LIFE. YOU HAVE TO DO SOME SLIGHT WIRING MODS, BUT NOTHING ANYONE COULDN'T DO. SEARCH FOR FZR REGULATOR UPGRADE AND IT WILL EXPLAIN EVERYTHING! I HOPE THIS HELPS! GOOD LUCK!

Running problem


It takes electrical power to run the ignition system on your bike. If your alternator is not providing that power it must come from the battery. When the battery is out of power, the bike dies. You have a problem in your bikes electrical system. MOST likely is a faulty battery, but could also be alternator or other piece in the system.
