Question about 1991 Yamaha FZR 600
The FZR is charging correctly with the lights off ( checked with a meter) as soon as the lights are turned on there appears to be no charge going to the battery and the voltage on the battery begins to drop.
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!

Start the bike,and while it's running,Unhook the battery,If it dies,Your alternator is bad,weak or you have a wire off somewhere.
If it continues to run,test the power at the battery cables while they are unhooked,Do this with light off and again with lights on,You should have a minimal drop in voltage + or- 2 volts from the normal 12 volts. Any more than that and you will need to replace the voltage regulator.
Please rate this a fixya
