Question about 1984 Yamaha FJ 1100
Does the bike push start o.k.? if so then measure the static non running voltage of your battery...if its 12v or less then you should replace the battery,( battery life is approx only 2 years) because its probably has a bad cell in it and is not taking a full charge. 12.6v is preferable, 13v is perfect. you can easily check if your battery is being charged properly..gain access to the battery find a good frame ground, no painted surfaces, take a multimeter and touch the positive of the battery it should be about 12.5-12.6v..then rev the bike to 4000rpm and watch the meter climb real fast to about 14 to 15 volts then it will get rectified down real quick to about 13v., release throttle, this is normal operation of the charging circuitry of a bike. Can i get a good positive feedback on this ..thanks!
