Here is the back story. My zxr400 has a rectifier problem a couple a weeks a go but now fixed. However, today when I try to start the r1 it tried to turn over but I couldn’t, tried to use the battery booster to jump start but it won’t maybe the booster is faulty or I didn’t connect it correctly anyway, checked the battery, it was 11.99V, got someone to push and jump start and it worked. Check the battery when engine was running, light off 13.80ish, light on 13.00ish, any 1999 r1 owner can tell me if it is normal or too low? I thought when the engine is running it should be about 14v.
Also, when indicator and break long are on the display light went lower. I am charging the battery with oximiser at the moment and see what happen, it ismy weekend and good weather bike so I don’t use it a lot and I hope it is just a flat battery and not the rectifier or alternator problem.
I just can’t believe the same problem with 2 weeks apart happens to both of my bike and cost me again to fix it.
.At idle it should be between 12.8-13.1.v With lights on and an rpm rise to 4500 the voltage should rise to the mid 14’s then drop back down to 13v that means the regulator is working…
charged the battery for 12 hours and it started as it should and rode home from work this morning, now I am not gonna use it for today and see if I can start it on Tuesday when I go to work.
I just can’t believe how unlucky I am if the R1 goes wrong too and it will cost me again to get it fixed, life is s**t sometime.
sorry about the moan
will post an update for those who interested in my bad luck and care
If the red ‘ignition warning light’ comes on, or stays on, it indicates a variation between the alternator output voltage and the battery voltage. If the warning light gets dimmer as engine revs increase then suspect an alternator fault, if the warning light gets brighter as engine revs increase then suspect the battery.
At 11.99v the battery is flat and needs charging
Typical multimeter readings for a serviceable battery are:
12.6v – 12.8v fully charged12.2v – 12.4v partically charged11.8 – 12.0v fully discharged10.5v under load or dead cell35mA standby current drain by ECU, alarm, clock etc.
Your readings sound a bit low. If you have recently replaced the reg, then Id be looking at the stator output. Its not uncommon for them to fail within a short space of each other.
Yeah - when I was looking to buy a used R1 people said the stator was a known weak point on the bike and was something that tended to fail. So after the usual troubleshooting it will probably be the stator as Scorch says.
If it is the stator it might be cheaper to go for a rewind than a new part?
Yes please. I am free Thursday and Friday so if you around please do drop me an pm and would love to have someone has experience to take a look and hopefully it is some small and silly and I’m worry due to my limited knowledge.
After 2 days since I last rode the bike and it started fine so I guess it was just a flat battery issue. Charging it today again when I parked at work. Hopefully if I look after the battery over the winter everything will be OK but knowing my luck thing gonna go wrong at some point.
