Re: Electrical Help CBR 1000RR!!!
Couple of things to check. The headlights are turned on by a relay that is located right next to the fuse box. Remove each relay one by one and test these relays. I know that two of them are for the ignition/fuel injection system and i know one of the others is for headlights. Use a battery on a test bench and pic the relay. Apply 12vdc to the two like positioned spades and the other set should change from open to closed. If one is bad replace it and i bet the bike starts. The battery issue could be the regulator/rectitfier. It is just back from the fuse box. Get the bike started and unplug the two wire red/black harness. Meter the output of the r/r and make sure it isnt overcharging the battery. Thats most likely the hissing you hear. its overcharging the battery, the contents are literally boiling from the heat. 13.8 vdc is what you should get. If it is much over 14 thats too much. each leg of the stator should be about 14vac to ground. they should all be within 10% of each others voltage when reading them to a ground reference. Hope this helps!
