Hi the signal wire on the L/H coil on my zx6r f3 hi getting around 5 to 10vlts when the bike is running but the r/h coil is only receiving around 00.5 volts when the bike is running, both power wires are geting 12vlts, the bike sounds as if it only running on three at tick over, if the plug cap are removed from 2/3 cylinders at tick over it makes virtualy no difference to the bike! can anyone help?

Try Ebay, or thefind.com

check coil and rectifier

only one wire is 12v other is neg , coil fires when the neg is grounded not sure if your bike has pulse generator this sends signal for coil to ground at correct time look on you tube for coil test primary and secondary there are two dual fire coils on that bike

Replace the HT Spark Plug leads and caps. It sounds like they are arcing in the wet.
Hope that helps and ride safely.

More often than not this is an issue with the voltage regulator. The easiest way to tell is to get a multi-meter or ohm meter and test it. You can get cheap testers at Northern Tool, Harbor Freight, Home Depot, etc. for about $5. Basically all you do is touch the positive and negative leads of the tester to the posts on the regulator while the bike is not running and the key is in the off position. If the needle moves at all on the meter, there is current passing through the regulator and it should be replaceed.

s/h is okay to use if it fits okay and isnt too rusty

THIS COULD BE WATER GETTING ON TO YOUR PLUGS. TRY A LITTLE SILICON SEALANT AROUND THE TOP OF THE PLUG LEADS TO STOP THE WATER GETTING IN
