Hi got 1996 cbr 600 parked up for a week went out to start low battery charged. It turned over untill it drained the batt every now and again it would backfire.charged again. pulled plugs no1 fouled cleaned all 4 tried again. No start fitted new plugs coils and leads, no start. pulled leads eathed out with cable to neutral terminal on batt no spark .searched forum. checked pick up ohm reading against haynes manual. side stand up.in neutral. stop switch on it will not turn over engine if off. starting to get a little peed off and thinking itis the cdi. wired up coils common, black/white wire to black terminal on coils .beeped out coil wires to cdi ok. any advice would be great. I'll have to start looking on the dread ebay for a second hand cdi

 

Let me just say that while it's a tough read, your post is one of the most awesome ever! Very nice description of your problem.

Okay, first things first. Have you checked all your fuses?

 

Thanks for the reply. I know its a big read but I did'nt want to leave anything out in case I missed something stupid. As they say a couple of thousand heads is better than one!
Ive checked the fuses and all the wiring connections they all seem tight. I'm at a loss? Next is cdi.

 

Sounds about right...

What about the ground? Do you have a good ground? I would check that and then also check the contact surfaces of one or two harnesess. If they look clean, then the rest probably are. However if they are dirty then there's a good chance that could be your culprit (meaning others are dirty too).

If that's not the case I would defnintely look intothe CDI. I just mention the ground becasue there was another cat here who had problem after problem and never could seem to get the bike started. It wasn't grounded.

 

Checked ground,good continuity on starter and frame, even stripped and cleaned.checkedharness plugs all tight and claen.
Found a cheap second hand cdi so I'm going to try it out!
I'll give an update when I get it and fit it

 

While waiting for cdiI've been having a prod around with the multimeter .
when ignition is turned on I've got 12.8 volts at the coils. Press starter still 12.8 volts.
I thought you would only get voltage at coils when starter pressed?
or is this down to faulty cdi? or have I got awiring fault.
