hello to all newbie here
i just bought a 97 cbr 600f3 not running 1st problem is when i press the start button it doesn't crank at all i have voltage going all the way to the solenoid but no crank. 2nd problem when i jump the starter at the solenoid and the bike turns over it starts then dies the spark at the plug comes and goes i may get spark for a minute then i don't get any spark all fuses have been check and are good. batt is brand new. also where can i get the wiring info for this bike.??thanks

 

ok first update for the no crank over when hitting the start switch found a bad connection from the clutch handle switch black wire
but still no spark.??any suggestion what to check for no spark intermitten

 

sounds like maybe your coils are going bad ... when they heat up .. the resistance in them is going up......... causing a no spark situation....

even over night and trying it in 1st am still no spark so right now it makes no different in temp

 

But you said you fixed the crank issue but the intermittent spark issue still persists....... so you said it worked then stopped working .... so if your not getting any spark... check all the wiring to do with the ignition system....

thanks but you are mixing both question up.
i fixed the 1st issue no crank from the start switch or button.
now that is fix. now i'm trying to resolve the 2nd issue intermitten spark
what would cause that more the r/r or the ignition control module.??

 

Sounds like a problem with your pulse generator. Check the service manual for the proper resistance, and measure it when its warmed up. The resistance WILL change as it heats up, and this is when most pulse generators fail.

 

ok i can't get the bike to start so all the components
are ice cold so the theory of parts failing under heat does not apply here.
i check the diode rectifier and i get 0.411 is that good.???

 

. . .Are you referring to the R/R? And .411 what? Ohms? Volts? You've got 5 lines comming out of that thing, how did you get ONE reading? Was the bike running, or off when you did this? Please be more descriptive with your testing proceedures and findings.

 

i have no idea why i was told to check the r/r when all that is for the charging system. so i guess the 2 items that i should look for for no spark would be ignition pulse generator and ignition control module and maybe coils.
is there a way to test these 3 item.??
