just bought a downed 929rr was 90 percent complete with repairs to get it running but the bike will not rollover, the 3 way clutchdiode in the fuse pack smokes when battery connected. when i dissconnect the oil pressure or neutral switch it doesnt smoke but sparks when i try to reconnect. replaced the diode several times. isuspect that + current isbeing passed through the sensors and if i am not mistaken that should not be. I was told the harness is bad but i suspect personally its the cdi/ecm/ecu. i live in the bahamas and these parts are not cheap so i really want to get a few opinions beforei replace any.

i would also like to know if the dash should light up once the key is on because i only get my instrument panel lights when i push the starter button.
any advice will be appreciated

hey guys started some continuity test and there is a green/red wire in the fuse box connected to the same diode giving resistance on both ground and positive.

check to make sure your fuses are in the proper positions, it should not smoke anywhere anytime unless its pulling too high amps in which case it should blow the fuse, but if there is say a 30amp fuse in a 20amp spot it will roast it like you say. also make sure the main fuse is a 30amp and nothing more. I will check my bike and let you know what i see on those wires that could be faulty. also i had a bad ecu before and it was blowing fuses and i put a 30amp fuse in the 20amp spot(stupid i know) and it burnt up that whole circuit.

thanx i really believe its the ecu but i really want to get the bike up so to spare me the headache i am searching for a wiring harness and and ecu and will cross my fingers on this move. I also checked the fuses as i have the shop manual with complete wiring and fuses. all checks out well. its just the 3 prong diode in the fuse panel that overheats. i also just found a prong that appears to be for the clutch/oilswitch/neutral safety switch circuit that was not connected made that repair but unfortunately the battery kicked outon me gotta get it charged so i will update.

special thanx to firebaldes community and especially hcstreetriding vbmenu_register("postmenu_669082", true); it may not seem like much of a help but you guys got me on the right track and solved my problem.
quick explanation: firstly the starter relay was a honda model but the not the correct onr for the cbr so it was sending the starter current to the ignition guages etc... secondly the smoking diode was beacuse of a short to the ground caused by a short of the b+ on the starter which was sending 12v to the ground which of course caused the short.
i am now in the process of putting the bike back together and rebuilding the starter this was a good learning experience for me thanx for the wealth of info firebladders.
i will soon be showing some more finincial gratitude tothe site.
