This has been a problem since September 2004....maybe someone put a curse on my bike.....I've posted this before, and seem to be a making a little progress (no spark has become "some" spark).....
1993 GSX 600F Katana
Problem: Minimal Spark, almost none....I would assume a bad wire somewhere, but I swapped out an entire wire harness and the problem still persists.
I've studied wiring diagrams and followed the pathways, everything seems to be great (I'm obviously missing something.....). I performed all known (resistance) tests for the signal generator rotor pickup coil, and the ignition coils --- both coils and pickup were A-OK.
SpecialK tested a pair of my CDI's, "both are great" according to him, so the problem isn't there....
Battery is brand new, fully charged.....
I cleaned the ground connections....
The bike was running "fine" before it quit BUT the final weeks leading up to electrical-death she would hesitate from a standing start (low rpm) and wouldn't REALLY snort until the rpms increased (bad alternator...or regulator/rectfier within??)) --- I chalked the hesitation up to a dirty/improperly adjusted carb, but oh wait....I fixed that stuff earlier in the season. -- (the hesistation still could be a carb issue since I'm not an expert)
The day she finally left me....I was riding and the bike lost power (it felt like....say, only 3 cyls firing) and after maybe 5 seconds the problem went away, power returned to normal, I rode the short trip home, parked her for the night, and that was the last ride I ever had; she was lifeless the next day; never spoke to me again.
I am really at a loss.
The only other information(s) that might be relevant at all is:
ONE that the previous owner had the rear signals makeshift wired (jammed a raw wire into the fuse box signal fuse circuit)...this caused one blinker to flash slightly more rapidly than the other....(it has been that way for years with no problem).
TWO, there was an incorrect sized battery installed when I purchased the bike; it was larger (battery holder was modified to fit it) but the same voltage (12V) now I have the stock size installed.
THREE the highbeam indicator seemed to work intermittently, on sometimes, off sometimes (with highbeam on ) but the ACTUAL highbeam/lowbeam works fine (I figure a bad filament in the indicator bulb).
FOUR She quit the day after I returned from a LOOOOONG ride with a buddy. We rode a few thousand Km over a few days; hours on the bike per day.....
I don't know if any of that info is useful at all .....
Oh well, at least I had time to do some painting and fab up some frame sliders (3 per side) -- will post pics once she's back in one piece.
I'm looking for some real help on this one..... I've been to hellandback, and I'm thinking about revisiting.
Thanking you all in advance (again*again)
