SV650 2000 no spark after pressure washing

Hello and before you all star, I know I know. In my defence, I've only just bought the bike. It was used as a courier and it was MINGING. I had it running before I cleaned it. I took off the plastics, removed the wheels and bagged up the ECU and the rectifier thingy.


I have done some tests. Battery is new and charged. I have a new ignition switch fitted as they key was buggered on the old one. I have light on the dash with ignition on. I have power at the coils and if I flash the earth of the coils, I get a spark at the plugs. I have power at the ECU. I got a reading from the alternator plug near the rectifier thingy when cranking.


Where is the pulse generator located? I tried to remove the cover on the left hand side of the engine but it was full of oil. Is the pulse generator located in there? I can only see three yellow wires which come from the alternator coming out of the cover. My diagram shows a green and a white wire too.

Check the easy stuff first - is the clutch switch connector clean and pushed fully home? Worth giving it a blast of contact cleaner.

Have you let it dry out thoroughly? Likely to be damp somewhere which affects both cylinders rather than a fault. from your post I suspect you may have already covered these things but thought it worth the suggestion just in case.

I had a similar incident after it lashed it down all day whilst parked outside work. Come home time, nothing. Dead as a dodo.
45 mins later having brought it inside and blasted the **** / water out of it with an airline.


Press button, go go go....


She just needs to dry out. Hopefully. Good luck.

I washed it a couple of weeks ago. It lives in a dry garage. Immediately after I washed it, I covered everything electrical with WD40. I took apart as many plugs as I could see to make sure. I blown everything out with an airline too.

When you say "No spark" I take that to mean it's not firing when you crank it over as you're said you have a spark when you earth the coils?

Have you tried taking both (or even just the front one as it's easier to get at) spark plugs out, reconnecting the HT lead and cranking it over whilst holding (carefully) the spark plug against the head. Have you got a spark at the plug when cranking over?

ps: when you go to take the plug cap off just make sure the drain hole is clear and the recess isn't full of water before removing the plug.

Yep that's correct. No spark when cranking with the plug removed and held against the head. Plug recess has no water in it. Any ideas how to accurately check the inductive pick up? I asked the electricians at work and even they didn't have a clue!

If you've got a spark at the plug what makes you think there is anything wrong with the ignition side? There is a crank position sensor (or at least there is on a Pointy) that tells the ECU when to fire that spark so I guess that could be suspect but I'd be looking at the fuel side first. Is it possible you got water into the fuel system when jet washing it? How about draining the carbs into a glass and checking.

Edit: Ignore above, I didn't read your reply properly, thought you said you had a spark at the plug....! Duh.

If you have no spark still think along the lines of the system being affected by the pressure wash. If it was working before and isn't now that is the most likely factor. Check the high tension connections betwixt coil and spark plugs. If you crank it over in the dark you may see if the spark is going to ground somewhere it shouldn't. Did you spray water onto the electrics beneath the seat? May have shorted something irreversibly.

Thats a good shout. I'll try that. I'll take the coils right of and dry them
