Yes, it would. Have a large bucket to catch the fuel and fire extinguisher handy.

Just goes to show how important electrical connections are to the old K. I little corrosion can have a big impact on operating voltages. Try cleaning and deoxidizing all your connectors and earth connections.JayceLane wrote:Not intending to high jack this thread, but have replaced all my blade fuses yesterday. Instruments glowing brighter, engine appeared smoother on start up. For the cost of about a $1. Nice gains.

Overnight at Kollbrunn tonight. Through Germany part of the way, though traffic meant I only peaked at 180km/h. Hit Basel at peak hour . . .92KK 84WW Olaf wrote:Switzerland tonight........

That's what I was thinking but I know little about electronics to say. Probably need a scope to see what's going on there.robmack wrote:.... You have to have a sophisticated DVM to catch low duty-cycle pulses.

That's good news. Inspect that boot really well and make sure its wasserdicht!Hessian wrote:....
On the upside, the FI connectors do not beep when checking for a short . They DO beep from the harness to the plug, so the wiring harness and rubber boot question is sorted

Just want to understand what you've done and verify what you're seeing.Hessian wrote:OK, so I managed to get all of the wires into the plug for a solid connection. Cleaned the earth under the frame (I cleaned the other one on the engine casing previously). Hit starter and getting negative 12 volts but the figure goes up and down. I dont know if thats a negative pulse or what.
Anyway, from battery earth to injectors, Im getting -12 or thereabouts on all four.
The MM is set up to measure DC voltage, thats right?
I dont have a 12V LED lying about, so I'll go and try and find one today from the local shop
Good stuff! You obviously found an LED from somewhere and now you've got a sign from above that the computer is switching in some fashion. To me that sounds like the FICU could be working... "but" you say, "it only works when I have the ground attached to the bike". As charlie says, "this is confusing".Hessian wrote:Well I managed to get some more info before I take up on a replacement computer.
I cobbled together a 12V tester and I'm getting the quick pulses at the injector plugs when hitting the starter. I'm not sure if this is pertinent, but it only works when I have the ground attached to the bike, and not in the left socket of the plug, which I assumed to be a earth as well.
If this is how it's supposed to be, it'll be time for a replacement FICU

Electrics may not have been working. Unplugging and plugging the relay and FI Harness connector has probably righted a poor connection. Soon see when you try to start again.Hessian wrote:.....
So sort of back to square one. All the electrics seem to work, so I've got no idea why the injectors wouldn't spray fuel.

Manometer is for checking the comparative pressure (vacuum) at the throttle bodies on a running machine. Pressure gauge for fuel pressure from the pump or at the fuel rail.Hessian wrote:Well the fuel is pressurised, in that it really shoots out of the hoses if you dont have one connected...
I just havent manometered it, because I don't have a manometer.
