Vitalii Posted June 26, 2020 Share Posted June 26, 2020 Hello everyone! I decided to make a little cleanup to my bike and now need some help with it. I found that connections on the right side (see picture) were oxidized and the connector itself was in bad condition. Found on internet that this connector should be soldered (as a wiring improvenet tip) - and decided to make the connection without the plastic part. The problem is, I did not disconnect the battery, and managed to short green and red wires. It sparked for a second, then stopped. After that, when I turned on the bike, the fuel pump did not produce its sound. Self-check passed fine, startor works as well. FI indicator blinks only when startor rotates. Could you suggest what were the wires I shorted and what may have burned out? I'm going to take a look at the pump itself today, what is a safe way to check whether it's alive? I thought first on FCR relay, switched it with the headlight relay. Did not change anything, I assume FCR is fine. Link to comment Share on other sites More sharing options...
Member Contributer Grum Posted June 26, 2020 Member Contributer Share Posted June 26, 2020 Think you should check MAIN FUSE B 30amp. Located next to your Starter Relay. Shorting the Red and Green on those wires will certainly take out that Fuse. This kills the power to your Fuel Pump and main power to the ECM etc. Hopefully replacing the Fuse should have you up and running again, no problems with your Fuel Pump. Good Luck. Let's know how you go. Link to comment Share on other sites More sharing options...

Well, the fuse was indeed blown, but replacing has no any (visible) effect. What else I could check? Link to comment Share on other sites More sharing options...

What else I could check? Is your Battery charged? With Ignition to ON and the Red Kill Switch to ON(RUN). Do you hear the Fuel Pump prime for 2 seconds? Do you have a multimeter?

The battery is new, I've been using it for a month. No, I can't hear the Fuel Pump Prime Yes, I have a multimeter Link to comment Share on other sites More sharing options...

You need to measure the voltage at Main Fuse B. You should see 12v at BOTH test points on that fuse. Black meter lead to Battery Negative, Red lead to probe the fuse test points. What do you measure? Get back to me as soon as possible so we can move on. Link to comment Share on other sites More sharing options...

On your picture notice the single wire connector below your fuse, unplug the connector make sure you have 12v on one of the connections. Is the wiring to that connector good? The fuse and wire connector look burnt and not in a good state. Also please confirm you have the Kill Switch in the RUN position.? Link to comment Share on other sites More sharing options...
Vitalii Posted June 27, 2020 Author Share Posted June 27, 2020 Yes, there is 12v on the single wire. Wiring is good, the circuit between the fuse and red-white wire is short. Also I have 12v between the wires I have initially shorted. Yes, kill switch is in the RUN. Link to comment Share on other sites More sharing options...

Now we need to make sure the 12v at your fuse is getting to the Engine Stop Relay. Locate the ESR and remove the relay there is a Black/Pink wire you can see this goes from the relay to bottom wire of the 18P plug, then becomes a Red/White wire which goes back to your Main Fuse B. Can you see this on the drawing attached and the drawing on my first post? You must have 12v at the Black/Pink wire at the ESR, probe the relay socket for that wire. Also with Ignition to ON you should see 12v on the Black wire of the relay socket as well. What do you measure? I also assume you have the FCR inserted, Yes? Have you got the full wiring diagram of your bike? Link to comment Share on other sites More sharing options...

Here I have 12v between black-pink and black. When ignition is on, this voltage drops to zero, voltage between black-white and black goes to 12. Yes, FCR is at place Link to comment Share on other sites More sharing options...
Member Contributer Grum Posted June 27, 2020 Member Contributer Share Posted June 27, 2020 You need to keep your meter black lead on Ground Battery Negative terminal. Red lead on the Black/ Pink you should see 12v. Ignition to On you should see 12v on the Black wire as well. Recheck this. Link to comment Share on other sites More sharing options...

Checked again, it's right. With ignition off only black-pink has 12v, with ignition on both black and black-pink has 12v Link to comment Share on other sites More sharing options...

Listen closely do you hear the ESR click to energise? If not replace it with your HiBeam relay. Link to comment Share on other sites More sharing options...

The relays are good though: I can hear them both clicking when they are at hi-beam's place Link to comment Share on other sites More sharing options...

It provides the ESR relay coil with a Ground on the Red/Orange wire to energise it. Link to comment Share on other sites More sharing options...
Vitalii Posted June 27, 2020 Author Share Posted June 27, 2020 Yeah 😃 the wiring was fine, but the sensor was disconnected. I may have unplugged it when was taking off the front plastic. I'm on the road again! Thank you for your help! Link to comment Share on other sites More sharing options...

That will definitely kill your bike. Glad you have it sorted. It's 1am here, time for bed. Cheers. Link to comment Share on other sites More sharing options...
