If you are a car mechanic then you would know where to start. Just because the engine revs higher and there are 2 less wheels and you are exposed to the elements. Does not change anything really. Not trying to be an ass or a dick but if you are a mechanic like you say you are, you should be able to figure this out. Or take it to a professional. I would first start by un-mickey mousing your fuel pump ground/wiring and get it back to factory condition in that regard and move forward from there. Check for proper voltage and resistance in that wiring. Start at the obvious first.

 

just cause I'm a mechanic doesn't mean i don't have weak points. where i work i do a lot of parts changing not diag. how would one restore it back to factory after its been altered>? besides buying a harness.

i wish i had a picture to show you.

 

Is it the fuel light flashing or the red FI light?

 

fuel light flashing

 

Maybe a weak fuel pump due to a bad ground?

 

Need gas? :O

 

Ive had my fuel pump earth burn out too:

There is that other black and green wire going to the same connector that is for the fuel reserve switch.
If the flashing fuel light is random/sporadic thats likely the culprit.

 

that's pretty close to what my harness looks like , im going to take pics tonight.

 

Motorcycle Connectors


one of many sources for oem connectors

 

if just my ground Is bad , wouldn't it be easier for me to just snip the ground before the connector and crimp that to a wire going to my negative on my battery?

 

apparently this problem is more common than I realized but it seems no one is straight forward on the solution, from any of the threads I found.

the other 2 wires on my fuel pump harness are slightly charred but don't look like they would be "bad". do you think I would need to replace all 3 wires?

 

All a wire does is pass electricity. Find a way to make that happen and you should be ok. If its slightly charred I would clean it up and put it back on.

 

clean it up?:eh:

 

She I fixed my one I went through all the wires looking for damage. When I found something all I did was cut the wire slip some heat shrink on and join the wire back together.


I think what caused mine to burn out was the cable kinked. There is a pretty sharp angle in the loom at this point.

 

See my ground is bare wire all the way to the connector.

I dont think i can clip and splice quite like that. Maybe if theres other damage too but my ground is toast. Im going to replace it with same guage wire , but cant seem to get the wire out of the clip, any tips?

What i have read is that its most common to happen by the gas tank and positive making contact

 

I had to replace the entire earth wire.
I used a very small electrical flathead screw driver (about 3mm head on it).
Push this into the connector and use it to push down on what is basically a latch to stop the wire from coming out of the connector.
It's not particularly easy and it's quite awkward but easier than replacing the entire connector

 

Easy enough i got it done , didnt have the connectors i need at the store so i used a wire out of my old broken headlight it had the same end as the one i needed and looked shiny and new! Hopefully i can get it back together tomorrow and seeif it solves my issue

As far as i can tell the ground wire is the only one that burned the other connectors all look good if i shine a light inside them.

 

well I used a ford Taurus harness to get the connectors I needed , soldered my connections and put in 2 new wires going to the fuel pump plug. she runs like a dream again. woohooo thanks for your help guys! I now understand wiring a little better, so I learned something.

 

Good for you. Happy for you. So no more problems?

 

Best part is i only have about 2000 in the whole bike so far with only 7k miles

 

Hey man, I have the stock exhaust from my bike laying around if u want it. Just pay shipping and its yours.

 

done and done
