2007 Arctic Cat 700 efi 4x4 - Wiring Issues

[perryz]

hi everyone i'm new too all this. and happy i found this site.

here is the problem i'm having with my cat.

few months ago i went to start the cat and no power nothing came on.

so after reading few posts on the net . i suppiled power to ingnition and got power to it.

but no lights. ok fine. drove the bike like that during the days only.

now power still there but does not start. ok thought it with the ing switch. replaced it and still the same. fuel pump does not go on or i can not hear it.starded checking all the fuses and they are all fine.so i provide power to the fuse for the the fuel pump and can hear it come on

hit the start button and the bike starts. give the power to light fuse and same thing they come on. checked the power to main fuse and the power is there coming in and going out.

what seems to be the issue? if anyone one can help before taking her in.

Thanks.

Check the main wiring harness where it goes down from the handlebars and under the rear plastics where it goes around the frame. Check for areas where the wires may have rubbed thru.

first of thank you. now are you thinking a broken wire. now if that was the case would i still get power to ing if i give power to ing fuse? just wondering.

thanks again

It sounds like a broken wire from the fuse block to the front harness. 2007 models are known for wiring harness problems. I know, I have repaired both the rear and front harness already. Look at this post

http://www.quadcrazy.com/atvforum/arctic-cat-atv-forum/10091-extract-print-arctic-cat-atv-schematics.html

This will help if you print out the schematic on several pages so it can be seen better. I would start following with the meter to see if the ignition switch has power to it from the fuse block. The wires that snake up to the handlebars are notorious for breaks.

The first picture is the schematic printed on 6 sheets of paper and taped together. This larger print makes it so much better to see the wires and notes. The second is what I had to deal with a few months ago. I blew out about 12 wires in my front harness.

once again thank you guys for helping me.

ok so this is what i have done so far before i open up the whole bike apart.

took power from main fuse and provided it to the red wire on the ING. then took power from the light fuse and provided it to the grey wire on the ING. then took power from the red/black wire from the ING

and provided it to the fuel rely and the bike works .light come on when needed. bike runs and can turn off and run. the only thing is that the dash flickers on and off. please guys tell me if the rout i took is ok or not. or is there any other way of connecting the wires like that.

what i think is that it is the 3 ING wires that were broken somewhere.

sorry i have never worked on a bike before.

If it was my bike I would take the time and pull the plastics. If the ignition wires rubbed thru then it is only a matter of time before something else shorts out and you end up with a mess like Mike did above. If you need advice about removing the plastics let me know. I have it down to a system and it takes me less than an hour to get them all off.

[perryz]

Yes please let me know how to take the

Plastic off

Thank you again

[swampcat07]

Remove the rear rack - 4 Main Bolts

Remove the bolts that hold the foor rest on.

Remove the battery cover

Remove the battery (negative cable first)

Disconnect the tail light and take off the gas cap.

The plastics should come off. Check where the wiring harness leaves the fuse block and wraps around the frame.

For the front remove the cover for the radiator and the cover where the steering stem is. You should be able to see almost everything from there.

Let me know if you find any bad wires.

Ok thank you will give a shot later Ann

Will keep you posted.

Thank you again

You have a broken wire somewhere in the front harness to the pod. Once you repair it, wrap the harness in spiral wrap like I did and it will save the harness from future problems.

Thank you guys for all the help

It was broken works behind the rear plastic

Actually corodied wires. Fix them

Everything up and working. Except for the

Fuel pump it does not come on unless

I bypass it. But then the start fine but when

I ride it it runs like crap ? I guess it's

Due to pump on none stop and makes

The bike run rich and sluggish checked

Wires and nothing else is broken

What is my next step guys?

What else can I do?

Thank you all for the help for getting me

This far

What do you mean "bypass" it? which wire are you bypassing and what are you doing? Supplying power to a lead for the pump? A quick check of the schematic I would look at #14 to see if that is reading properly (12 ohms) I would also clean the connection to the CDI box, it feeds a signal out to the pump and it may not be getting that signal. Also check #13, maybe the fuel level sensor isn't working.
