What are the chances of a bad ignition switch? Had that leave me fumbling to create a jumper to get home once. Now I carry a spare $12 Amazon clone.

Post #10 gives you the steps to check ignition switch. But if you have a spare ignition switch (amazon clone) might as well connect it and see what happens.

Yes I have 11.8 v
And also when I apply the brakes I loss power to the DG/WH going to the solenoid.
I tested the Brake sensor I get continuity when applying the brakes. And I also get continuity on both terminals of the wire harness. Is that correct?

I have 12.6v now and still the same problem
To recap
When solenoid is pulled in I have power on the DG/WH. I apply brakes loss power.
if solenoid is unplugged no power on the DG/WH
I inspected and swapped the relays and they seem good.

as stated: Solenoid unplugged, key in START = NO 12v on DG/WH at solenoid plug.

Leaving solenoid unplugged:
  1. Is there power at other end of DG/WH wire coming out of ignition switch, with key in START position?

  2. Is there power going into ignition switch on the RD/DB (red/dark blue) wire, with key in ON position?

Harness plugged into ignition switch, Key in ON position:
  1. NO power on RD/DB wire
  2. YES power on RD/WH wire
  3. Does fuel pump cycle on?

Fuel pump cycles when key turned to ON, and cycles again when key turned to START?

With the solenoid harness plugged in
Power on the DG, RD/WH & OG
This is with key in ON position?



With key NOT in ignition switch, which wires have voltage?

May be bad ignition switch, or wires in wrong location in ignition switch plug.

This is ignition switch test from 2011 manual.

If switch tests good, verify wires are inserted in correct pockets in plug body.

Jay,
You must be very frustrated with this electrical challenge. I know I am, and it isn't even my RZR.

Ignition switch tested good, wire are in proper spots, relays seem to be ok, fuses all good, and it does not function properly.
If you jump the solenoid will it still fire right up?

Is there a missing part of the story?
Did you do ANY maintenance or mods to your RZR just before this issue started?
What was the initial problem that caused you to replace starter solenoid?
What happened to make you think the ECU might be damaged?
What was the incident that caused you to have to jumper the ignition switch?
In post #25 you state "When solenoid is pulled in I have power on the DG/WH." How did you pull solenoid in?

At this point I would start lookin at wire harness for damage.
There are splices buried in the harness that have caused problems for others.
Take a look at this thread:

Any signs of mice? Friends of mine have spent thousands on tractor wiring because of mice. If everything was fine before storage, it's got to be something simple that maybe you did or happened while stored. Hope you prevail.

Hello everyone, I'm new here and this is my first post.

Electrical gremlins are the worst in my opinion. Interestingly though, you state you lose all voltage to the solenoid when you step on the brake. This indicates there is a short somewhere in your brake wiring which is drawing all current because current will take the path of least resistance. Follow your brake line wiring to see if you can find damage to the wire, pinched in a certain location, etc. If you don't see any external damage on the wires (pinched or burned through from exhaust, etc.), check the ground wire for the brake light and make sure the hot and ground wires aren't damaged somewhere and touching.

Hopefully you get this figured out and can update us as to what the cause was.
