2011 rzr 800 no power with turn key

I was going to fix the water pump seal on my 800 today and I go to start it and Ive got nothing to the key turn. I started with the easiest which is the battery and if it was dead. Checked it, 12.2 volts. So I went to the fuse box, checked them all and none that I checked were blown. So next was the ignition switch, checked all 4 wires with a test light and there's no power to any of the 4 wires. So where do I go from here? Do I have to dig through the main harness for a broken wire or is there a fuse box I'm not finding? Is what I have pictured the possible culprit of not have any ignition power?

Re: 2011 rzr 800 no power with turn key

That looks like a fusible link, another name for a high-amp fuse. Either disconnect one side and check it with an ohm meter or check from each side to ground for 12 volts.

But first, on frame behind driver's seat, find brake pressure switch. Pull off connector, jump it.

I don't have power at all to the "dash" the cluster isn't lighting up at all with the key. I don't the the brake pressure switch is the problem. I wanna say it's the ignition switch but I don't even have power to the ignition switch.

Is that "fusable link" factory for the 800's or did someone put it on afterwards?

Step 1. Clean that swamp donkey so you can proper diag.
Step 2. Key switch should 4 (possibly 5 depending on year), check the continuity of the C and D wire, those are the "on" wires.

88 Red goes to "red splice" and the fuse box.
91 goes to "red white splice" and that loops through a 20amp breaker.

You have juice from the battery to the fuse box?

Re: 2011 rzr 800 no power with turn key

Those look like two thermal reset 50 amp circuit breakers, that have been added to RZR.

What are the red cables connected to?
One to battery, and other to starter solenoid?
Can you post picture of their backside? I suspect they are wired in parallel to provide 100 amps.

They are similar to the problematic fan circuit breaker that Polaris uses.
They do not play well in a damp location, and it appears yours are locate below the average waterline of your RZR.

I would start with volt meter at battery (12.2v you said) and work your way down stream till voltage dies.

Re: 2011 rzr 800 no power with turn key

I assume you made the fuse checks with your test light so that you know power is there. So you have a problem between the fuse box and the ignition switch. I would check the fuse that supplies the ignition switch to be sure it is contacting both contacts in the fuse box. checking the top of the fuse with a test light wont reveal if the spade is not contacting the rest of the circuit. If you have power coming out to the wire but none at the switch, bad wire.

Re: 2011 rzr 800 no power with turn key

I am aware it has no power at all. Wire come off the battery to the solenoid, then from solenoid to starter. But there are 5 small wires that go to other things, dash, lights, fuel pump? Ignition? That also comes off the solenoid. Had that eyelet break on my old 800 and also on a 900s. I lost all power. No lights radio nothing. Simple to check...
