Polaris MRZR-D4

[publicenema]

I have entered these part numbers on the Polaris site and get no info. Do you have access to the Polaris Defense site?

I have the parts catalogue.

Just ordered one. Slim chance, but hoping the engine fault codes for these machines in in it. If not, I'm sure its helpful in other ways

So, thanks to publicenema and the help of others on here, my MRZR is running very well. Turns out that the relay/fuse configuration diagram he first uploaded was incorrect, even though this more detailed diagram (he sent me) has the needed slots filled and is correct, and from the same manual. I also replaced two automatic resetting breakers with actual fuses that I could see if blown. That alone got rid of one code, then following this second diagram made the second code go away and got it out of limp mode. Hope my hard time getting this figured out and the help I received here helps anyone else that has an electrical nightmare from fusebox mayhem.

Does anyone know the crossover for the gear selector cable/shift cable? The part number is 7082139 but our local Polaris dealer
says they show it as a military issue and can't cross it over.

Only used on the 2017 and 2018 up MRZR D4's. Your Polaris dealer will not sell you one. If you can't find it on eBay, I can get you one but it'll take a while.

Anyone seen an issue where the engine won’t start until after you press the brake pedal about 20-40 times? when I push the brake pedal to start, you hear a click in the engine bay, brake pedal has to be depressed to start by design, and while I hear the click each time, it won’t start unless i do a rain dance of sorts….
After the engine is started and driven it’s fine for awhile and but eventually starte all over…

Are you attempting to start it with the blackout switch on (all lighting disabled)?

If you're hearing a clicking from the starter solenoid, then it's likely a dead spot in the starter. I would check voltage at starter B+ when cranking and go from there.

the engine doesn’t crank, nothing to do with a dead spot in the starter, it’s as if the truck is being started in gear or like a bad neutral start switch.
if you leave the key in “start” and push the brake pedal, you hear a click, like activating
a switch of some sort, the engine won’t start unless the brake is depressed by design, in park or in neutral.
How would the blackout switch affect starting?

Not a D4, but a 2014 gasser.

Let the restoration begin!

Yes, the starter may click but the starter motor may have a dead spot in it. Since you hear a click (from the engine I assume, and not the power distribution box) I would assume all is functioning as intended and it sounds like your starter is on it's way out.

The unit needs to see brake light input to crank, and with the way they set it up on my 2013 the blackout functionality messes around with that, it would not crank if I had blackout engaged. I never looked into it as I assumed that was by design.

Very nice, mine's a 2013 gasser. Any branding or marking on the black rim you have? Looks like a suitable alternative to the tan ones which are unobtanium now.

It's a factory rim, it's just painted black for whatever reason. I have one spare and the factory carrier that goes with it as well. I am always on the lookout for more, though.

Good luck, that particular rim style was discontinued when they switched to the diesels. On the bright side, the diesel rim specifications are exactly the same. Unfortunately, nothing else in the aftermarket is a 100% match
