I installed a led light bar with the Polaris factory relay and after getting it all wired up I turned the key over once to make sure the lights worked and all was good. I checked it again and the quad is totally dead, no powering up or turning over. I did notice that the ground and power wire wasn't fully tight as I had hand tightened them to the extra power bar under the hood and forgot to tighten them. I checked the fuses and they appear to be good, and the battery is fully charged. Any advice or help would be greatly appreciated.
Note: I do have heated grips installed and was using a splitter to connect the heated grips and led light bar to the same orange/white wire.

Thanks for any advice or help.

Here's a stupid question; which of the following Sportsman models do you have?

I have a blue 2018 450 HO 4x4 that came w/o power steering but I had the dealer add it after I bought it.

Get your test light or meter out - start chasing power - connect one lead to the battery neg, check to the pos post of the battery. From there check the pos side of the terminal block - then go to the fuse block - with the key on, use a probe to touch each side of each fuse if any fuse has power on one side and not the other, then that fuse is bad - any fuse that no power on either side, make note of the fuse (amperage and location)

Thanks for the help. Is the fuse block under the hood the only location where there are potential fuses blown? All those fuses are good but when I first turn the key over there is a shorting/clicking sound that seems to be coming from the fuse block or underneath it.

There are 6 relays in the fuse block - one relay is a 'chassis' relay - if the chassis relay is not turning on, you will have no power - all the relays are the same - try switching them around - there is a circuit breaker near the battery ahead of the fan relay, but no other fuses - there are fusible links in the power wires on the pos side of the terminal block between there and the fuse block

Ok, So I checked and I have power to the circuit breaker, and the power bar as well as to the fuse box. The issue is when I turn the key on there is a shorting out sound that comes from the fuse box in particular where the EFI relay is and the Chassis Relay. If I take those two relays out, the dashboard will actually light up but with them in, the dash is dead. I switched the relays around and it didn't change anything either. I am at a loss and appreciate any advice or feedback.

Unplug the ECU and see if it will power up - the EFI relay gets it's ground through the ECU, but the chassis wiring relay gets it's ground directly at the power block - if it powers up and the relays quit clicking with the ECU unplugged, then you probably have a faulty ECU - that would have to be verified by an electronic diagnosis of the system performed by a dealer.

If you don't know how to unplug it, take it to a dealer now - it has a 50 pin multi pin plug with a lock or two to prevent it from becoming loose or disconnected during operation - you release the locks and unplug the connector just like 80% of the other connectors on the wiring harness.
