Release brake message

I replaced with 3rd party. The first failure was the OEM. I spoke to the shop here and he agreed that it is most likely the parking brake. He said Polaris has had issues with trying to add their own version but always ran into issues with the brake sensor.
Ah ok. I think it must be the luck of the draw on brake sensors. I have the spring brake thingy on my Xpedition as well and I’ve used it a fair bit while transporting the machine still no issues with the original brake sensors. But we did have to replace my brother’s.
 
I’ve replaced 3 of these on my rig so far and have determined a couple things.

1st one I replaced the rig had 12 miles on it. First ride out went into limp mode. I had to create a jumper to get it started again.

2nd one replaced was after I installed the parking brake. This was months after and thought maybe it was a bad unit.

3rd was the one that made me realize the parking brake was creating to much pressure for long periods of time. (Hauling on trailer). This would cause the brake fluid to eventually leak through the rubber seals inside and touch the brake sensor.

I’m going to be adding a kill switch to this setup so I can continue using the parking brake, and no longer worry about the brake sensor every time I’m in the back country.

FYI- a fuse can be used as a jumper in the field to get the rig started and keep you from being stranded. Having some wire or anything as a jumper will save the day- I’ve learned the hard way lol.
Can you explain to me how you used a piece of wire or a fuse as a jumper?

So I carry a spare fuse and wire kit with me at all times. This little two prong wire connector worked perfectly when I was stranded about 150 miles from home.

Disconnect your brake sensor and put this prong in to the sensor. It acts as jumper completes the circuit which allows the machine to start. Sometime you have to fiddle with the prong just right. But I’ve since replaced the bad sensor, however this prong stays in the glove box just in case!
