I would talk to the service guy at your local dealer before you haul the machine down there. I looked over the service manual...couldn't find anything that mentions a hard reset of the cluster. Batteries are finicky though and sometimes if they die a hard death like that they never come back to normal. Make sure you have at least 12.XX volts when you go to start it up.

 

I had the same exact issue with my 18 rs1. After I drained the battery it wouldn't hold time. I eventually gave up and then a few weeks later it fixed itself. Wish I knew what fixed it.

 

As mentioned, make sure the battery is totally charged up to 14.5. The start and run. The unhook the battery cable and let it set for a miniature or so. Try again.

 

Mine just did this as well. I drain the battery just like you did. Charged the battery up. Then I unhooked both the negative and positive on the battery for 2 hours. Hooked everything back up and worked like charm. Clock now reads the right time every time I turn it on.

 

I took it in under warranty yesterday for the clock problem. Fix was to unhook neg battery cable for 15 min. Works now.

(Somewhat long story, but related) (2020 XP 1K4)

I apparently left my 2 way radio on after a ride. The battery was dead. Automatic charger wouldn't even come on, jump box said no way. I put it on the old reliable brute force charge at 2A for an hour or so, and got the jump box to work.

When it started, the dash started flashing and showed over voltage - 18V!!! Holy crap, I shut it down. I figured the regulator was shot. Or, the battery was shot, with an open (rather than shorted) cell, and without any load, the regulator was confused. So, I got the float charger on it (Battery maintainer), and left it for a couple days. Checking the battery voltage, it was looking good, so waited for the charger to show full.

I tested the battery, and it showed 95% SOC & 95% health. So, I started the machine. The dash showed 14.5V, and my voltmeter showed about the same. I went for a ride, and it was pretty consistent at 14.3-14.6V. I know this is a tad high, so I ordered a new (aftermarket) regulator from RMATVMC. BTW, the battery is apparently a standard Group Size 26, which Rural King has for $50, and Walmart for $60. A bunch of places were over $100, up to $200!

The new regulator put the voltage at 13.8-14.1V, so much better. I threw the old one in the back box with other tools and spares, etc. Never know what you or a buddy may need on the trail.

So, we head out for a ride, and I know I set the clock, but it was off, so I set it again. After the 1st stop, I noticed that it was off again. After about the 3rd stop, I could tell that the clock was stopping when I turned the ignition off. Very Strange! I was ready to just forget about it, it's not that significant, since my phone is on the dash in a Ram Mount, anyway.

For giggles, I searched when I got back last night, and found this and a few other threads, claiming disconnecting the battery for a while fixed the some issues with the clock on other machines, so I gave it a try this morning... I'll be darned! It fixed it.

So, thanks for sharing, and if you read this far, thanks for your patience.

 

My clock stops every time I turn machine off. It’s done this since brand new a year ago. I just thought it was a bad design 🤷‍♂️

 

Are you going to try the battery disconnect trick?
