Polaris Speedometer Repair - Part1

In this video we troubleshoot and start the repair process for a 2001 Polaris Expedition 425 Speedometer. This belongs to a friend and it is interesting how this works. After looking into these, It seems to be a common failure on them for running them with a bad battery or no battery. It seems the voltage charge regulator may cause issues with the internals of the speedo. Another bad deal with no speedo is that the four wheel drive enable comes from this speedo as well to make sure the vehicle is at zero speed before shifting. I share in this video how helpful the site was for KA7OEI's blog in helping me identify the burnt resistor on this board. The site has lots of help on these and I highly suggest checking it out if you are having the same issues. I will try my best to go further with this repair and see if we can still get this one back going after 7 components at this time, we still have more failed components to go. I will post a part 2 of this speedo repair as long as the Main Microcontroller is not dead. Hope you find this video helpful and thanks for watching!
