Funky Gauge

Dear Ralph:
I was wondering if you have heard of any problems related to faulty ECMs in 2004 Firecats. I have a 2006 F-6 and from day one when I bought it the speedometer would occasionally go crazy fluctuating, or go out completely. I was told to check the voltage regulator, which I did, and it was fine. So, my local dealer said it could be the ECM. The problem with the gauge was getting worse and worse towards the end of last season. Thanks in advance for any advice or direction you can give me.

Arctic Cat did have some issues with the 2003 gauges, but they came back in 2004 with an improved version. If your problem was the voltage regulator, there would be other problems as well; like, the DC section of the ECM would be fried and the power valves wouldn’t work and the sled wouldn’t pull over 7,000 RPM, or all of the light bulbs would be blown. Nor should this be caused by the ECM. The gauge assembly needs to be replaced.

I am a bit curious as to why this wasn’t fixed immediately, under warranty, if your sled had this problem “since day one” as you state. Now, unless you have a extended warranty, you’ll likely be paying for the repair unless your dealer knows full well the problem has existed since day one.
