Basically, it has not seen a change in temp over a certain period of time. Could be a bad connection or a bad sensor. You can take the sensor out and clean the contacts, see if that changes anything. If not, it could be the sensor.

 

Thanks!! where is this sensor located? do you have any pics? thanks!!!!

 

If you pull the battery off the tray, you should see the sensor... I'll try to look for a pic.

 

thanks..if no pic, thats cool. is it the battery by the air intake?

 

Here is a pic of the tray, can't find the sensor off hand.



If you need more, let me know. Shoot me a PM...

 

I believe that they both have them.

Good time to clean the connections on the batteries, huh?

 

my friend hit some major snow drifts, and we think he might have plugged it good under there!! i will be warm, talking him through the pics with my phone.

 

Haha... loads of fun.

Get him to get on here later, let us know how it worked out.
