I found out the hard way when one of our 07's battery died in the backcountry and we couldn't get it to restart...it ended up being a real late night tow out and no fun at all.
After a lot of research and trial and error I found the problem. Logically most of us think that the battery is an optional accessory and the pull start will be there for a back-up if the battery dies....it is not the case.....
Here's the fix:
You will need to get the wire harness for the relay from the manual start sled....
CABLAGE CONF. *HARNESS-CONF. (Manual Start, Includes 22 to 29 )
515176175
they are a must have because your sled will not pull start with a dead battery, if your battery dies and you can't start the sled you can swap the e-start pigtail harness with the manual start harness in a few minuets.
