So I replaced the speedometer sensor in my M7 because the old one's wire was damaged. I got a used sensor from the dealer off of an unknown model diamond drive. Now when I'm riding the sled the speedometer reads like 160 miles per hour on the analog and digital when driving down the trail, which I know isn't right. Is something else the issue here? or do they make different sensors for different models of sled? don't know if it worked properly before the replacement, I got the sled used.
