Hey guys, not new to the forum just had to create a new account due to my computer croaking. Anyway my ATV sat for a few months and I went to crank it and heard a clicking over the battery. Removed the seat and noticed a rats nest over the battery and wires. The top 3 wires of the middle harness on the ECM were chewed in half as well as a green and yellow wire running together into a quick connector of some sort. I spliced them back together and replaced the battery. I knew it was weak because cold weather made it not want to shift gears like it should, but only in cold weather. Warm weather had no issues. Now it wont shift out of neutral. I crank it, shift up, the dash goes from N to 1 and the atv jumps forward like it should, but then it falls back down into N. I hear the motor shift and it sounds reasonably normal. But no error codes or blinking gears on the dash. Could this be a shift sensor possibly fried from the short out in the wires when i tried to crank it? I've never replaced the sensor or the shift motor, and I still had the factory battery in it. 250 hours on machine, 2008 honda 420 ES 4x4 i bought new from the dealer. Please give me a starting point?
