The quad is actually at a buddies house..hes stumped tried checking everything you mentioned..Im not.sure what to do the quad won't shift now so not sure how to move it to take it somewhere else to get it checked out..

It was not blowing this fuse with the old ecu plugged in with the bypass on it..im going to pull the new ecu and put old back in and change the fuse and see if anything changes..

Yeah I've started doing that process of elimination..I have the service manual I just don't know why it's blowing that electric motor fuse after unistalling the bypass it wasn't blowing that fuse before..could it be a bad new ecu?

I haven't tried that yet..what would the carb heater have anything to do with that?

This is the link as to what it takes to install the kit..so just reverse the steps obviously..https://hondaesshiftkit.com/products/00-06-rancher-350-es/

I wouldn't mind footshift..but I just dropped quite a bit of coin for a new oem honda ecu and rectifer/regulator..im not big on electrical stuff haven't found any grounding wires or anything obvious but I'm definitely clueless now..

Before removing the bypass the bike would shift fine every once in awhile..before I took the bypass off and got a new ecu it never blew fuses..the bike would jerk hard when you shifted it probably because it's bypassing the Rev limiter and safety stuff..it would have issues going into reverse and finding neutral and down shifting..

Recently acquired an 02' trx350 rancher es..bike is clean and low miles/hours..prior owner installed a bypass on it because he believed the ecu got wet or damaged and didn't want to fork the coin out for a new ecu..long story short..I ordered a new oem Honda ecu installed it and took off the bypass..bike runs but won't shift..it is currently blowing a 30amp motor fuse instantly when turning the key on..I've double checked the identical plug ins up-front and made sure they're in the correct harnesses..I've replaced the rectifier/regulator Recently still same issue..any help would be appreciated..
