I have a 2004 Honda Foreman 450 ES that I recently purchased, and it has the dreaded ES problems. The owner before me installed a new handlebar switch, angle sensor, and gear shift motor with no success. I jumped the atv with a boat battery to make sure the voltage wasn’t a problem, and still got nothing. It will shift fine manually. Just to add to the problem, my combination meter is unreadable, so can’t tell any trouble codes. Anyone have any ideas?
