The previous owner of my Bennington installed a Trac T10109-35 anchor winch. I never tried it until today. It’s supposed to be a free fall after pressing the down button but it won’t release. The retract function works fine, just not down. Ive manually unwound the line to make sure it wasn’t bound, but still won’t release. Looking for suggestions. The manual is useless. Also there’s a small button between the up and down I thought might be a reset button but still no down. Maybe it’s just a bad switch but the units only a year old. Help!!!
