while hunting i used my winch after i got to my duck blind the argo wouldn?t restart. I got a jumper pack and jumped it and got home.i then bought a battery installed it and with the key off the gauge is flashing. with the key on nothing happens.i replaced all circuit breakers and jumped the key switch and still nothing happened.I made sure the ground from the battery to the case was tight and clean. I also unplugged the winch and nothing still Any ideas on what I should try next. thanks
