Hi. I just bought a used boat with a two-year old co-pilot minn kota riptide motor on it. When we took it out for a test drive before i got it, the remote controls worked fine on it. Now, 2 weeks later, the motor doesn't seem to respond to the remote controls. The batteries are fully charged and the motor connections are all alright. It just seems like theres a problem with a link between the remote controls and the motor itself. Anybody have any pointers or know a link to an owners manual for this troubleshooting? Thanks.
