Recent purchase a 2017 chaparral 203 vortex. Off loaded the boat and drove it to the host with no problems. Went back 2 weeks later and the batteries were dead even though I had the battery shut off switch in the off position. Replaced batteries and now I have codes C-2161 and C2102. After start up the unit is stuck in reverse and shows ” reverse modular error” Please help? From what I am reading it could be the relays on fuse box however I just did a mechanic inspection recheck them and everything passed. We reset the e-reverse relay and it kept popping every time we reset it.
