Thanks to all those posting. The motor was switched with 30 amp rated power relays, that the the windlass manufacturer insists theyve been using without problems-I am very doubtful. The failures were complete meltdown of contacts, and I immediately suspected improper switchgear for the app...
Thanks Scotty, The motor runs but the switching relays are failing every other month. I believe that this is due to inadequate relays for this app and I have already spec'd and ordered replacements, but I wanted to make sure that the lack of a cap wasn't a contributing factor, and that the...
