I just bought a used boat and it has a 24v motorguide trolling motor... Took it out twice and the second time I used it it died like the batteries were dieing so I charged the batteries and nothing. I've replaced the plug and outlet because the 1 prong was burnt on the end...still nothing....I've tested the batteries and have 12v....tested at the breakers they seemed good....I test at the plug and there's nothing but I used a jumper to test each wire strait to the batteries and get 12v off each wire...don't know if the trolling motor burnt out or a wire....I'm not much of an electrician so I need help big time
