I have a mercury 60elpt bass tracker. The trolling motor was wired to the same battery as motor overnight. It melted the terminal of the battery and wire from solenoid to starter. Changed battery and left trolling motor disconnected. I changed the starter an recently the solenoid. Now when I connect it to the battery. Starter constantly runs with key out ignition. I took off yellow/red wire off solenoid to check ignition.The starter stays engaged still. Question is, could it be the rectifier or could I have gotten a faulty solenoid from eBay? It wasn't used. Came out the box. Only difference is. It had brass instead of silver nuts. Note I don't have a meter. When I do any suggestions would be greatly appreciated thanks
