I thought the battery might play a part. I disconnected it upon advice that it would drain the electro lights while hooked up to shore.

Run the next time that person gives you any advice!

The converter should supply house loads (ie lights, etc) and charge the battery. And you need and want both.

One important step and to often overlooked is to know the condition of your batteries. Have them load tested, often free at a auto store.

For about $10 you can buy a voltmeter and check your voltage which would provide you and us so MUCH more information.

Loose connections, solder issues, burning smell, etc. posts from you and others are all good and need to be addressed.
