Yep. I did the same thing. There's a small rectangular fuse holder inline between the battery and the jack. Open the top and replace the 30 amp automotive type fuse. (the older, larger spade-type)
If you don't have a 30 amp, you can use a 40 amp, in a pinch. Just don't lay on the switch when you reach the end of stroke and overload the wire. But replace it with a 30 amp ASAP.
