Went to start her up today to go deliver Girl Guide cookies. she cranked over but did not start.

After the 3rd try I pushed the boost button she cranked faster but still no start. (I was waiting a few seconds between each 30 second try) second attempt with boost button there was a popping noise when I turned the key and nothing no lights no fan noise nothing.

got out and checked the battery and the negative terminal was melted off and the negative cable was melting the side of the battery! had to put a glove on so I could touch the cable it was that hot.

SO my guess is that the starter was drawing a bit of current and may be on its way out.

I checked and the "hot start" mod has not been done will do that as soon as I pick up a new battery this weekend and make sure all connections are clean.

Would I be farther ahead just to take the starter off and go get it rebuilt now rather then latter? or is possible to be just dirty connections that has caused the terminal to melt?
BTW the battery is a marine deep cycle type and it has had the Negative terminal melted before. (the wing nut part was gone when I got the rig)

Once you replace everything that is attached to something else. It will all be fixed.
