A good friend of mine has a 2007 Hawkeye 300 2wd and the other day when connecting a battery jump box to start for the first time this year he noticed smoke coming from under the battery compartment and now it will not do anything. I let him borrow my battery charger to charge the battery still nothing, disconnected it and took it to battery plus and they load tested it and said the battery was good. Does anyone have any idea what could be the issue, or maybe the electrical diagram so we can troubleshoot it ourselves. Thanks in advance.
