long story short, last Sunday coming in low voltage alarm goes off and starts shutting the motor down, pull into spicers, run and get a spair battery from the camp, it did not come right off a charger but showed 12 volt on a meter, cranked right up and ran fine back to the camp, asked a friend to crank it yesterday before I drive down from shreveport, won't fire but turns over fine, checked the fuel sqweeze bubble there's fuel, grabbed the nuts on the battery to exchange it and it's red hot, the negative pole being the hottest. Is this one of those fuse problems that protect the computer from low voltage? Anyhelp or advice would be greatly appreciated. It's really hard getting things fixed 200 miles away.
