Hi. I have a '76 F-150 with the 4.9 300 6L. I rebuilt it and has 1000 mi. Problem: right after rebuild, under a load, it wants to spuder out and if I keep on it it will backfire out the exhaust. One day, when starting at a store, it's dead. Check under the hood and my negative battery connector has melted itself in half. Months later, as in yesterday, I get the solonoid to click or just 1 hard click from the starter, as if battery is dead. Jumping does not work. I even notice there's no draw coming from the running vehical when the jumper cables are connected. Eventually it starts like it has a full battery charge without a jump. Battery load tested good. Alternator tested good 4 times. Has brand new starter, solonoid, voltage regulator, battery cable/connectors and ECM. Please fro the love of God help. I'm at a loss.
have the same problem?
