Also, remember the surge protector has a built-in delay of about 2-1/2 minutes. Or my Progressive does anyway. The battery may be charged and show 12+ volts, but you may want to take it and have it checked under load at a shop. I have had a battery that checked good on volts but didn't have enough amps when a load was applied. You said everything was dead. Interior lights also?

"Happiness? A good meal, a good cigar and a good woman - or a bad woman; it depends on how much happiness you can handle."
