after driving home no trouble except that the gauges kept acting up put it in my shop and put a meter on it the findings are that the battery begins to recover the instant you stop the drain, sutch as trying to start it. thats what happens when you use a realy good battery. The one in this car is as heavy as the battery in our big rig. I think it may be strong enough to start that 600 hp diesel. The completion of the story will be posted after the alt. arives and I have tested the system. as of now the battery is on slow cook at 2amps.
