Anyone have any ideas or input as to why or what would cause a battery to drain? The starter, battery, and alternator have all been tested and they are all good. Alternator has been replaced. At start-up battery has about 10 volts, pull battery cable truck dies. Re-start and give her some gas volts run up to around 14, pull battery cable she stays running. Its as though the rpm's gotta be up there before she starts getting anything through alternator. Battery could sit for days unhooked and keep charge but if kept hooked up, she drains all the juice. I have been searching this problem for some time now and thought I found it when I discovered my positive lead had melted on the headers but no luck. Funny thing is that my neighbor is having the same problem with his chevy too. Anyone got any answers??
