No power issue 1969 Caprice
I have a 1969 Chevrolet Caprice that has a absolutely no power! It won't crank or no lights what so ever.... It sat in a barn for 20 years and critters chewed wiring under the hood.. Wiring from fuse panel back seems to be ok. I have replaced engine harnesses and still no power. Battery is good. Have grounds to both engine block and body and still nothing... Fuse panel seems to be ok. I am not very good at tracing down wiring issues. Help!
