I've had my '70 CJ5 (V6) stored in a barn for the past 9 months. While trying to start it a couple of weeks ago I couldn't get it to run without pouring gas or starting fluid in the carburetor and even then it would only run for a brief period of time. I figured there was a problem with the fuel system so I replaced the fuel pump and the canister type fuel filter. I know now I'm getting fuel up to the carburetor. Because the battery needed a boost from all of the starting attempts I hooked up a charger but inadvertently made the connections backwards. It was only on this way for a few seconds before I noticed the mistake. Now I can't get the engine to fire even after pouring gas/starting fluid in the carburetor. I'm getting a spark (maybe a week one) at the spark plug wires and out of the coil. Is it possible that I fried something in the ignition circuit? Condenser? Coil?
