1986 Trail Blazer electrical

I have a 1986 250 Trail Blazer Odd issue, running fine after lengthy process, hooked up the battery and it will idle ok but the second you gas it, it back fires and runs like crap. Disconnect the battery, runs fine again. bad wiring or short maybe? Any thoughts

First off - the ignition does not need a battery to run - so if connecting a battery affects the running, it may have a bad stator

To start troubleshooting it, disconnect the black kill wire at the CDI unit - connect the battery and see how it runs
