I have a 84 cj would not start replaced ignition mod. Starter, starter solenoid, new battery, cables. Turn key to a/c position reads 14. Move to start no sound drops to 10. Thought the battery may have low charge so hooked jumper cables to battery went to start jeep acted like it wanted to start but did -not turn over. Tried to turn it off would not-stop trying to turn over had to remove battery cable. Anyone have any suggestions other than taking it to an electrical shop. Thanks in advance
