may seem like a stupid question, but i bought a half working '83 BJ60 with the intention of giving it some care, and i started into the glow plug circuit and ignition switch that dont really work and im wondering if its because i have an ignition switch from a gasser in it. im a beginner here so is the switch supposed to have a glow setting or is that just supposed to be in with the on. the plug in the last picture looks like the one out of a gas truck. i did a continuity test from the 1980 FSM and it worked like a gas switch and not a diesel. is there anything different between the ignition switch between 1980 and 83 or did someone before me put either a diesel engine in a gas truck or a gas ignition in a diesel truck. also is there anything i can do to make this switch work for me? maybe just wire up a manual glow? thanks guys
