Working on a project and going to use a glow plug as a heat source (like my 7.3 uses) because their cheap and will be easy to replace. Problem is they get to hot for my application. I'm a machinists and fabricater so the mechanical side I've got down the electrical side, not so much. My question, is there a way to reduce the current flow to adjust the temp? I guess a dimmer switch would be a good example of what I'm trying to do. And no I'm not going to plug it into AC its for DC use. Thanks for any advice.
