Have you looked into becoming an Instrument Technician? It's halfway between electrician and engineer. You can start with a contractor and if you're any good at all a manufacturing company will "poach" you from the contractor. If you're good at that, it's a straight shot to Maintenance Planner, then Maintenance Manager. I'd expect that trajectory to take several years, but you're pretty quickly out of the bull work and your tool bag will be much lighter.
