What are my readings supposed to be on a 12v system? Currently, if I push the glow plug button, I get 11.38v across the posts on the battery, 9.1v on the post the wires connect to by the fuel lines & plugs themselves are between 7.8v & 8.4v. The voltage on the plugs rises as they heat. I'm going to venture a guess that happens due to less resistance as they heat? Are my numbers reading correct or is something wrong? Maybe the original wiring ist kaput on my 560? The battery is fresh. One other thing, what is a safe amount of time to leave the plugs energized? They're new & I would rather not fry them out.
