Thought it might be time for me to contribute something that made an engine chore a little quicker. Wanted to make sure all 3 glo plugs on my MX25 were heating without disconnecting all the wiring and measuring with an ohmeter etc. Used my clamp on ammeter to measure total glow plug current to all 3 and got a little over 16 amperes. Then disconnected the easiest glo plug wire to get at and remeasured and got 12+ amperes. I reasoned that I had reduced the current roughly a 1/3 so all 3 must be drawing current when all were connected. Sounded good to me. It starts good anyhow, but I feel better knowing. Hey, summer is coming.
