Next check was to use the 30-0-30 ameter and check directly to the rear glow plug from the positive battery terminal. This was a direct short and I was arc welding with 12 gauge wire....
You have to pull the glow plug connector from the relay before you try this. They're all in parallel (except #1) inside the relay, so you were testing five glow plugs' current, not one. Unplugged they're isolated, and thus individually testable. You can also jam the 12-gauge romex into each connector socket individually, and flick the other end to the battery.
So, my next thoughts are to check each individual glow plug with the ohm meter (which I need to buy since the HF one I have is not working) and see if there are dead shorts in the system. Could the relay be the cause of this mess?
Certainly. Rare, but possible. When buying a meter, consider a real one such as a Fluke 80 series. They've been making them for years now, they're about the best thing out there. You can generally trust what they say. -- Jim _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
