Don: I really think your time and energy would be better served by trouble shooting the existing system.
BTW, Marshall would admonish you for not telling us the car. :-) I am guessing a late 123? > I *think* the plugs are working, because last year I had a voltmeter hooked > up and I could see the load when the plugs are on. A voltmeter is inadequate to test glow plugs. An ohmmeter will give you some indication, but the ultimate test is a dc current meter in series with the individual plugs and connected to the battery. I use an old dash type current meter, as you need it to read up to about 25 amps. When your problem occurs it is not clear if the car starts ok or is the flaky light bothering you? On both of the relays did you thoroughly check or replace the fuse? -- SANTÉ Doug Quance Consciousness: That annoying time between naps. 90% of being smart is knowing what you're dumb at. _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
