One major complaint of diesels of the time was the long pre-glow needed to start a cold engine. GM decided to "solve the problem" by applying 12 volts to 1.5 volt pencil type glow plugs, thereby instantly heating them to white hot. The system worked very well but as I stated, when the timer failed it always failed with glow plugs on.

Why not just wire them in series then? -- Jim _______________________________________ 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 No virus found in this incoming message.
