I do have that. 0.26 - 0.3 V for the good starters, 1.5 V for the shorted one when hot and not working. This is also with the glow plug relay control cable disconnected so no supply voltage droop because of glow plugs. But that is only valid on this car - because I'm pretty sure the positive cable has been upgraded. I know the negative has. I guess I should share all the numbers anyway, "B+" is the clamp on the positive terminal on the battery. "B-" is the clamp on the negative terminal on the battery. "M+" is the copper braid wire between the solenoid to the motor itself. "M-" is a threaded hole on the back of the starter motor. "C" is the body end of the negative battery cable "S+" is the input terminal on the solenoid On the old started when it worked and the on the "new" starter. 12.6 B+ to B- 0.15 B+ to S+ 0.18 S+ to M+ 0.33 B+ to M+ 10.4 M+ to M- 0.255 M- to B- 0.062 C to B- -- Philip _______________________________________ 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
