Did today's posted results give a clearer picture of shat the issue might be?

I specifically said voltage between the control terminal and the _positive_ battery post. With an open coil and a working switch the voltage between battery "+" and the solenoid terminal: * switch off (at rest) it will be variable and flaky (depending on the impedance of the meter, the insulation of the test leads, how the leads are held, etc) * switch on (cranking) 0 volts - because there will be zero current flow. If the coil is good and the switch is good: * switch off (at rest) it will be 12.8 V - because at the current draw of the meter the coil of the solenoid makes the trigger terminal appear to be ground. * switch on (cranking) it should be less than a volt, or so - because the there is some resistance in the wire so there will be a bit of voltage drop due to the current flow. And so on. If you don't understand the theory, just post the results of the test and we'll interperet for you. Just be sure to follow the connection instructions! -- Philip _______________________________________ 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 _______________________________________ 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
