Not really. Or sort of. You can use jumper cables to connect it to a battery and see if the solenoid kicks the bendix drive out and if the motor spins. (hold it tight while you do this, it jumps a bit as it fires up. I usually stand on it on the ground) But I know of no way to test if it's going to require thumping the solenoid to get the car started, or if it's worn enough it drags when hot, or if the bendix will always engage. And I tried. Again and again. In the last year or so, I've monkeyed with parts an pieces from about 5 starter trying to get a dependable working on. And none of the out-of-the-car testing I could device was of any real value beyond determining it spins, the solenoid operates, and there isn't a field winding shorted to the case (very easy to do) I got really good at changing the starter on a OM616... _______________________________________ http://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
