I'm working on my starting problems. I pulled out the Overload Voltage Relay and tested it. I used instructions from a search of this site.....set the multimeter to diode mode. Positive test probe to terminal 31 and neg to term 30...... I got a reading of 0.544 V. I understand the norminal value is 0.4V to 1.5V. Since my OVP read to close to the lower end of the nominal value, could this still be why my w126 is having such a hard time starting?????
As I quick recap: The car has a hard time starting whether it is warm or cold out. I have to pump the gas pedal before it finally starts. If I shut it off and restart, it starts right up. Also the idle will drop when I stop at a light etc. The car sort of bounces up and down.
I did look at the fuse in the OVP, the filament looks intact.
