Location of ovp relay 1992 500sl
 

Need help--1992 500sl no ignition. I understand ovp relay could cause the problem. Where is the relay located? Is there a place I can check for voltage to the EZL? Is there a check for the crank position sensor? Any help greatly appreciated.

The OVPR is under the plastic cover at the rt/rear of the engine area. However it doesn't supply the ignition module w/power, that comes directly from the ignition switch.
The crank sensor wire plugs into the ignition module.
