87 300SDL OVP Problem Help

So I still am having a problem with the fuse blowing in the ovp relay. I tried replacing the ABS sensors. I also tried replacing the Klima relay, the ABS computer, and also the actual OVP relay. Now, I am assuming that I have a bad ground maybe or a short somewhere. Where should I start to look or what else can I do before taking it to the dealer to diagnose it?

Try this link. Check the alternator circuit voltage or remove the cable from unit and run the car for a while. Hope this help.

question is does the exhaust system have anything to do with the OVP relay protection fuse. Have had problems with the fuse for about 6 months now, and last weekend i replaced the flex pipe since it was leaking and becoming really loud. Today I wanted to play with the OVP some more, so i stuck a new fuse into it and drove the car for 30 min and could not get it to pop. Does the computer monitor the exhaust fumes in some way, because a couple weeks ago i played with the ovp and it would blow after 2 or 3 seconds after the car starts to drive. NOw today after the new flex pipe i cant get it to pop. I tried to accelerate really hard, rev it really hard, brake really hard in the rain, and cant get it to pop. Now Could this be connected somehow or is this just coincidence that the relay fuse wont pop today?
