OVP preventive maintenance?
It seems that the OVP is one of the first items that is suspected for many problems posted.
My 190e will soon be celebrating her 10th birthday. I have already replaced all fuses in the fuse box. Do you recommend that I replace this relay as preventive maintenance? Is it located behind the plastic wall by the battery on a '93? My thanks for any advice.

OVP repair
Mbdad,
I had an unusual hesitation, then a complete stall, on my '85 500SEC. In checking all my fuses, I opened the clear top on the OVP. To my amazement, the fuse fell out into my hand!! I pulled the whole thing out and took the red top off. I found that the THIN aluminum contacts for the fuse had loosened. I took a fine pair of needle nose pliers and GENTLY squeezed the contacts together. I replaced the fuse and it has not faltered since. I think that the weight of the plastic end of the fuse was working as a lever arm against the contacts and forced them open over time(vibrations). Anyway, it took longer to find the problem, than fix it!! Good luck, John F.
