I have a 1991 300E, with 156K miles that i am trying to sell. I am having intermittent stalling issues of which i have replaced some parts. I ordered an OVP protector online, but received a part which i have not clue what it is, or what the OVP looks like.
I read here that it has a fuse on it, and i do see a part with a red 10 A fuse on it.. is that it? is that what needs to be replaced? the part i received looks nothing like that and cost me 90 bucks. i d0nt even know what part i got. I emailed the seller, but he hasnt called me or emailed me and its been a coupla weeks. he does have a big parts site, but im not sure what part is what, im new to the benz.. any help would be appreciated...JIM

HI Jimmy

The OVP relay is behind the battery, there might be a black cover keeping you from seeing it. Yes it does have a fuse(s) in the top of it. Early ones were 10 amp (red) later one might have two 15 amp (blue) fuse(s). Had to tell what part you got since you didn't provide us with the part number of the part you got. However it is not an OVP relay if it doesn't have a fuse in it. Good luck on getting your money back. Try getting your parts from here at Fast Lane. The part number I come with here is P2056-18126 which is a Fast Lane part number not an MB one.
