Anyone know where to find the overloard relay on an 83 300SD?

Thank you in advance

Rick

It's not an overloard relay, it's an overvoltage protection relay. It's function is the blow the fuse(s) on top if the supply voltage exceeds 22 volts thereby protecting the ABS and ECU computers.

It's located between the two firewalls and has either one or two fuses on top.

Thank you kindly for your response....I will take a look in the morning. Is it between the fire walls over by the battery?

In the 300SD, it's in the fuse box: rear, second row from back, towards the cars midline. Red/orange fuse holder, red fuse (should be red at least, 10A). Can't miss it.

1984 300SD (bought new, sold it in 1988, bought it back 13 yrs. later)

I looked and looked and looked and can't find it.

I didn't see it in the fuse box....5 ice cube relays....2 black box relays.

I looked between the two fire walls and didn't see it.

I even looked under the driver and passenger kick panel and nothing.

Anyone have any clues?

The car was in bad shape when I got it and I am curious if perhaps one of the "ice cube" relays in the fuse box shouldn't be there. Anyone have a diagram or a picture that would help me out?

Its an 83 300SD.

i don't believe the 1983 300SD has an ov relay. the 83 i had didn't

Thank you guys..........I rechecked again just to be sure and I am confident the bigger...better overload protection relay is NOT present on my car. I even vacuumed out the firewall just to be sure the relay wasn't hiding!
