I replaced the overvoltage relay and it seems to have fixed the high rpm.
Thanks for the advice! The SRS light is still illuminated. Is there a reset
button or is something else wrong that I should address?

Sadly, B. My 560SL had that light lit, and ultimately it turned
out to be bad
That I dont know, its possible it also has some problem with the SRS
although I have not had to diagnose that myself before.

The SRS light is on. Is there a way to test the overvoltage relay? or idle
computer or actuator?
does the SRS light come on at the same time? If so, its the overvoltage
relay. If not, probably the idle computer or actuator.

If the SRS light is on, then its the overvoltage relay. Its going to be
the relay with the little flip up door and the fuse on top of it (red)
between the 2 firewalls. Check the fuse, otherwise replace the relay.

You just did. Nothing taking power from the overvoltage
relay is working right.
Replace its fuse, and at least try re-seating the relay.
That alone may do it.
These older OVP relays are pretty
Oh yeah, one other thing. Try not to drive the car in stop and go
traffic until you get this fixed as the stress on the tranny will
cause high heat and ultimate failure. Big bucks.

My son has an '87 420 SEL and once started, RPM's reach 2000 at idle within
4 seconds. The linkage isn't bound and does not appear to have even moved
once started. Where should I begin?

Idle control valve -- about have the size of a coke can, connected to
the air meter horn boot at the rear of the manifold (bottom half,
it's sorta buried).
Make sure it's connected and the hoses are intact.
You should also pull the codes from the computer to see what if any
