Thanks, I'll take a look for the sender.
I don't know about the speedo -- if electronic would it have a fuse?
Maybe that is affecting the temp gauge too? The tach works and the gas
gauge appears to work as well, at least it is showing 1/2 tank.

Temp sender should be on top of the engine, probably around the thermostat. I
don't recall where they are on a M117(?) but that’s a pretty common place for
most of their gassers.
Someone correct me if I’m wrong, but the later W126 chassis cars had electronic
speedos, I thought.
The “mold” which it certainly could be, if white, is a common issue with
clusters of that vintage. Moisture causes the surface of the plastic to break
down and you get the white spotty appearance. I don’t believe there’s a fix.

I got the new caliper and front pads on the 560SEC last evening and drove it a
bit to bed them in, all was well once I poured in some tranny fluid but I
noticed the temp gauge was inop and the speedo too. I was degreasing the engine
a bit and might have knocked a wire loose or something.
Anyone know offhand where the sender is on the engine? I’m too lazy to dig
into the CD to look it up.
I should take a look at the speedo cable too I guess. And the instrument
cluster looks all moldy inside, I guess I should pull it and clean it sometime.
I think I’m going to borrow a buddy’s powerwasher and blast it underneath and
whatever I can get on the engine that won’t mess up the ignition bits and
whatever other electrical stuff. It’s pretty grungy. I should be able to see
various leaks then and tend to them.
The car is entertaining, certainly nothing particularly car show quality.
