The battery died in my '86 560SEC after the car sat for a week. The battery
is new. Charged it up,started the car and verified that the alternator was
charging. Looking into the fusebox under the hood, I noticed that a relay
was hot to the touch. There are 6 relays in the drivers side of the box. The
hot one is the last one toward the front of the car.
Does anyone have a wiring diagram that shows the function of that relay?
More info on relay:
The relay is for the seat adjustment motors. Seats will not move with relay
out. Part #0015420219. On the otherside SR9850.
I disconnected the Neg. battery cable with the relay in place and checked
the current draw with a heavy duty ammeter.Saw 3 amps for about a second
then faded to nothing. Checked it again and again.with the same result.
Seems to draw about 50 milli-amps after fading, although I blew the .5 amp
fuse in the little meter checking.
At this point, the relay is getting warm again with the car just sitting.
I wonder if it is a bad relay?
