I'm getting a serious case of 'burn the damm thing to the ground' right about now. This is the deal so far.
Last night I got the fans running, the right fan had a brush hung up in it's holder.
Fans now cycle according to a/c demand.
Next, download PDF file of sensor wiring diagram.
Notice an anomally...the Brown/Yellow on the car goes to the WASHER sensor and the Brown/Blue goes to the LOW COOLANT sensor. On the diagram it is in the reverse ( ???????? )
So I remove headlamp and try to move wires to diagram spec'.
However they do not really want to go that way and I had to cut the loom sleeve back for enough slack to get the plug(s) to reach the new positions.
Switch on, lamp on. Fire her up, lamp still on !
Short across plugs ( both ) still on. Short across one after the other, still on.
Ground out the Brown wire, still on.
No shorts or sensors in at all, still on.
Checked with test lamp by shorting sensor Brown/Blue to ground,
LAMP GOES OUT AFTER 20 SECONDS !
Turn off motor, put all back as factory, lamp on !
Go back to test lamp in Brown/Blue, lamp still on, not off as before.
Put sensor on bench, use magnet by the sensor probe, DOM reads 'open' and 'closed' as I move the magnet up and down the probe.
Return all to factory, lamp on.
Run ground from Coolant sensor Brown wire, lamp on.
I lost my last post update just now.......
I checked ohms across Washer : 0.00 ohms and 173.8 ohms.
The Coolant sensor with magnet = 005.1 ohms
" " " without = ........ OL. ........ (open.)
I'm begining to wonder ....have MB sent me the wrong sensors ?
If the post by Mike is correct, there should be series resistence.
Washer sensor # A 210-540-00-45.
Coolant sensor # A 129-545-02-24.
This is burning me up !
Is the PDF file correct ? I noticed the 'ru' in the address, this is for Russian dot coms/orgs/gov etc....The file seems to be from MOD though.
