CD Elec Schematic Unreadalbe Help - PeachParts Mercedes-Benz Forum

Though I usually have good luck using my MB 124 Service Manual Library CDs this time is an exception. Trying to find the problem with my non functioning rear wiper/washer ('87 300TD). Both screen viewing and printout of page 161 are too "washed" to view enough of the details.

Relay clicks when either rocker switch is activated. Where are the terminal and connection points other than at the relay? Is there an extremely descriptive thread that I have missed?
Thanks

Let me correct the subject . . . Unreadable not unreadalbe. I guess if that is all I get wrong today I'll have a super day!

Did you use the zoom?

What page on the CD?

Yes. I used the zoom on page 161.

I have been tracing the wires/power and just came in. Using the interval and regular switches I have power going to two pin receivers at the plug leading to the wiper motor. Relay is clicking away as it should when I activate either of the switches as well as the washer switch. I have not made it to the motor yet. Do you happen to know which pins on the final five wire plug should have power and when? As I look at the plug and its receiver, five of the six have pins. Three on one side two on the other. I get 12v at the two end pins [ .:: ] those on the right in my preceeding diagram using period and colon marks.
Thanks for your time.
