Hi all, has a few issues so dug further into my wiper unit. Motor (with pump and pulse) with correct pulse switch)
Upon cleaning I noticed the little black transistor on the PCB had a broken leg. Found direct replacement and soldered in. Capacitor tested ok.
In the main body there is what looks like a large wattage wire wound resistor, this had a broken centre bar, but full continuity, i used a bit of hot melt glue to set the bar, and it shows 3.8 ohms (it's stamped with a 20?)
So installed and all functions worked except pulse (has one ever worked lol)
Capacitor voltage is rising and falling.
Went through tests in manual and it pointed to timing board. Thought I would disassemble and clean as contacts could be causing problems.
Took photos, but unfortunately not good enough. There are a few pics in the manual, clear enough to see the top 5 or so components, but not below.
Can anyone tell me what order they should be in the "stack".
I have trial assembled as per below, pretty confident the top is OK, just further down is an unknown.
The long copper holding switch contact does seem a little low.

From top to bottom I have.

Holding screw
Top plate with angle leg then wire that goes to capacitor
Insulator
Tab for Terminal #6
Insulator
Override breaker arm (copper)
PC board (has metal strip on top)
Green wire tab (has contact pad for override breaker facing up)
Tab to resistor (terminal 7)
Holding switch contact arm (long copper)
Black plastic spacer
Tall white plastic stand with 2x pins at top
Base tab for pulse relay
Housing

Pretty sure the bottom 5 or 6 are in the wrong order.

Ant takers 😁

pics are of my mock up,

Cheers

Just found this on line, might be in business 😂

Ok, reassemble as per pic, all functions except pulse. Grrrrrrrrrr
Tried the pull #6 terminal in the trouble shooting guide, still runs continuously, then pulled yellow from pulse relay and wiper stops, points to timing device assembly.
Have tested components in this and they seem fine?.
Any pointers?

OK, need an electronics guru LOL . I am way out of my depth !!!

Tested the old transistor (had a broken leg) against the new replacement (same part number) and the results differ ??

See diagram for E, C, B locations. Factory one had it written on it, replacement was from the manual (Fairchild semi conductor)

So I probed the pins as per test instructions and only get outputs on one leg ?
See table below for results.

It looks like the polarity of the transistor (part number 2n5306) is reversed ???
Supposed to be NPN, but in the case on both the Base is listed as the RH leg, not the centre ?

Is it just a simple case of swapping the location of the legs on the board ?

I can post a diagram of the board if that helps

Anyone? 🙁
