Err.... I'm trying very hard not to be, but I am now completely confused! But if we're saying the same thing to Andrew then I'm happy.

The thin wires are identical between 3 & 2 speed control boxes so they remain compatible with ECU outputs.

Follow these 2 Pics from Keith's original thread.

The thick brown PLUS 12V goes straight to Motor Red.
The Grey from the middle relay feeds the resistor (giving LOW speed)
The Red (switched NEG!) wire from large relay goes to other side of resistor, where there is also a joint to the Motor NEG.
The Large relay simply "shorts" out the resistor giving FULL speed




Just the output (thick wires) differ in the later control boxes.
Also note the end small relay is connected electronically but the output is unused.

Thanks to all of you guys! You really helped me with this stuff!

So, I checked for earthing coils and guess what I've found? One of relays was dead (well, not dead, just corrosion on contacts), so I cleared contacts with vodka and now everything working fine with my old 3-speed motor.
Also, I made a new 2-speed motor using Russian analog of relays, so it runs fine too. I will keep it for future!

Thanks again, if you ever be in Moscow feel free to contact me!

Well done Andrew. Thanks for letting us know.

Good result Andrew.
Like the Vodka bit, must change the bottle of Cellulose thinners in the workshop for some Russian magic Juice
