I have just wired in a Wiper Delat relay to my wiper circuit.

Im using Mark 2 Astra Switch gear & relay and Lucas wiper box.

Thing is when i ran it during test, using a test light, i managed intermitent wipe cycle, but when its connected to the motor it does on intermittent wipe and then the relay is rapidly clicking but does not operate motor.

Do i have to install anything else in the wiring to over come this.

Also which ever speed is fed, the motor only funs at the same speed.

I think it is covered in this forum, there's wiring diagrams too
