Reply to "Intermittent wipers for Pre-L Panteras"

This thread was lifted to an incredible academic level that was in fact of no (technical) help to anyone searching for an easy way to incorporate an intermittent Wiper option!

As I wrote previously the "Smartscreen box" did not work well on my Car, but that does not mean it will not work on other Panteras. My Car has modified wiring in several areas and that might be the reason. The "Smartscreen box" has helped a lot of Car owner with a 100% identical Wiper system to the Pantera. It is a very common Lucas setup which is on millions of British (and others) Cars.

The operation of the unit is straight forward.

Pressing the intermittent window wash switch activates the wipers on normal speed for three cycles and park correctly.
The existing two-speed wiper switch works completely as normal.
The stock switch and wiper motor do not have to be changed.
No additional wire is required in the wiper loom if there is sufficient slack. A short portion of wire may be required from the wash motor power wire to the unit.
No additional fuses are required. All wires (except the wash power wire) are located in the wiper loom.
The intermittent feature has an adjustable delay range of 3 to 30 seconds.
The intermittent delay is easily set. Turn the wipers on to low speed for one cycle by flicking the wiper switch on & off rapidly. Wait the delay period you want, and flick the switch again. The delay is now set, and the wipers work intermittently with the wiper switch left in the off position. The delay is canceled with either one more flick of the switch, turning the car off, or turning the wipers on continuously.
