[TR] TR4 question

[John Macartney]

Jiminy, this is testing the product knowledge going back that far!!!!!!! 
AFAIR, the TR4 had single speed wipers with two speed as a chargeable option and factory fit for all
markets.
The 4A had two speed wipers as standard for all markets except North America - with a two speed as a
factory option. Then, I *think* two speeds were standard fit on all N.A. models from early 1966
onwards. If anyone has a copy of the copious (and different) 150 export market build sheets, I might
be able to be a little more accurate. What does Saint Piggot have to say on the matter?

That's a good question! My 4A has a two speed motor. I do not know when they switched from single
speed to two speed.

I guess the answer could be "check your wiring" and "how does your switch work".

If you have the switch, does it have a single pull detent or two detents in the pull?

For the wiring, there is an extra wire going to the motor that activates the slower speed. I am not
sure exactly how it works to make it go slower! So if you have wiring that looks similar to the 4A
wiring diagram, rather than the TR3 wiring diagram, then it probably is a two speed system that it
is set up for.

Sorry I can't be morehopeful. I have a feeling that somewhere in the TR4 range, they switched over
to a two speed system!
