I also have tested the wiring that leads to the switch.  Connected the
tester to see continuity and there is none, while the key is not on.
Then I tested on an other van, and that did have continuity.
I'm not sure which is good.

TTS sense air temp below the plenum to have the cold start valve function on
start-up for more fuel when the engine ic cold...I've seen many more cold
start valves fail than the TTS...I would pull the csv and check the spray
and pattern into a clear jar first...

Hi to all,

It is an old air-cooled engine.  Has starting trouble cold.
I am to test the Thermo time switch.  I can’t find instruction in the
 “Bible”, only to test the wire that leads to it.
That test says; your test light will light up when you turn on the starter.
Fine.
I only checked continuity there and it has.

Now, I just don’t know what it the best way to check the switch while it’s
in the car.  As You all know, it is under the air distribution box and other
wires and the fuel lines are all in the way.  Only with a long pair of
pliers can I get the plug on or off.
I imagine, the switch is to make contact and no-contact to close a circuit.

Question; what should the position be while it’s cold.  Continuity or not.

Best wishes to all,
Zoltan
