Ferrari Mailing List: By Jove, I Think I've Got It OR "The warm start gets a cold start"

[Paul Bennett (pbennett]

Following up on Michel Savard's  solution or replacing the Thermo-Time Switch
This part is rearward of the thermostat at passenger side engine valley.

Today's Test Procedure:
Warm engine until radiator fans are on.
Remove electrical connections to TT switch in question.
Car starts immediately without playing footsie w/gas pedal.
Replace electrical connections.
Car won't start without extensive pedal play
Remove electrical connection.
Car starts immediatly  

That's good enough for me so I'm on a quest for a parts quote.  

What and Why of the Thermo-Time Switch:
The TT switch contains both thermostatic contacts (terminal W to ground) AND a 
bimetalic switch heater (terminal G to ground).  Contacts open after 12 seconds 
OR if coolant warms above 95F.  If TT Switch contacts stays closed when engine 
is hot, the cold start injector floods the engine.  Flooring the throttle 
usually clears the excessive fuel.  If the contacts never close, the cold start 
injector will not function.

Tomorrow I will determine if the part is actually bad or if the wires to the 
terminals have simply been reversed.  My TT Switch does not contain the same 
type irreversible snap-on type connector as does 4 other 2 terminal devices 
nearby but instead has two independant push on connectors.  If clean living 
provides my solution at simply reversing connections, I will only be out the 
$90 for the fuel pressure tester.
