[Healeys] 100 Heaters

[robertduquette at sympatico.ca]

I got to spend a few more minutes on this last night.  I do have most of that
second valve.  Is there supposed to be a knob on the side with the spring?  If
so, are they obtainable?  It's not apparent to me which way this should be
turned to get the coolant to flow, but I imagine that should be easy enough to
figure out with the car running, if I weren't afraid to touch it again.  I
touched the place where I expect the knob should be and prestone leaked out
fairly quickly ... on to the car below.  :(  Is it supposed to open/leak that
easily?

There is a line drawing in the service manual that makes it look like there
should be a knob.


I felt around behind the heater and found that both heater wires aren't
connected to anything.  There appears to be a male bullet and a female.  The
male is painted red, so I assume that it hasn't been plugged into anything
since at least 1986.  I did not feel anything that the wires should attach
to.



The dangling green wire is in a small group of 3 wires coming off the bigger
harness and one of the 3 wires is attached to the back of the OD switch.  Does
anyone know if this is the heater motor green wire?  Can anyone tell me where
the other wire connects to?



TIA

What I found was 2 black wires exiting the heater case and a green wire with
the end taped up hanging down behind the dash.  I jumped to a conclusion and
went in the house to check for schematics and found one where it showed a
green and a black wire.  So, I assumed ( incorrectly, it seems ) that that was
the green wire.  I couldn't see the back of the black pair of wires but felt
back trying to see where they went.  At that point I had seen the green wire
and was looking to find where it should connect to ( though it was obviously
too short ).

I also later found reference to a second valve that should have been opened,
near the water pump, but the car was up on the hoist at that point in the
evening and it remains a mystery to me.  I'll check later.

I should have enough info now to track this down.

It was certainly a fun drive though!!
