FWIW, Just took a look under the dash on an A/C car.  The heater valve is

between the top pipe of the heater core and the top pipe going into the

engine compartment.  I agree with filling from the bottom to help purge air.

But it seems like you would stop the flow of hot coolant before it goes into

core, not on the way out.

won't purge itself of air. Unless the pipes cross over and the upper port in

fact connects to the bottom.

whan I bought the car in 1999.

If you do, which of the following do you have:

(1) a throttle plate stop screw (allen head) fitted

or (2) a different kind of screw with nuts

or (3) did you fit one yourself?



There's a photo of what I'm asking about on the FB page which I think ANYONE

can view:

This is one of those weird little detail things I want to chase down.

Which heater hose is the 'hot feed' from the engine to the heater core under

the dash?

- top or bottom hose as they go through the bulkhead from engine compartment?

I plan to install an in-line heater shutoff valve to prevent (some) heat

leaking into my TR7; the existing heater control valves don't fully close the

water supply to the heater core



Planning for our drive to the 2017 Triumphest in Flagstaff, AZ; a long way

across the Mohave desert from the San Francisco Bay Area.

In a black car with black interior (TR7 Spider) and no AC....

Thanks!!

I would start with the main light switch. Do the parking lights come on? If

yes, the next thing to check would be the dimmer rheostat.

I went to a Brewers game last night and got caught in an enormous rain

storm.  The kind that cars pull over.  Anyway, after the game was over I

turned the car on and found I had no interior dash lighting.  Thus I drove

home not really knowing how fast I was driving.  I have replaced a couple

fuses that I felt may be suspect but to no avail.  So, still without

interior lights.  Can anyone give me an idea what may be the issue?

thanks

I ran some tests today from suggestions from the list.  1) Jumped the oil

pressure switch, No change.  2) Direct wire from battery to coil bypassing

ign switch, no change.  3)  Did a test on the Lumenition module, nice

spark.  4)  Dug out the old dist. cap and wire to change,  but decided to

change only one wire before changing all.  The Coil wire.  Car started and

ran for 10 minutes and temp reached 210 degrees when fans kicked in.

Before the engine would quit at 130 to 140 degrees.



That was a new Mallory wire.  I will continue to watch it (fingers crossed)

and if it acts up again I guess its a new distributor or electronic

ignition kit.
