It is the panel light dimmer control.  It is there next to the AC switch.

Guys, your amazing!  I cranked on the rheostat button several times and

sure enough it began to light up again.  Thank you so much for all your

expertise on this and everything else.

thanks again.

The one below the heater controls, with the double headed back and white

arrow.

Dave, can you assist with telling me where this rheostat is? I have looked

all over. Basic instructions are always helpful.

thanks

Center of the console. It is used to increase or decrease the inside light

intensity. Below the radio, beside the lighter.

Hi Jim,

Glad to hear that you enjoyed the TR8 Day at Gaydon in the UK. It was greatly

appreciated all the help you gave us. I think we have a very interesting range

of TR8's over here. Final total 38 cars - not bad!

You have pictures of my car KHP533V and Keith Cox's brown FHC which show the

throttle stop screw. On both cars there is adjustment via a machine screw and

lock nut. Remember that Keith's car has an experimental EFI engine and mine is

the first production EFI/Auto.

Some years ago I built up a spare EFI plenum from spares bought from Unipart.

The throttle lever was not drilled, so my feeling is that it wasn't meant to

be drilled except where necessary . Perhaps Albert can shed some more light on

the subject.

Best regards

Rex

No big deal.  Once you start the engine and get some rev's the pump pressure will purge the heater pretty quickly.

It really doesn't make a big difference.  If you shut off flow out of the matrix there will be no flow into the matrix.  The only advantage is that the static pressure in the matrix will be that of the open hose and if the valve is in the supply hose the pressure will be at the pump return pressure which is lower.  But if the heater isn't leaking now it won't leak with the valve in the return line closed.



BTW, we drove that route in 2009 on the way to Triumphest in San Luis Obispo.  No issues.  Great scenery.  Watch out for the donkeys in Oatman.

Wayne & Bill,

Thanks for your fast replies.

Of course I was hoping for the opposite as getting to that lower hose

is more difficult....



This drive is going to be a bit like one of those desert/altitude soak

tests they did on the cars during type testing.

Only now the car is 37 years old...



900 miles from the SF Bay Area to Flagstaff

- through the sierra nevada (Highway 88 - summit 8,570 feet)

- down Highway 395 (east side of the sierra, more high elevations inc.

Conway summit 8,163 ft)

- across the desert north of Death Valley - Montgomery Pass 7,150 ft)

  (along CA Highway 6 - the last CA part of the original

transcontinental Highway 6)

- south to Las Vegas

- southeast to Flagstaff (via Hoover dam)

Temperatures up to 85F on the east side of the sierra, 95F in Vegas

We are going to cook....

Driving at night sounds better, but the group is planning to drive

through the day....

My TR8 has a screw with lock nut. Sorry, I can't tell if it is Phillips or

allen head. I'm betting it's Phillips.



An answer to your quest may be found in the Rover 3500 NAS parts book. The

Stop Lever (ERC3571) is detailed. There is no associated Stop or Locknut in

the diagram or parts listing.

Hopefully someone has access to a TR8 EFI fiche and reader and can check to

see if the listing is the same. I have both, but they are hiding in the depths

of my attic.



My WAG is that due to anti tampering regulations, the idle stop wasn't fitted

to either the NAS TR8 or SD1 by the factory, which is why it's not showing in

the SD1 parts book.



Once the cars got stateside and dealers had to keep them running, my bet is

that many of the cars got fitted with stop screws to increase idle speed to

prevent the engine dying when the AC was under load.



The dealers were pretty canny and did a lot of mods to make the cars shift off

the showroom and keep customers happy.



A friend of mine claims he sold a lot of TR7s by changing out the factory

throttle cam for one with a more aggressive profile.
