Per,
Thanks for this. Just in case we all start chasing a red herring:- it?s not
overheating; the radiator is up to a correct level and stays there. No boiling,
all well on the temperature front.
No water coming out of heater box.
I?m thinking it?s more electrics than heat related.

When you switch on the ignition you feed the brake switch with current.
Normally this switch is located somewhere under the dynamo.
What was the smoke coming from? Well, the heater box is located under the dash.
Could be leaking.
You say the engine didn't get hot.
It might be that it actually got very hot because the coolant had leaked out.
If the level of the coolant is very low, e.g. under the sensor you will not see
how hot it is on the instruments. The sensor is located in the cylinder head,
just under the thermostat. The engine will boil though, did it do that?

I have received 2 emails from my nephew.
He has an early Phase 2 BJ8 ie with the single light setup front and rear and
the 8-way flasher relay box. Car is LHDrive.
The car?s wiring loom looks to be new and in excellent condition; it looks like
it has been competently installed with all clips and grommets where one would
hope to find them. The individual wires are emphatically not old & crumbly ie
flakey insulation.
The car starts and runs well. It feels strong and is well behaved ie it coped
with appalling traffic on a very hot day when we drove it out to Chantilly. It
started first time when the engine was hot. In fact, the engine didn?t get hot;
I reckon it has a recored(?) radiator. Certainly it has the 6-blade fan
offered, I think, by the factory (like a 6 blade version of the normal 4.
Something we don?t usually see or need in the UK).
First email:- ?It was very hot today and something weird happened: a bit of
smoke came out from just above my knees (just below the dashboard along the
steering wheel pole). the smoke was white and little (about as much as a match
would make when it goes off, but white). Then a funny noise went on for 5
seconds (like a motor, a bit like the starter motor we can hear at the end when
the engine doesn't want to start (do you see what I mean?).
Anyway after that incident everything went back to normal:
-all the lights (turning indicators, panel lights, all the instruments...) seem
to work.
I have no idea what happened and I have not found anything not working!?
A few days later, the second email:- ?Everything electrically seems to work.
Except that when I push on the brake pedal nothing lights up at the back.
Shouldn't it??
This is the Paris car, my being back in the UK with the previous issues cured.
Now:-
I am presuming that the two issues are related?.the smoke and the lack of brake
lights.
I am discounting the heat reference.
I am puzzled by there being no brakes related wiring under the dash yet that?s
where the smoke came from.
The ?funny noise? has me stumped.
The only place where braking circuitry and lighting circuitry meets is in the
8-way flasher box. (Barring bare wires shorting out).
I am going over to Paris in about a month?s time in order to help get the car
down to Roscoff and thence by ferry over to Plymouth in the UK and up to my
house. I will then have it for a few weeks and will do various things to
it??seatbelts being item one.
So, I (we) would like to make the longish journey with brake lights and without
smoke.
I have, I think, all the tools I need in Paris but I would welcome ideas??..
Has anyone had this happen to their car?
What is the likely connection between the two seemingly irreconcilables. (Smoke
under the dash yet brake lights only are affected).
Can anything to do with the brake light switch lead to smoke under the dash? I
can?t see how, myself.
I just want to be slightly prepared when I get there. I won?t have much
time?..certainly not enough to get replacement parts over to Paris from the UK.
Any thoughts?
Thanks,
Simon
