Listers,
Thanks to everyone who replied on the radio and spark plug question,
I got a wealth of education on the subject. I ordered a set of resistance
wires from AutoZone and will stop up to Radio Shack to pick up some of the
suggested capacitors.
As I rummage through my old TR4 memory... I seem to recall those noise
suppressors being on my original car.
Thanks again.... this list is a treasure... and fun to boot

>>Hi Brian,
>>
>>Probably the po installed stranded copper ignition wires rather than
>>resistance wires. The tradeoffs are: copper wires will last for many
>>years, and probably will give you a hotter spark. But -- they will allow
>>your ignition to not only interfere with your radio, but also to radios
in
>>cars near you as well. Resistance wires will suppress radio
interference,
>>but my experience has been that they will only last 2 or 3 years and then
>>have to be replaced. I used to buy them from the "big 3" but now I just
>get
>>them from Auto Zone and cut them to size myself.
>>
>>Replacing the wires will solve your problem, and it's not a bad solution.
>>When doing it, don't forget the coil-to-distributor wire.
>>
>>Also, make sure the radio case is well grounded.

>>Hi Gang,
>>
>>I am so glad to be asking these questions instead of the " where does my
>>camshaft go" questions.
>>
>>I installed a new radio in the TR4. One of those 70's retro ones from
>>Kenwood. The reception and sound is perfect with engine not running.
>>Some noises start coming at idle but when the engine is revved to normal
>>level the radio signal is overcome by ignition noise.
>>
>>I have changed to negative ground. And the ignition wires are as they
>were
>>when I bought the car last year... but they show no sign of wear.... and
>>they look very period with orange-red rubber boots on the plugs.
>>
>>I am using the NGK BP6ES plugs which I am guessing are not resistor type
>>plugs. What do I have to do to get the noise out.
>>
>>I remember this battle has an original TR4 owner.
