Hi Wil,
Electrical:
I think you tapped the 12V hot from the wrong circuit - i.e. the circuit
which is in use for the dials - gauges. It derives from a voltage regulator
which shows this kind of outlet characteristic. The reason for this is, that
the gauges should indicate the same value at the lowest rev as well as high
revs, but the dynamo - alternator produces a much higher voltage when
operating at high revs. Try to hook the radio to the circuits like cigarette
lighter.
Clutch:
As the clutch is quite new, some mechanical move at the clutch itself or its
operating arm at the clutch slave cylinder might have moved a bit.
Better to check if all still fits well as it should.
Cheers,
Hans
'71 BGT

Subject: Two unrelated issues... 1 electrical, 1 clutch
Hi all.
Wondering if I can tap the untold wealth of MG knowledge out there again to
get over a couple of more humps here...
The auto: 1969 MGB Roadster.
First issue is electrical. I have installed a stereo where my old am radio
used to be, I used my trusty voltmeter to find a good ground wire and a good
hot wire (12V). Now that the stereo is installed, it starts up normally, but
then quickly (3 seconds) So I stick my voltmeter in there with the stereo
and find out that what is happening and see that the voltage starts out at
12V, diminishes to 9 1/2 (at which point the stereo turns off,) after the
stereo has been off for a second or so, it goes back up to 12V, the stereo
comes on and the cycle continues... This doesn't seem to be affected by the
RPM of the engine (or in fact if it is running or not...). I have been
having this problem for a few days now, but because me alternator light was
on, I just figured that is what it was, I have now replaced the alternator,
no more warning light, but still the same behavior with the voltage swing...
Any suggestions?
Second issue is clutch related. It happened today while I was driving home
from work, I was driving normally in traffic, when all of the sudden during
a shift from second to third the behavior of the clutch pedal changed
dramatically. I used to have quick a bit of range in the clutch pedal and
could control just how engaged it was etc... But now there is still the same
range of motion, but the pedal engages much sooner than it used to. Much
nearer to the floor than it did before the abrupt change. Any idea why this
would happen? What should I be worried about happening next :-) The clutch
that is in there is 'like new' and was installed only about two weeks ago
when I had the engine replaced with one that had all 4 cylinders firing :-)
Any suggestions, thoughts or reasonable warnings would be appreciated.
