Voltage Regulator local, clutch

[klaucke]

Wondering where my "external voltage regulator" is -- I have a 1974 911S 2.7 w/ CIS. By external, does this mean outside the alternator, but still under the fan shroud, possibly attached to the alternator? Or is it near the fuses in front or under the fuse panel in the engine bay?

The reason I want to know is because the red light is always on. Once I get to the voltage regulator, can it be "bench tested" or somehow checked to see if it is bad? I already went and checked grounds, terminals. I have yet to check on the voltage at the battery.


2nd question- my clutch appears to function well, if I pause between gears, however, I can't "pull the clutch back" to check for freeplay. Is this a problem?

Thanks in advance.

here it is on my 75
above the noise suppressor which i highlighted by my flashlight

you are going to have to see what is happening at the battery first. put a multimeter on with the car running, how many volts are you seeing? no sense taking anything apart without gathering more info first.

about the clutch... what are you trying to do? is the car grinding going into gears? or slipping? the term freeplay confused me too. if you take the wooded board under the carpet up, and look at the pedal cluster, it makes more sense. you really cant pull the clutch pedal towards you. it will pivot and immediately hit the floor. i think the one inch freeplay you are looking for is jiggle in both directions. to be honest, my car goes into reverse and first better with alot less than one inch. i kept sliding under the car and tightening the nut. i was suprised by how much i needed to adjust it, after installing the new clutch cable. be happy, our cars are easy..

My floorboard is gone, but when I say I can't pull the pedal backwards, I mean at all. It physically won't go back, nevermind hit the floor. There is a stop between the brake pedal and clutch, it's slighty backward and above of the pivot axis, which prevents either the brake or clutch from coming back.

The car doesn't "grind" going into gears, but if I don't wait a moment, I will feel a mechanical feeling through the shifter. I'm not talking throwing it from 1st to 2nd as fast as I can, but just shifting swiftly, such as under accelleration. I'm not sure if your 75 has the same clutch lever release arm system, as they used many types... mine has no helper spring etc, just the cable and arm. Maybe it is the helper spring which pulls the pedal forward slightly on other cars, allowing you to "pull back" the slack that it has created?

same thing on my car, no helper spring. just cable taking a 90 degree turn into a nut. nothing fancy. i cant blast into second either. but i shift like crap. i know the stopper you mentioned, same thing. but mine get to the floor around the same time. but i think something in the tranny takes the slack back out. but i havent studied that too much so i am speculating. my car shift like yours. you are going to have to post some pictures of your car. emerald green? sounds tasty looking...

I did a voltage test:
-With the engine off and accessories off, the voltage is 12 volts exactly.
-With the engine running [fresh air fan running etc, but no lights] it is a 11.5 volts exactly.
-With the headlights on, it drops to 11.25 volts
Engine RPM has no affect at all on the needle.


What does this mean? Is the voltage regulator no good, or are the diodes in the alternator likely the culprit? Maybe brushes? Thanks in advance.

tranny/clutch wise, my cable does not take the 90 degree bend, it keeps going straight, through a V-shaped piece that fits into a notch on the throw out arm. The adjustment nut in turn touches the V piece. When I soon get my digital camera I'll be able to post pics.
