2.4 altinator and cylinder confussion

[yoh!!!]

Hi

Currently I’m helping a friend fixing some of his 1974 Porsche 911T 2.4 problems…
So far we discovered that the alternator is not charging the batteries. After removing the fan shroud we noticed that the alternator has no internal regulator (probably normal for a early 70’s car, also the same on my 914). Nevertheless we were not able to locate an external regulator. My question is now…
Where is the external regulator located???
What is an appropriate procedure for testing the alternator???

Further I noticed that the mounted cylinders are made of aluminum. While investigating this further I noticed EMPI logos on the cylinders. Somehow I expected those cylinders to be Mahle or Kolbenschmitt. Has someone here on the forum any information about the EMPI cylinders???

Thanks for your information,
Patrick


!!! Of course I ment Alternator and not Altinator (sounds like it comes from a cheap German Supermarket chain... :-) )

Patrick,

There seems to be some confusion about what year your friend's car is ... the last 911Ts and 2.4 engines were built as 1973 models!

As to the regulator, it is mounted on a panel commonly called the 'console' and is bolted to the left side of the engine compartment under a black plastic cover. Test the alternator off the engine by taking alternator and regulator to a motor/generator/alternator repair shop.

As to the 88 mm EMPI cylinders, they were made by Mahle, and are the same quality as early '67 thru '73 'S' components, being of Biral construction, and the pistons are forged, slipper-skirt high-compression parts with valve reliefs suitable for 'S' or 'Solex' cams!!! Much better than typical 'T' engine components, too!
