I would like to do the tests on alternator and cables described in a post of Ahsai on June 25, 2013.
Some of the tests involve connecting into the alternator output called ‘A’ in the post. I have trouble in locating ‘A’ on the back side of the alternator using an inspection mirror and I am not sure about how to make a reliable connection into it with the test cable. The post mentions the use of a J shaped hook attached to an insulated wire, but I don't know what the connection point looks like and where it is. I am also concerned about the risk of causing a short.
Any suggestions on how I should proceed?
Late 2004 Boxster Base Tiptronic with 45,000 miles
I have racked up 15,000 miles over the last 3 years of ownership. The coolant was flushed about a year prior to purchase. I think it's time to flush the coolant. I plan to buy the Airlift tool - it's a time vs cost issue, time wins.
I know from searching that JFP has recommended to others to replace the water pump as preventative maintenance on a car this age. Fair enough. Porsche pump, clean the mating surfaces carefully and:
1. Use gasket sealant or no sealant?
2. Should I replace the coolant reservoir even though I cannot find anything wrong with it?
I'll replace the thermostat at the same time.
3. Should it be the 160 degree thermostat?
3a. I notice that the car runs between 190 - 210 degrees (using Scangauge) most of the time in warm weather, so will the 160 stat be a benefit?
4. Which hoses should be replaced?
5. Anything else?
Since the start of ownership I've done mostly preventative and general maintenance with very few actual failures of any kind. With that being said, I think mileage is beginning to expose some common failures cropping up like what happened yesterday - the turn signal stalk won't hold in-place, so now I need to replace it but at least getting the 4-stalk version will give me the OBC functions.
I am considering keeping a jump starter portable external battery in the car. I am wondering if this battery could be used, when connected to the car electrical system through the cigarette lighter socket, to power the car electrical system to allow me to drive back home in case the alternator fails and the car battery is low. Vendors claim that the car could even be started using the external battery connected through the cigarette lighter socket.
Is there any risk of damaging any car electrical system components doing this?

I recently had to replace the water pump on my 2001 Boxster. This all went fine, however, the red light to the right of the temperature gauge is blinking at 1 Hz. I've read this indicates low coolant level. I followed the factory procedure to bleed the system and it is filled to the max, but the light still blinks. Also, the gauge is flatlined to the left. I replaced the temperature sensor near the #4 cylinder head without improvement, and the wires "look" ok. All the fuses are good. Does anyone know the procedure to troubleshoot this wiring? Or the pin and socket numbers for the wiring diagram? The temperature gauge worked fine before the water pump blew up. I did recover most of the impeller, but a few small pieces are in there.
Can anyone help me out in finding the part number for the voltage regulator found in the Altenators of the early MY CTT?
In my search I have been looking via the Delphi brand, the stats of 190A water cooled and a part for Mercedes alt comes up but nothing I can cross reference to the Cayenne.
When i had it rebuilt (brushes, slip rings, bearing) they neglected to grab part # while inside. I now have to re&re alt as it's still not working right and voltage regulator is suspect. Huge TIA.
