Greetings - I have traced a coolant leak to the rear of the alternator - wondering if anyone else has seen this and whether its repairable or I just have to commit to replacing it (once I can find a replacement - they seem to be rather hard to find at the moment).... Cheers.

Hi guys.Finnally got the Boxster on the road after an enforced year stood.It sounded a bit rattly when I started it up.I have done about 50 miles in it since all short journeys, and it still making the same noise.Not knowing much about these engines not sure if it's something more serious than tapped, alternator bearing???.Im not driving it and will get it recovered to an Indy for assessment, so any suggestions will be gratefully received. Hopefully other club members will chime in.
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?
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?
As if my ctt didn't already have me well invested....... today the wife's calls to say dash warning say "battery/generator fault". FYI I think this might well be the root cause to my many gremlins like "check tail lights and licence plate lights" when below 13.2 volts and "four wheel drive faulty" and engine hesitation !!
She drove it straight home and parked it.
I checked the battery (new in Feb 2016) voltage showed 12.4 volts this is low I know, started up ok (ran very poor) but charging is 12v off load and 11.85v with lights on, so Alternator is caput! When tested before a few weeks ago was 13.72v off load and 13.2 on load.
Unless someone has any other viable possibilities? Heard of main cable fault on earlier models and fuse?
So assuming all other possibilities get ruled out I'm looking for a re-manufactured alternator, there seems to be loads of revisions and different part number across the 2003-2006 yrs, but I'm sure mine is pn 95560301610 autoatlanta listing or 948603015 ECS Tuning listing) (190amp option code I8GY as per the specification print out from Porsche for my car).
Some I found are 150amps and others for the earlier years which I think had a different electrical connector fitted?
So question I'm asking is which Bosch of other brand remanufactured part is the right one for my alternator?
Tech Info Appreciated. And some R+R DIY advice pls......
