Thank you to you all for sharing your thoughts and recommendations.
Pud237: Your info was very much appreciated. I have since learnt the model number for my alternator and also learnt alot about the ePer and also alfa related diagnostic software. Thank you!
Fred: Thank you for the warm welcome, i took your advice and called Andrew (i live on Marrickville Road) and had no idea there was an alfa specialist so near by!! He's quoted me approx $1100 for the entire job with a recon part... stated the same about the turn around time, up to 3 days depending on wether he has the part available or not, maybe they all source from the same supplier. Looks very tempting, i might even throw in a service as it will still come in under the original $1700 quote.
Shiny: Dont know where to start... i feel somewhat honoured to receive some of your advice (no disrespect to any other members), i originally signed up to this forum simply to follow your GT related posts! ( i might PM you soon as im on the market for an aftermarket radio and need some recommendations)
My car was looked at in Ashfield by some little alfa garage... dont recall their name. dont think i want to.
I went to Alfamotive in Marrickville this morning and Andrew (very nice guy) tested my voltage and agrees that the alternator is not functioning properly. I dont know much about alternators but when he plugged it in at idle it was showing 11. something and slowly climbing on the reader - Andrew tells me it should read 14 or so. Ok... If it's the alternator or the regulator would baffle me as my understanding of electronics is minimal.
Craig_m67: The alternator replacement on a V6 is a difficult one im told (3-4 hours labor).
Leading up to this diagnosis, here is an idea of what i've done to my car to resolve this:
1 - Original battery needed replacing so went to battery world (First mistake, never again!)
2 - Battery World replaced it with a good spec dry cell battery ($500)
3 - The battery did not sit flush on the car so a day later, my car went insane, shutting down all electricals and then just dying - found out that the midi fuses (here comes my electrical expertise - red and brown fuses) in the fuse box had been cracked during the battery installation.
4 - Went to Sydney City Alfa Romeo who replaced the battery, fuse box and fuses ($450), Car ran fine for a few weeks.
5 - Now im getting the error messages again - all fingers are now pointing to the alternator. I'm hoping this will resolve this issue... hoping.
I'll keep you all informed on how this repair goes.
On another note, i need to source a new cigarette lighter and holder and the driver side power window switches as one of my switches is broken - my info is that the gta window switches wont work on the GT due to the frameless window - as after closing the door, the window actually shuts into place on a GT and not on a GTA? Does anyone know if this has anything to do with the actual window switch?
Thank you again to all of you for your time and effort in helping me.
