Might be a bit of a read. But dear god I need the help. lol
So. First off. Battery on my 156 2.5 V6 was dead, and from what the roadside assist guy told me. The Battery was old and "open" too, so I needed a new one. On-top of that, he told me my Alternator is under-performing. Showing me a reading of 12.2 Volts of it when it's charging, then told me it's meant to be charging 13.5 Volts. So I got a tow truck to be sent to a "Auto Electrician" he recommended to repair the alternator for me. Expecting since it's not that underpar should be just a brush replacement or something simple.
I call the mechanic later that day. Told me he has to remove the bloody subframe to get to the alternator, and its going to be a big expensive job ect ect... Told him there's far easier ways to access it. Told him I know a few guides and I'll send him them. "Said na na I'll do that myself" Would be nice if you did that BEFORE telling me it's going to be a big job... 1 day after him having it asking him whats going on again. Tells me that It's still going to be a big job. Needs to move the engine forward and ect ect. Will require 6 hours of work AND he said I need an entirely new alternator and quoted me 1.5K!!!!
As the one I've got "has oil on it" Which is a good indication it doesn't work at all to him... Even though I told him it's still making 12.2 volts! I know it can't be that bad as I check my levels regularly and the only leaks I have at the moment is my power steering and that's relatively minor. Told him he could still access it still connected to the Car and find the issue that way. As tried to explain to him theres on a very detailed forum post on how to do exactly that.
He got a bit ****ed to say the least... Said he can barely see it let alone work on it and a few naughty words inbetween...
Anyway. After scourging the Alfa Forums. I found a comment explaining that a 156 V6 alternator is normally performing between 12.5 to 14 volts anyway.
Is that true? So is there really an issue with my alternator at all in that case?
And could the alternator be properly worked on still attached to the engine?
I find a view guides to get to the car from the bottom, yet, alot of comments saying the best way is from the top. Could anyone here clarify the best way to get to alternator in the 156 2.5 V6?
Thanks for the advice in advance. Definitely need to know about the regular voltage output of the alternator though
