Billy, I don't know what brand it was...there was no brand id that I could see. My Ftech thought it was a Bosch without looking at it. I only know it was 120A. The guy who rebuilt it says that they get burned out by starting and running the car with low battery charge. I have done that only a few times. Go figure. Battery is holding charge at 14.5 v now, which is what the alt is now putting out. Jim | ||

Congratulations, Jim. Not too hard I suppose. Just think if you would have taken it to a dealer they would have charged you $1,500. Mine is running fine now. Out of curiosity is your alternator a Delco Remy as well? | ||

OK, fixed at $140 for new rectifier (dodad that converts A/C to D/C). 4 hr job for me, plus running around. Oh well, at least my ride is in excellent condition again. Lets hope that is the end of my mechanic fun for this summer.  | ||

Well, it was not a serpentine belt, and it took 2 1/2 hours to deliver (bout the same as a baby). It is a 120 Amp unit. I am told I might have the 512TR engine in my '91 Testarossa. The boggle was the radiator piping lined up precisely in the way of the alternator belt up against the firewall. It had to be loosened. Also, the bolts were all very tight and there was very little room to maneuver. Oh well, its done and now (tomorrow) it will be off to the alternator shop. | ||

I am quite sure mine is a serpentine belt, and hopefully, it will be just as easy to do. Tx. | ||

No it has its own belt. It is behind the AC compressor belt so it is easy to line up. That was the easiest thing to do. | ||

Billy, I guess you didn't have any trouble with belt re-installation. Just curious, does yours have the serpentine belt config? Jim | ||

I just changed mine a couple of weeks ago-fairly simple. You do not have to remove the intake just the surrounding pieces. There are 2 bolts you loosen on the alternator one of them being the tensioner bolt. It took me twenty minutes to do it. It is a delco remy alternator and you should have it upgraded to the 110amp one rather than the 90amp that is in there. Cannot tell you how much better my car runs since I put it in. My car would run on alternator then it would shut itself off and run on battery and the car would run sluggish. Now it is running great. | ||

JRV, It is a '91, and the intake plenum runs to the rear of the car so I don't think it is in the way. I was mainly worried about the serpentine belt popping off a pully down below where I can see or feel and then not being able to get it back there being VERY LITTLE room to maneuver. I appreciate your input. Thanks. | ||

Jim, IMO you will make the job far more striaght forward by removing the parts you mentioned and then removing the intake plenum. This will give you more room on the backside and also allow extraction of the Alt. once it's unbolted. If you have the serpintine belt, then you either have a later TR or the updated pulley setup. From the top you can refit the belt upon reinstalation without a problem imo. I take all my bad Alt.s to my local rebuilder for bench testing and repair. My guys have uncovered many problems I never would have found by simply putting a new brush pac in. | ||

OK, so it looks fairly simple to do, but of course, I can't see the belts or even the bolts that have to be loosened except for the adjustment bolt. Pull the grill off the top behind the deck lid, loosen the belt and (BTW< is this a serpentine belt? looks like the A/C is same belt since it is inside out) remove the alternator. How do you go about keeping the belt on the other pullies or getting the belt back on without having to drop the engine? Any tricks to this job before I end up getting into some kind of quagmire? Is it a Bosch alternator? Does it have bushings that I can replace (like my 911 Carrera) or does it have to go to rebuild shop? Once again, thanks for advice. |
