I just installed a Noppondenso 140A factory upgrade kit. For comparison, I have the following readings: 1. Start-up (cold), all accessories off 14.2V 2. Turn on the AC and lights - 14.0V 3. Turned on the high-beams - 13.8V 4. Turn lights, AC, let the fans kick in 13.5V
Those are very nice numbers. Did you measure these voltages at the battery or at the cockpit (say cigarette lighter)? What was the damage in terms of $$$ for the upgrade kit?
All voltages measured at the battery. About 6 months ago, I was lucky to win (auction) the complete brand new kit on Ebay - alternator, lower bracket, upper bracket, 2 belts, all related bolts and nuts and the wiring harness (which is only required if you are upgrading from AC Delco). All for $770. How's has your alternator been doing so far? Image Unavailable, Please Login
Just some food for thought... My 930 alternator recently went out. A new one is $800 off a porsche web site. I went to pep boys and the exact same rebuilt alternator was $108... Shocking. Lifetime warranty. Same manufacturer, same model. The thing that worries me about a pep boys type alternator rebuild is that they are built with cars the drive at 1500 rpm in mind. They are NOT built with a 6000 rpm cruise in mind. The load on the bearings goes up exponentially as RPM increase... So, I went the middle road. I kept the original alternator and bought higher end bearings off a website ( they had skf/and the original Nachci (sp?) japanese bearings that were on it). Total cost $35. Pepboys also had the bearings, they were no-name, and $10. I am sure thats what is used in the rebuilds. Took an hour to replace the bearings (and 8 hours to put the danged alternator back in!). Voltage regulator was $50 for a new one... Plan to rebuild the testarossa alternator also, as the bearings are rough... plan to do the same as above... If you take your alternator to a shop that does rebuilds, ask for the highest quality/expensive bearings. Not the cheap chinese knock-offs... Bo
No complaints - I have driven the car with various electrical loads and seems everything seems to be working fine.
