I have started this thread to gather information on what battery resting voltage and alternator output voltage people are seeing for the new 2.8D. The reason for this is on a few posts on other threads people have reported alternator output voltages from 13.4V up to 14V, and someone had suggested it may be a build date thing.
So it would definitely be helpful if people posted their voltages - if there is a pattern where later vehicles are getting higher voltages, then it would maybe suggest there is a software patch, and we could lobby Toyota Australia to authorize the service people to allow the voltage setting to be raised, or try to find out if we can DIY it.
Of higher concern to me is the resting voltage I am seeing on my cranking battery - before starting I am seeing around 12.4V, and sometime as low as 12V. This seems low to me for what be a fully charged battery. For example we drove 1 1/2 hours to a campsite this weekend, car sat there for 2 days then when I went to start it the battery read 12V. So if people could post their battery resting voltage before start also, that would be helpful.
So my info - Sept 2015 2.8D, when running outputs 13.4-13.6. Max I have seen is 13.8, but normally around 13.6. Cranking battery normally 12.4V before I start.
(ps - Please try not to sidetrack this thread - it has split from another thread because it started heading into the VSR vs Dc/Dc trench warfare.)
