My 2011 Honda Odyssey, 180K miles, has been showing a "Change Batt" indication along with a red battery light. Battery is 6 months old and the alternator has about 50K miles on it. The alternator was installed by a dealership about 2 years ago. The van starts fine. When I check the battery voltage, ignition off, it reads normal to somewhat high, about 13.5 volts. With the ignition on, it reads close to 16V. I took the van to a dealership for troubleshooting and what I got was 1. replace front spool valve. The idea is that it is leaking oil onto the alternator, causing it to fail, 2. replace alternator.
I just replaced the gaskets in the front spool valve and replaced the alternator with a Denso remanufactured alternator from Rock Auto. Voltage problem is the same - nearly 16V with ignition on. The old alternator that I pulled from the van did not have sludge or signs of oil on it. I'm at a loss. Anyone have any ideas?
