Similar to a mother boards that suffers from voltage droop... that is what I am again experiencing in the Park Ave.
I was manually charging the Odyssey battery yesterday for a reason....
With a basic load on, fan on lights on & brakes lights on at idle, volts drops from interior accessory socket reading to 12.2 -12.4 volts..that is huh?? Should it not be kicking out at least 13.6 volts?.
This is always after driving when it gets hot outside.. doesn't help either..
At 1800 rpm with same load, I am lucky to see 13.4 volts....this is not charging the battery very well. This was happening with the other stock alternator before I ordered the high output & it is doing the same thing again with the new ALT. With the c-tek manual charger it was putting out 14.64V
Most cars can & should put out/charge easily at 13.9+ at highway speeds. I will get the ALT loads & Diodes Tested again by the snap on machine soon...maybe something up with PCM module?
Ok onto my next question for you electronic tech savvy folks...CS-130D alt..160 amp..
For those that know the laws..could it be the greater the amperage output the lesser voltage rule going on here?
There is a 4 wire connector one of which should be the exciter wire, which as far as I know is what tells the alt to get with it and put some volts out...
From what I understand installing a diode (not sure which one) into the exciter wire, u can fool the ALT into seeing a lower voltage than is present, and hopefully then the ALT kicks out another 1/2 volt or so...anything would be better than what I got...
Thanks for some info & help I need some more volts please!
I found Dan'* tech write up I am not sure that applies to my 97 4 pin system though?
Adding a sense wire to your alternator.
Note to eliminate confusion I decided to create a new Thread for this issue.
