(on my 28V system, the batt is 24, main alt is 28, and = backup alt is 26) Spikes to 16 probably not a problem, but sustained high voltage = increases current everywhere, thus heating everything more than normal = -- system components and the battery itself, which sees a significant = increase in charging current.=20 On Jan 23, 2013, at 7:36 PM, Paul Miller wrote: BandC.biz has lots of data on regulators, says 13-15 is normal range.
