CSY-
That might mean nmore to Rick than it does to me. I don't know what
regulator you have on the
boat, buy at 14.1V either it has reduced output because it is no longer bulk
charging, or because your temperature is too hot. Or, there's a problem. Dunno which, knowing the temp & knowing the regulator's intended profile might help. Is the difference significant? Well, what you've got is either right or not-quite-right, but IIRC that was how the whole wuetion started, one of your chargers say the other isn't quite right.<G>
I'm surprised that 14.4 would shut down the reefer
compressor &
SSB though. I recognize the
SSB but have a block (SMACK! Reset. SMACK! Reset!) on the name, couldn't double check that. Most of them are specified as something like "13.8 volts plus or minus 10%" for "mobile" operations, where 14.4 is in fact the norm and 14.8 is sometimes found, convenient since there is overvoltage protection (like zener diodes) cheaply available for 15V exactly. In fact, some of Icom's
equipment is known to get downright unstable with a paltry 12."+"V, when they say it wants 13.8, it really WANTS 13.8.
I guess that's the down side to 'smart'
electronics...you never can be sure what the nasty wee silicon creatures are plotting to do behind your back. Or, even in plain sight.<G>
