I've put in Z14 as described by Nuckholls. I ordered then returned the speced B&C solenoids for the main, aux and cross feed duty and replaced with Cole Hersee 24213 200amp continuous solenoids w/ N5408 diodes because the B&Cs ran too hot to touch (120F) at 14.1V buss voltage.....and because they were obviously CH knock offs (and B&C wouldnt give me a techsheet on them). Sure enough the CHs run just as hot. Each is pulling spec 1.5amps.
Are these solenoids supposed to run that hot in regular duty? Theres little or no current going across the contacts as I'm still in panel build mode, so this is all coil heat.
Seems logical that the CHs should be able to take 14v since thats charging voltage, and I'd hate to replace these with Gigavacs if this is "normal". But too hot to touch doesnt seem normal....
Any help greatly appreciated.
