I’m struggling to get my 12 12 30 isolated DC DC charger to charge my house batteries. At recommended settings it charges about 15-20 amps.
I was playing about with the settings: switched off the Engine detection setting and reduced the input lockout voltage to 10.5 volts. This made the charger charge the house batteries at 30amps + however the 60amp fuse blew between the starter battery and the DCDC charger. ( I didn’t play around with the settings again)
Question. If my starter battery is on the way out will the alternator keep trying to charge it. Thus reducing the current / voltage-available for house batteries
House battery is a 480amp lithium. Starter battery is a 70amp lead acid six years old. Alternator is 75amp regular.
Thank you in anticipation
Donald.
