I have a brand new multiplus 12/3000
The trickle charge output is connected to a 12 volt 140 ah battery. The voltage is 12,87
When i turn on the multiplus the trickle charge wont charge (i have a smart shunmt connected to the starter battery) and when the multiplus goes into float status also nothing will happen.
When i disconnect the trickle charge cable i measure 4 volts on the trickle charge outpul.
Is this supposed to be? Will trickle charge only charge when reached a certain battery voltage level?
Best regards and thanks in advance!
