    Well, when I switch battery on I hear a relais klick, not sure which one (and I have the daughterboard as well installed).


    When I measure the coils (VDC) and across the diodes (all the above you mentioned): I have always no Voltage across the coils, no matter if battery is on or off…which is weird as I hear at least one relais clicking…but maybe there is anotherone activated (maybe on the daughterboard) ?
