Hi,
Since I've installed a SurePower 1315 my starting battery is loosing
energy.  Over the night the starting battery gets so low that it won't
start the engine.  I've disconnected the auxilliary battery and the next
morning the starting battery was able to start the engine. The unit
works OK, when the voltage of the starting battery is equal or greater
the 13V the unit kicks in.  Can I have a bad unit?  I've checked to see
if I had continuity between the wire comming from the starting battery
ang the wire going to the aux battery.  The circuit is open.  Any
comments are welcome.
Best regards.
