Trickle Discharge

>>>>> I have an Ample Next Step Regulator for two battery banks, a house bank and a starter bank. Recently I had a yard install a smart charger which charges the two battery banks when under shore power. Since that install I have experienced my starter battery bank going flat (after being at anchor for a few days with minimal alternator charging) - this happened when seeming the only load that was on the electrical system should have been utilizing the house bank. When the yard installed this new charger they wanted to save some dollars by wiring the outputs of the charger to two terminals on the alternator which eventually reach each battery bank.

QUESTION: If a convenience battery charger output is wired to the alternator outputs (two of them) could this have any impact on the operation of the Ample Next Step Regulator? Thus result in an unexpected trickle discharge of the starter bank?

1. The wiring as done won't give you a trickle discharge.

2. Wiring is amateurish at best.

3. The battery charger probably has a small drain when there is no shore power.

Thanks for the quick response! Yes I was doubting the wiring solution myself and appreciate your comments on it. One would think that the battery charger would be designed to isolate itself when power is dropped - I will devise a way to disconnect it from the system when away from the dock and see if the system works as it used to.
