Hello Guys,

Few days ago, I build a lead acid battery charger from schematics that I found online.

For now, it works fine, battery is charging. I added 2 LED's to help me see where power is in the circuit (to help troubleshoot in case of failure). The problem begins when I remove DC power supply, the LED's are still lit but slightly dimmer. What am I missing from the circuit?

Found it, thanks guys (and gals, if any). D1 is P6kE6.8 - breakdown voltage around 6.8 V, and that's what's getting back into the circuit.
