I need advice on how to adjust the float voltage of this old battery charger.

The charger works just fine except the float voltage is about 13.15VDC, which is a bit low. (Shouldn't it be a bit closer to 13.8?)

So far, I can't find any schematic or circuit explanation.

I'll take any advice to reverse engineer this...measure voltages at various components...determine where I could change the value of a resistor or other component so that the float voltage is raised to the proper level.

Thanks in advance.

An old battery charger that works well, except the float voltage is a bit low.

Can I reverse engineer this and adjust the float voltage?

The top side of the internal circuit board.

Where might I start measuring voltages in order to determine what component I could change in order to boost the float voltage?

@KrajciTom@universeodon.com There are just a few points between maintained and boiled dry. I suggest staying lower.
