I’ve lost the instructions to mine and wonder why the charging light is blinking. It’s normally constant.

For some reason there are no instructions on the web that I can find.

It's described as a three stage charger. That would be bulk, absorb and float. Bulk is where the charger provides maximum current to battery until it's pre-set full charge voltage is reached (usually around 14.3 to 14.8 volts). Absorb is where that same voltage is held for an automatically calculated time during which charge current demand tails off, and at the end of which it's nominally fully charged. Float is a lower maintenance voltage (around 13.2 to 13.6 volts) in which state the charger can be left on indefinatly.

Depending if it happens at the beginning of a charge sequence or some time after, the flashing green light probably indicates bulk or absorb mode.
