Lucky Lark Battery Pack With Audio Amplifier

Hi all,

I bought a used LL off ebay recently, it looks a good unit however it came with no instructions can anyone help out with a few pointers please?

My first question is does the green light come on solid when charging (it flashed yellow and green when I first plugged it in) or is the charger telling me its fully charged?

My second question is, is it hard to get to the trim pot to change voltage output?

Thanks in advance

Jim

Hi Jim

The lucky lark charger I have has a single multi colour LED on it. Before plugging in to charge these units make sure you put the charge/use switch in the charge position (otherwise you with blow the fuse). When initially charged (depeleted) the light will be solid red. When the unit is nearly charged(say 85%) it will be partially green partially red (depending on which angle you look at it will have more or less of each colour). When completely charged it will be solid green. The charger unit will flash as you say when first plugged in but then should go one of the previous colours metioned above depending on it state of charge.

Changing the voltage is easy as. Simply remove the screws from the top cover, with the detector battery cable attatched to the battery insert your multi meter into the + and - terminals. There is a small plastic trim pot in the middle of the board (mine is blue) simply wind this up very slowly to the required voltage.
