Eco Charge EC-90 schematic
« on: October 02, 2011, 10:53:13 PM »
Does anyone know where I could find a schematic for the circuitry under the cap for the EC-90 battery?  There's no response from the Eco Charge website.

thanks

Not a schematic, but you might want to check out this thread if you're looking to replace a dead batt.

Have you tried drawing it out yourself?  I wouldn't think it's too complex of a circuit and is probably only a two layer board (top and bottom).  Are the components marked?

I already replaced the battery a few months ago and it worked fine for about 5 times.  Then suddenly, I get no power on either the 7.5V nor the 12v sides.   Seems to charge ok and the battery is not the problem (I'm told).   My electric guy found some old electric component to replace on the board, but he's not optimistic.  So he was wondering if he could get a schematic.  Sadly, I'm not skilled in this area.

thanks for the replies.
