Energy Products CC-1292 battery charger

Hi all - anyone ever worked with one of these units? It is what looks to be a "smart" charger for the battery bank of 36 volts, but I have more questions than answers on these. I bought an E15 (not running) and it had one of these chargers fitted into where the stock timer would be located. It has a single LED and 5 different patterns spelled out as to state of charge etc. It looked to be working at first, as it went through the sensing stage and then took on the "charging" pattern, but when I check the voltage on the batteries, there was no difference with the charger powered on or off. When I removed it, there really isn't much to it. A small PC board with a few ICs on it and a few other components and only one regulator (or so it looks). There is no transformer at all (?) and the A/C comes in through what looks to be a 30 A rated relay contact. When you look at the size of the traces on the board and the wire gauge coming from the charger (maybe #18 AWG, but could even be #20), I would say that this charger is maybe capable of 3 amps charge current. This is OK as I don't really need a fast-charge option, but I can't seem to get it to work. Schematic or other information seems to be non-existent anywhere, so trying to fix it is a bit of a challenge.

Does anyone out there have one of these? Am I just wasting my time trying to get this working? I will try to post some pictures of this unit tonight so that you can see it for yourself. If you do know what it is and have info on it, that would be a great help! Ken.

Here are some pics of the Energy Products CC-1292 charger. The address still exists and I am tempted to call them, but it's unlikely that they will release anything like a schematic of the unit.

Here is a view of the PC board showing the +/- connection to the battery leads - confirmed as #20 AWG stranded wire - not much charging power here!

Well they are still in business - http://www.energyprod.com But i cannot find that model listed on their web site. I would contact them and see if they can send you a manual.

This unit is a Charge Controller, it was designed to replace the factory timer and use the factory charger. Tells the original charger what to do.

The 2 small red/black leads connect to the battery pack so it knows the pack voltage.

1 side of the 120volt AC line connects to the relay the other side to the common terminal.
1 side of the charger 120volt input connects to the relay also and the other side to the common terminal.

For this to work the original factory charger has to be in good working order.
I got 3 of these in a GE package deal from last yr.
