Default Powerwise plus proper operation

Ok, so I finally have my powerwise plus charger working on my old marathon sb50 cart. It's charging! Now my question is... what is the proper operation of the lights on it? It has LEDs that say on charge, 2 hour, 4 hour etc.. the only that that is on is the ONCHARGE light. It started at 20 amps, moved down to 10 amps, and now Is at 5 amps... the batteries are mostly full..

So I assume that if they are really low then it will light up say 4 hrs to show that it needs 4 hrs to charge???

Right or wrong?

Thanks,
Kevin

Wrong.

The LEDs have absolutely nothing to do with predicting how long battery charging will take, in fact they have nothing to do with the battery charging process. The simply indicate how long the charger has be charging. In other words, an elapsed time indicator.

What the elapsed time is for the various LEDs being on is explained on Pg-11 of attached manual.


Sounds like your PW+ charger is functioning normally. It should shut off when the on-charge voltage reaches 45V +/- 1V.

The attached charge profile is embedded in the matched ferroresonant transformer and capacitor pair.

All four yellow lights flashing means the DC cord has been connected for at least 24Hrs and it should be disconnected to reduce battery drainage.

The charger isn't actually on while flashing the 4 yellow lights. The power input board has AC power connected to it whenever AC power plug is plugged into AC power, but the charger isn't on until AC power is applied to the transformer via the relay on the power input board.

This charger will not automatically keep your batteries charged while cart is in storage.
