WB Jr stopped working! Help!
« on: August 12, 2017, 12:32:20 PM »
Every thing has been working fine, then this morning I wake up to low battery with full sun. Kid says "check WB JR wiring". Looks all fine and tight. I don't see WB Jr blinking anymore. No storms but suddenly dead... I'd like to quickly circumvent the WB Jr but when I turn it off it still says check WB Jr. I hear a relay constantly clicking too. I'd love to charge my most precious batteries.

Any thoughts??

Turning the Settings to OFF should have done it..

Have you tried a factory reset?  That is the first step  to see if the gremlins are looose in your KID>>  other wise disconnect the WBjr wire first,then remove it from the shunt if no change

So, is the Kid charging ?   If so, do you have a voltmeter that you can check the voltage
coming out of the Kid and going to the WB Jr. ?  It should show something around 12V to
14V DC or so.

The signal back and forth to/from the WB. Jr. pulses low but is mainly sitting at around 12V DC most of the time.

After turning the charger on and off a few times it is finally charging the batteries but still says check WB JR wiring. I'll try all your suggestions when I get back from vacation. Thanks,
PK
