Trying to trace the 2 wires coming out of my charger to diagnose a charging problem. Can someone tell me where the charger wires get connected to the batteries? Boat is a 01 310 sundancer. I am in the bilge as I am typing this, so I am desperate! Thanks
 
I believe that they connect at the battery switch.
 
Not sure what your problem may be...but be aware that the charger has at least one internal fuse that can cause it to fail to charge the batteries. If the symptom is AC to the charger but no DC to the batteries, I would open the charger (after disconnecting the AC) and look for the fuse. Good luck.
 
Thanks guys. Right after I posted this, I remember having the breaker panel apart under the cockpit sink and having the "converter 1,2" breakers in there. After 3 hours of diagnostics, I opened the panel and converter 2 was tripped. flipped that and all is well again. I did check the output from the charger first and all was good there. Thanks for the input.
