Question:
Change ing. 6volt to 12 Where do you hook up the charger

Expert Reply:
The CTEK MULTI US 3300 12-Volt Universal Battery Charger w/ Pulse Maintenance # CTEK56353 is only a 12V charger that will allow you to connect the lead wires to the battery terminals with either spring clamps or ring terminals.
For a charger that can charge both 12-volt and 6-volt batteries I would use the NOCO # 329-GENIUS5.
If you are wanting to charge between the two batteries, that is not a directly compatible option. You could however charge two 6V batteries wired in series with a 12V battery. I've attached a photo to assist. Then you can use a DC to DC charger like # 331-BCDC1225D to charge while driving if it is a trailer application. For more assistance, I need more information on what you currently have and what you are looking to do.
