I have the new charger to and I used it to heat the wire on frames to install wax foundation

You need voltage meter and if you open up the charger before the safety switch you will have voltage
Easy is to check the voltage before safety switch and 12 V Clams In some point you will find voltage
Then I solder wire with small clams at the end (make sure is well insulated) because you will have voltage all the time between this wire and 1 of the clams is the charger is powered
Don’t charge battery whit this wire!!!!!!!!! Charge the batteries whit the original what come whit charger
They have this kind safety because batteries can explode!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
