DC wiring connections Connecting a dual output charger to two serial-connected 12V batteries (24V system) Connect each set of output to each 12V battery. The jumper can be left connected between the two batter- ies during charging. Connecting a dual output charger to two parallel-connected 12V batteries Connect one set of output to each 12V battery.

DC wiring connections Connecting a triple output charger to three 12V batteries The batteries could be independent, serial-connected or parallel-con- nected. If connecting a quad output charger to three 12V batteries, connect the spare output to any one of the three (preferably the weakest) batteries.
Operating instructions OPERATING THE CHARGER Install the charger and make appropriate DC wiring connections according to the diagrams. Choose an appropriate setting on the Battery Selector (page 12). Plug in AC power cord to a properly grounded outlet. Avoid repeatedly bending a section of the power cord.
Troubleshooting ALWAYS DISCONNECT AC POWER CORD PRIOR DANGER: TO MAKING ANY DC WIRING CONNECTION CHANGE OR WHEN CHECKING FUSES. TROUBLESHOOTING Problem Possible Cause Solution Check AC input connection. Try with a dif- No LED On No AC input ferent AC outlet to make sure AC power is present.
If the charger performs full, completed charging cycles in both tests, it may be a connec- tion error from the previous set up. If the charger returns error LED in both tests, contact Powermania to check for warranty coverage. MAINTAINING THE CHARGER The Powermania Turbo MV3 charger requires no specific maintenance.
Other Information FUSE REPLACEMENT INSTRUCTION • Make sure the charger’s AC power cord is unplugged. Disconnect all the DC outputs from batteries. • For models using cylinder (AGC-1) style fuse, pull the fuse holder straight apart. Do not bend the fuse holder as it will break the fuse inside. If necessary, use a hairdryer to warm up the fuse holder and adding grip could ease pulling it apart.
