PNDB Power Net Distribution Box Fuse Cover and label MIDI Fuse Output 300Amp Max Power Net Distribution Box (PNDB) ATC Fuses The PNDB is a new power delivery system for the WST and is designed to deliver more consistent and better protected power to the other components on the truck. ATC -B ATC -C ATC -D Primary Solenoid for Cut off Switch battery ATC -A The PNDB also has protected “keep alive” circuits that will maintain power even with the cutoff switch in the off position. The primary reason for this change is to provide power to the 2010 DEF purge system which drains urea from the delivery system and prevents the system from freezing during cold conditions.
ATC Fuse Output Battery Input Primary Solenoid Cut Off Switch Connection The PNDB located at the lower LH front wall area is equipped with three MIDI fuses which supply power to the Main Power Distribution Module. These fuse connections have been relocated from the battery in 2010 to prevent corrosion and improve the trucks reliability in severe conditions.
