PNDB Power Net Distribution Box Fuse Cover and label MIDI Fuse Output 300Amp Max ATC Fuses Power Net Distribution Box (PNDB) ATC -D ATC -C ATC -B ATC -A The PNDB is a new power delivery system for the WST and is designed to deliver more consistent and better protected battery power to the other components on the truck. ATC Fuse Output The PNDB also has protected “keep alive” circuits that will maintain power even with the cutoff switch in the off position.
Power Train – Power Distribution Module (PT-PDM) Module 286 Power Train (PT-PDM) The PT-PDM holds all of the power train related fuses and relays. • All engine fuses/relays • All transmission fuses/relays • All after treatment fuses/relays except DCU main battery feed (located in PNDB) • Sleeper power The power which supplies the PT-PDM is sourced from the Power Net Distribution Box (PNDB). This power is protected by a 175A fuse.
RX Module 3” WST Star Gauge System 87340-4403 Data Star Beginning in April 2005, the PX and PX-A modules were replaced by air lines that are routed to each individual Star Gauge. These gauges convert the air pressure into an electrical signal. The Star Gauge databus supplies power, ground, and backlighting information for these gauges. Star Gauges 2” 87340-4404 Star Gauges are secured in place with a lock ring, which can be removed easily using a removal key that fits into the lock ring.
