Bulletin Summary
Pierce apparatus equipped with Command Zone multiplexing uses the cab power distribution area for determining the vehicle system voltage. However, because of voltage drop between the batteries and the cab distribution area, this is not a true representation of actual system voltage. To improve the accuracy of the Command Zone voltage gauge, a 10/2 harness will be run from the right-side battery box to Output module #1 (or Input Module #1 if Output module is not present on apparatus). This will provide a more accurate voltage input to the module responsible for populating the voltage gauge value.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
