A brand new circuit board for a rescue fire truck can cost more than $3,000 to replace, regardless of why it has malfunctioned, but fire truck maintainers from Joint Base Lewis-McChord, Washington dug a little deeper into the issue and discovered a $2 solution.
Recently, the shop was faced with replacing one of their own dashboard panels as a truck began displaying a compartment open light in error. Maintainers were able to trace the issue to the power distribution panel in the cab of the truck and discovered a transistor had failed.
