Product Overview
JLG's parts information specifies 3740067 as a 12V 200A relay/solenoid assembly. That corrects the 100A rating found in the source title. High-current contactors can fail through burned contacts, weak coil operation or terminal damage, causing intermittent or complete loss of the circuit they control.
The relay is associated with multiple JLG boom-lift platforms, while exact usage can depend on machine serial number and electrical configuration. Compare 3740067 on the removed component or parts manual along with terminal layout and coil voltage.
