Crane Fireball Ingition Boost Relay

• The starter boost relay is the answer to weak starting performance

• When installed, it improves and/or eliminates the voltage drop in singlefire applications during cranking

• It boosts the coil voltage but does not connect to the starter

• Applies full battery voltage to the ignition (module and coil) and gets rid of the 1 to 2 volt drop in the original equipment wiring harness
