Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
BST Activation
Once activated, the ignitor generates a gas charge which is directed down the internal discharge tube
This causes the tapered end of the B+ cable contact to dislodge from its seated position and immediately open the circuit.
The force of the charge continues to push the cable contact away from its seated contact. The spring tabs of the housing are compresses as the contact pushes to the end of its travel.
When the contact hits the end stop of the housing, it bounces back against the return spring which prevent it from closing the contact with the battery.
