WARNING: MAKE SURE THERE IS NO VOLTAGE AT THE ELECTRICAL CONNECTOR.
_______ IF THERE IS A VOLTAGE AT THE ELECTRICAL CONNECTOR, THE SQUIB CAN RELEASE ITS CONTENTS SUDDENLY AND CAUSE INJURY TO PERSONS.
(b) Make sure there is no voltage between pins 1 and 2 of the electrical connector.
NOTE: Connect a 10k ohm resistor across the meter to
____ remove any stray voltage from the electrical connector.
(c) Do the steps that follow to make sure you did not bend or damage the squib pins.
NOTE: This step is necessary because the pins are most likely
____ to be damaged the first time an electrical connector is connected to the squib.
1) Disconnect the electrical connector from the fire bottle
squib. 2) Make sure the squib pins are not bent or damaged. 3) Make sure the electrical connector is not damaged.
NOTE: The squib pins can cause damage to the connector if
