OCS-OCIL Circuit

Disconnect OCS switch. Measure resistance between test pin No. 41 and test pins No. 37 and 57 at the breakout box. Measure resistance between test pin No. 32 and test pins No. 37 and 57 at the breakout box. If resistance(s) are greater than 10 k/ohms, remove breakout box, replace appropriate switch and rerun QUICK TEST. If resistance(s) are not greater than 10 k/ohms, repair short circuit(s), remove breakout box, reconnect ECA and rerun QUICK TEST.
