• Failure rate of PEC’s was slightly higher on the ZTR tester through 3 months.

• Replacing all relays during repair does not improve reliability.

• Additional testing of all PEC’s and failing any over the 60% mark during repair, will prevent short life PEC’s from being shipped to customers.

• LTX have already implemented the above measures in repair.
