• 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.
