The autopulse platform in complaint was returned to zoll on 01/08/2015 for investigation.Investigation results as follows: visual inspection of the returned platform showed that the battery connector of the power distribution board (pdb) at j2 and the encoder cover were damaged.The damaged battery connector of the pdb found during visual inspection confirmed the reported complaint of the platform not powering up.The physical damages appear to have been caused by normal wear and tear (autopulse manufactured in 08/2004).A review of the autopulse platform's archive was performed and showed that no sessions occurred on the reported event date of (b)(6) 2015.However, the archive showed that multiple user advisory (ua) 3 (error communicating with battery controller) occurred on (b)(6) 2014.Functional testing was performed using a test pdb and the reported complaint was not reproduced.The platform ran with a test manikin for approximately 7 minutes and no problems were observed.Based on the investigation, the parts identified for replacement were the pdb and the encoder cover.In summary, the reported complaint of the platform not powering up was confirmed based on the platform's archive review and during visual inspection.The fault was found to be due to the damaged battery connector of the pdb.The ua 3 fault observed in the archive review was found to be due to the damaged battery connector, which likely contributed to the platform not powering on.The damaged encoder cover found during visual inspection is unrelated to the reported complaint.Upon replacement of all parts, the platform was re-evaluated through functional testing and passed all testing criteria.
