This ARC IN-386A Converter is sold as-removed, offered with no warranty and reported working when removed.

Condition is as-indicated; however, the part has not been checked by an A&P / IA. As with any part you install on your aircraft, your A&P should perform due-diligence and ensure airworthiness prior to installation.  If you determine this does not meet your requirements, return it to me within seven days for a refund.
