Relay failed to change state up(m being energized during a ~raticmal test.

Zhiture M)s attzibuted to a ~rt circuit of the wirding at a point near the beginning lead of the coil due to inadequate placement of a separation tape used to hold the beginning lead in a charnel in the end flange of the coil spool.

2m ~x)se of the separatim tape is to hold the beginr~ lead in place to prevent abrasion fr(m the subs~
