[TenTec] Paralleling power supplies for Hec II

[Harry Coates]

Actually the Herc II is wired for 4 separate 25 amp power supplies, like the 9420..  1 for each of the 4 final output units, and they should each be protected with separate 25 amp fuses.. The Herc II monitors each of the 4 power inputs separately to make sure they are all alike.. They should not be tied together in any fashion.. It would be alright to parallel at the power supplies/batteries, but, the feeders to the Herc II should  be 4 separate circuits.. Not 1 big fuse or even 2 large fuses.. Check the power input schematic in the manual...     “TEN TEC FOREVER AND RTTY TOO”
