Anyone familiar with what's involved in replacing the backup batteries in An old Hoskins CFS-1000 fuel flow?
Thanks.
Thanks.
No personal experience with Hoskins fuel flow instrumentation.
The manual only indicates that the batteries are mounted in the rear of the instrument case, using 3 each MS76 Eveready or Equivalent and that annual replacement is recommended.
