REPLACING THE FUSES

There are two fuses located within the 9v battery connector wiring. PME supplies two additional spare fuses with each system along with a 9v battery connector assembly. This assembly can be installed and used while the faulty connector is being repaired.  Determine that the fuse is defective by measuring resistance. Good fuses measure about 6.5 ohms. Blown ones are much higher.

  1. To replace a fuse, remove the batteries.

  2. Unplug the connector wiring and cut the shrink tubing.

  3. De-solder the bad fuse and install the new shrink tubing.

  4. Solder the replacement fuse in place and shrink the tubing. Fuses blow for a reason. Try to determine the reason before re-connecting the batteries.
