Piper PA-44-180 SEMINOLE Maintenance Manual page 215

The torque method for checking alternator belt tension is given as follows:
1. Apply a torque indicating wrench to the nut that attaches the pulley to the alternator and turn it in a
clockwise direction. Observe the torque shown on the wrench at the instant the pulley slips.
2. Compare the torque indicated in Step 1 with torque specified in the following chart. Adjust tension
accordingly.
The higher tension specified for a new belt is to compensate for the initial stretch that
takes place as soon as it is operated. These higher tension values should not be
applied to belts which have previously been used.

BATTERY.
The battery is located in the nose of the aircraft and is accessible by opening the hinged fiberglass nose which
tips forward, and then removing the battery box cover. (Refer to Figure 24-2)
In the past, aluminum cable was used in wiring the battery circuit, battery to ground,
battery to master relay, master relay to starter solenoid, starter solenoid to starter and
engine return ground wire to airframe. (See schematics for your airplane) If, during
inspection, a fault in the aluminum cable is found, Piper considers it mandatory that
the complete cable assembly be replaced with copper wire and suitable terminals.
