Battery Pack Test (2523)

1.  Remove the battery pack.
2.  Measure the voltage at the battery contacts as shown below.

Contacts	Voltage (Vdc)
+	+9.0 to +12.6
-	Ground

•  If the voltage is not correct, charge the battery.
•  If the voltage is not correct after being charged,  replace the battery.
•  If the voltage is correct, suspect a short circuit or failure in the  computer. Go to the 'Short Circuit Test'

1.  Measure the resistance with an ohmmeter between the T  and - contacts.
2.  The resistance should not be open (infinity).
    The thermal protection is detected when the temperature exceeds  70°C to 80°C (158°F to 176°F).  Wait until the battery temperature becomes normal, then  verify the resistance at the battery terminals. If it is open, replace  the battery.
