5 step to troubleshoot battery charger
Step 1
Make sure the charger cord is plugged in and the outlet is getting power.

Step 2
Look closely at the battery pack. Is there corrosion or leakage? If so, replace the battery immediately.

Step 3
Test the charger. For DC chargers, set a voltmeter to 25 VDC and touch the contacts with the probes. The meter should read about 1 V more than the charger's rating. If the reading is zero, switch the probes.

Step 4
Test an AC charger by setting a voltmeter to 25 VAC. Touch the contacts with the probes. The transformer in the charger is bad if you get no reading at all.

Step 5
Check the contacts. These are metal strips or points located on the appliance and in the charging base. With the charger unplugged, wipe them with a cotton swab. Use a fine emery board to remove visible corrosion.
