Battery Test
If your board suddenly quits working, it's not likely the battery pack. Worn out or defective batteries usually result in range reduction. As your batteries age, your range will gradually decrease, until the point is reached the range is unacceptable, and they will need to be replaced. An immediate and severe drop in range can be attributed to a defective battery charger, or a defective battery (the battery pack is built with four separate 12 volt batteries). If the powerboard has not been used for some time, and the batteries have not been kept charged, it is very possible that the battery is the issue.
| 1. The easiest test is to check the battery voltage at the charger connector port with your voltmeter. |  click to enlarge |
| 2. With the voltmeter set to "DC", insert the red voltmeter lead into the battery port number marked "1", and the black voltmeter lead into the battery port marked "2". You should get a reading of between 24 and 27 volts. Be sure the battery pack is fully charged before you perform this test. Additionally, turn your remote gun on and run your motor full speed, observing the voltage at the same time. If there is a drop within 30 seconds of .75 or more, there is problem with the batteries. |

| 3. If there is no reading at the charger port, although rare, the charger port or it's wire leads could be defective. A second test should be performed at the battery leads where they plug into the pc board. a. Remove the fin plate bolts completely before lifting the plate up. b. Remove the red battery lead from the pc board marked red +. c. Remove the black battery lead from the pc board marked black-. |

| 4. Insert the red voltmeter lead into the red battery lead, black voltmeter lead into the black battery lead. |  click to enlarge |
| The voltmeter should read between 24 and 27 volts. If there is no reading, the batteries are completely dead, or there is a problem with wiring in the battery pack (very rare). | |
