•
Halogen lamp (500W or greater) or be outdoors in the daylight.
•
Voltage meter
•
Amp clamp or Ammeter
1. Attach voltmeter on the battery and measure the voltage.
•
Voltage must be less than 12.8V for the solar panel controller to turn on.
•
If battery voltage is not less than 12.8V, then put a 12V load on the battery.
Figure 14. Measure battery voltage.

2. Move vehicle outdoors into the daylight. If indoors, put at least a 500W halogen lamp
approximately 24'' above the solar panel and turn lamp on.

e:: The solar panel controller may take up to a minute to turn on. The solar panel must be
connected to the battery in order to turn on the charge controller.
3. Attach voltmeter on the battery and measure the voltage.
a. Voltage reading should begin increasing or stay the same.
4. Place amp clamp around the positive cable from the solar panel.
a. Amperage reading should be greater then 300 mA
