Thread: onboard battery chargers

good day all! does any one know how to test an onboard battery charger? i have a 10/10 bass pro and no book. one bank makes the test light flash and the other dont do nuthin. there is a red a and a green light on one end and the green comes on when you plug it in. i guess the next step is to completely drain a good battery and see if it will charge .any body got any suggestions ,speak up!
thanks guys!

This info comes from an on board charger manual.
1. Disconnect the AC plug.
2. Disconnect the charger from both batteries and situate the leads so they will not short together.
3. Reconnect AC power and read the DC voltage across each set of leads. If the output is approximately 13.3VDC on both sets of leads then the charger is good and have your batteries tested.
4. If there is no output, check the fuses in each lead and replace as needed.
5. If the output voltage reads below 13VDC, then the charger is defective.

Hope that helps.

I was going to say to check your connections, But the reply above covers it all. Good luck. Also, some times if you disconnect your charger from the batteries and then re-connect it, it clears the charger and starts back working.Timk
