QUESTIONS & ANSWERS
Ask a Question-
My unit is plugged in through a lighter outlet on a boat. I don't get any led lights with it plugged in or not plugged in. Is it dead?
If there are no Red LED light whether the charger is plugged in or unplugged, the issue could be related to either the cigarette lighter socket or the battery. Let's do a few quick checks:
- Check the cigarette lighter socket. On many boats, the socket is only powered when the battery switch or ignition is turned on. You can verify the socket has power by plugging in another 12V accessory or testing it with a multimeter.
- Connect the charger directly to the battery using the included battery clamps. If the LED light starts to blink red when connected directly, then the cigarette lighter socket or its fuse is likely the problem.
- Measure the battery voltage. If the battery os complete dead, the charger may not be able to detect the battery, so the LEDs will remain blinking green.
Please let me know:
- What is the battery voltage?
- Does the LED light blinks red when connected directly to the battery with the clamps?
With this information, I'll be happy to help determine whether the charger or the boat's electrical system is causing the issue.
