How to Troubleshoot a Jensen Marine Stereo

Corrosion plays a big part in premature failure of all electronics equipment.

Jensen marine stereo entertainment systems look a little like a car stereo head, but they have greater tolerances for water penetration, vibration and have to be louder, too, to be heard over the sounds of the engine and water. A marine environment is also a lot more punishing in that corrosion plays a big part in premature failure of all electronics equipment. Consequently, Jensen marine stereos need special care if they get wet. Problems with a Jensen marine stereo can be related to skipping, power, condensation and other issues.

Instructions

1. Check that the installation angle is less than 30 degrees if the CD's skip. Thirty degrees is the maximum angle the equipment should be installed at to avoid water penetration in the CD slot, too. Other causes of skipping can be rough waters. Use the radio side of the equipment for entertainment in that case.

2. Turn the vessel's ignition key to the "ACC" position if the Jensen marine stereo won't illuminate and play. For battery saving reasons, the devices are wired so that it's difficult for them to drain the battery if they inadvertently get left on. Check the fuse in the red wire, too. Sometimes a storage facility will remove the fuse to stop the presets, clock and other always-running elements in the stereo from draining the battery while in storage.

3. Let the Jensen dry out if there's visible condensation on it. Try not to let it get wet in the first place --- the devices are water resistant, not waterproof. Be careful if you try to waterproof the equipment with aftermarket gear. The Jensen can overheat if you block the vents.
