If your Ram 1500 is experiencing electrical problems, you should always check the fuses first, because they are relatively easy to check and cheap to change. Electrical components such as your map light, radio, heated seats, high beams, power windows, headlights, fan blower, defroster, door lock, power seat, windshield wiper motor, fuel pump, horn, anti-lock brakes and rear view camera all have fuses and if they suddenly stop working, chances are you have a fuse that has blown out. And you should try to use a fuse that is not critical to the operation of the vehicle in case the tap comes out or becomes defective.This video shows how to replace blown fuses in the interior 2007 Dodge Ram 1500 fuse box of your in addition to the fuse panel diagram location. Not all fuse locations may have the room to accommodate these taps. Be aware that you may need to turn on the ACC or IGN before you read 12 VDC on specific fuses. The voltmeter's positive lead is the probe, clamp the voltmeter's negative lead to any chassis ground. To determine which side of the fuse socket is live, remove the fuse and then use your voltmeter probe to test each side for 12 VDC. If you're tapping into a normal Micro2 Fuse socket, always align the Fuse Tap's 12 V Line Input prong with the 12 V live side of the fuse socket.
If the instructions that come with the tap are not clear about this, and they're often not, you'll need a VOM meter to see which side of the fuse the power is coming from and match it correctly to the proper terminal of the tap. If you plug it in backward, the OEM fuse location will still work properly, but the tap will not provide fused protection to the new accessory. You would not want to swap the two.Īlso, keep in mind that these taps can only be plugged-in in one direction. Be very careful not to confuse the two sockets, especially if you're using say a 5 amp fuse for the new accessory and the OEM fuse is say 20 amps.
These taps may be wired differently so carefully check the instructions that come with it, but usually, the upper fuse socket is for the new fuse while the lower socket is for the OEM fuse.
If the accessory fuse blows, you won't lose power to the OEM circuit and vice versa. Both fuses operate totally independently of each other. One is for the existing OEM fuse and the second is for the added-on accessory.
Basically, they allow you to tap 12VDC power from an existing fuse location and send it to an added-on accessory. Click to expand.Like said above, you use a Micro2 Fuse Tap.Ī lot of people don't know how these work as they can be confusing.
