My tabletop juke box wont work know power at all

Hi, first, keep in mind a few things. When checking your power, you will want to check it with the light switch on. Next, do your high beems wrk? I would check your switch.

Starter or star soliniod. You need to check if you are getting power through soleniod and to starter.

The first thing to check is the tail lights. The cruise control will not work if any lights are out. Changing to LED tail lights also causes the cruise to not work.

(1) Make sure the wall outlet has power. (2)Make sure the power switch is "on" (3) check the fuses. If you discover a blown fuse, be sure to replace the fuse with the correct value. If it blows again, you may have a more serious problem.

Check for an injector fuse in the fuse box under hood. Pull off one injector connector and use a testlight to check for a steady power signal on one of the two wires, with key on. Should have power on one wire. If not, pull all injector connectors off and check again-a shorted injector can shut down the injector drive circuit-if power now, reconnect injectors one at a time. If one connection causes power to be lost, that is a shorted injector. Replace it. If still no power and fuse is good, you will need a wiring diagram to check injector drive circuit.
If you have voltage at the injectors with key on, move the test light ground lead to the battery positive post, and put the test light probe on the injector wire that did not light the test light. Now have a helper crank the engine over-you should have a blinking light on this ground circuit. If no light, or light is not blinking, the ground circuit between injector and computer is bad. See? Steady power is available to injector anytime key is on. When the computer internally grounds the injector circuit for a split-second, the injector is energized, causing the pulse.

u should have 2 fuses boxes 1 in the cab and 1 in the engine bay.

Check your fuses. This a common thing that can come up often if you have changed from stock stereo equipment to after market, or just because of old fuses.

Once you locate the fuse box, it should give you a diagram of which fuses go to the different lighting systems in your car. Replace them and the problem should be fixed.

If the problem is not fixed from that, then have your wiring checked throughout the truck.

some main fuse boxes are under the hood in a square black box, some autos hide them under the steering colume under the dash.

Check the unit for a fuse.

you most likely have blown a fuse.

look in the fuse box for DOME LIGHT. and replace,
can you elaborate what else is wrong with 4x4
