sound like dead battery.no power to fuses if battery dead use digital voltmeter check battery volts should 12.6 volts if not have battery charged tested.if battery 4 or 5 years old battery could be faulty.
see this causes and proceed . God bless you If the camera won't turn on, check the batteries, or connect the
camera to an AC adapter. If that doesn't work, remove all batteries,
disconnect the AC adapter, wait a minute, reinsert batteries and
reconnect the adapter.
If the flash doesn't work, the camera won't take pictures, or the screen keeps turning off, check that the batteries are strong.
Your camera can be defected. If you buy new batteries, and it still doesn't work, than you'll probably want to send it back to the manufacturer. First, call them and tell them your problem, and if that doesn't work, than you might want to carefully examine your camera, to check if everything is in the correct place, and their all working correctly.
Under the battery tray is a common ground point. It'll have several black wires going to a connector that is bolted to the frame. Remove this bolt, clean the area up, and bolt it back in place. If the speedometer doesn't work after this, then you probably need a vehicle speed sensor VSS.
Dear kimbroberg2 My husband and I did the exact same thing for our grandson when he was 8 months old. We pulled the car out of the attic last night and the battery did not work. My husband called the manufacturer customer service at 714-256-9888. He was told that the batter was too old and would have to purchase a new one. My husband called around for the item description that they suggested and found a comparable battery at Interstate Battery in our hometown. Good luck. I know we were very disappointed when this happened, but there is hope. Hope this helps.
then your alternator doesn't work, that's why it doesn't charge the battery.
If you wan't to know if this is the reason you can try this:
Start your engine, connect a multimeter on the propper battery terminals to test voltage level, with your car still on it must have around 13.5 to 14 volts. Turn on your lights and air conditioning it should not descend more than 13 volts. If it's less than 13 volts then your alternator doesn't work and it has to be changed.
Some people does this other test but is not recommendable:
Start your car remove ground terminal if the car remains on, then the alternator is ok (If you have a tester I would recommend the first method)
Disconnect the negative battery cable for 10 mins, then reconnect it and try. Sometimes it can lock out the Sirius unit, and by disconnecting the negative battery cable for 10 mins, clears out the whole system so it can be booted properly.
