What to do if your radio has no power?
Radio, clock, power mirrors, and all 3 power outlets not working. Checked all fuses under dash and both compartments under hood-all are good. Checked for short with milliamp tester at battery-good also. Removed access panels around steering wheel and near under-dash fuse panel, looking for hidden fuses that may have blown-nothing.
Why are all my fuses working but no power?
Wiring between the underhood fuse block (PDC) and the JB could be broken or burned up. The #12 fuse location is central to the circuit, so finding out if power is present there will tell us which way to go. Here are the other circuits the fuse feeds… just in case one or two may still operate.
What kind of car radio wont power on?
I have a 2005 C320. The other day, I suddenly could not power on my radio. The screen is blank and the CD slot won’t take a CD either. It was working fine all along. All the other electrical items in the dashboard and everywhere else are working fine. This is the original radio that came with the car when i got it ( brand new).
What to do if your RAV4 Radio has no power?
There are 3 spare fuses 7.5 amp, 15 amp and another one can’t remember in the fuse box located on the engine passenger side to use as a test fuse. The test light allows not only checking the if the fuse is good but if it’s getting power. If not then you check further at relays etc. Sure, it’s a RAV4 base 4 cylinder 2wd. It’s not a JBL radio either.
How can I tell if my fuses are still working?
The #12 fuse location is central to the circuit, so finding out if power is present there will tell us which way to go. Here are the other circuits the fuse feeds… just in case one or two may still operate. Check a few of these other systems to see if they operate or if it’s isolated to the radio and dome lamps.
What’s the purpose of a 10 Amp Fuse?
Its purpose is to remove the slight electrical draws that some circuits have even with the key off, like radio (keeps time). Pull the holder up, then unlatch and flip the fuse cover over to gain access to the 10-amp fuse inside. Since it also powers the cigar lighter, this is probably where it met its fate.
Can a fuse have power on both sides?
You can have power on both sides of the fuse, yet not have it conduct power to the circuits if there’s a spread terminal contact on the circuit side of the connection (just had one on an Intrepid).
Why is my JB fuse not working properly?
It also shows a splice internal to the JB that splits power to the various places it serves, so with the entire M1 circuit deader-n-a-doornail, the problem appears to be within the JB itself. Pull that #12 fuse out to check the terminals for burning or damage.

What happens when a car radio fuse is blown?
In the case of your car radio fuse, it is designed to sacrifice itself to prevent a dangerous amount of current from flowing through your car radio and the associated circuit. If your radio is dead due to a botched jump start or charge, and you’re lucky, then you may find that your car radio fuse is blown.
What to do if your radio wont turn on?
Take some small gauge wire directly to the battery terminals, and connect to the correct pins on your radio harness/plug (yellow for power, black for ground). See if it even turns on with direct power. Rule out the HU itself first. EDIT, just read the above post.
Why does my car radio stop working after I Turn Off the battery?
There are a few different reasons for a car radio to stop working after the battery has gone completely dead. The first, and by far most common, is that the radio has an anti-theft “feature” that kicks in whenever battery power is removed.
What to do if your boat radio is not working?
Make sure you check the grounds too. Fuses are easy to check and a good place to start…but I’m going to bet a quarter that it’s a ground. If you have a vom or one of those lights for checking power…check the red power lead. If you have power going to the units…it’s a bad ground connection. DIDO ON BRIANS IDEA!
Why does my USB port have no power?
When you take it in, make sure you have a known good cord and device to demonstrate. They might try to say that a faulty cord or device with a short circuit caused the failure. Most USB power supplies (5VDC) are current limited to either 100mA or 500mA so that this is not an issue, just be prepared.
Can you use a reversed polarity USB outlet?
Yep, reversed polarity outlets will still power normal devices. Also don’t forget you might have reversed the polarity upstream of the new usb outlet that’s giving you problems….possibly the power out on the other outlet you installed if its on the same circuit.

Why is my USB port not working on my Toyota truck?
If you are certain the issue is with the truck USB power ( tried another device and another cord in it), fuses in the panel are all OK, then It sounds like time to visit your dealer for warranty repair. Thats why you paid the big $$$for your ’12 .

What should you do if your electrical outlet is not working?
A short circuit is dangerous and can lead to a fire. If the breaker flips again after you’ve reset it—and you don’t have anything plugged in—leave the breaker off and call an electrician. Loose connecting wires can cause an outlet to lose power.
What to do if your USB hub is not working?
1. Removed fuses #37 and #38 from the rear fuse box to kill all power to the uConnect system and USB hub. 2. Started the car and attempted to turn on the system. This should also discharge and capacitors that might be holding a charge. 3. Re-inserted the fuses to restore power. 4. Started the car and turned on uConnect.
Why is my USB hub not working on my Dodge Charger?
The rear seat USB ports charged each phone fine. 1. Removed fuses #37 and #38 from the rear fuse box to kill all power to the uConnect system and USB hub. 2.
