I have a 95 Accord LX 2.7, AT with 160,000 miles. We have had it for about a month now, it did not come with a radio installed. when we purchased it, the OBDII did not work, and I traced it to the fuse box under the hood, replace the 20amp and 7.5 amp fuse. now every time my son tries to plug in his cell phone charger, it blows the 20 amp fuse? Any ideas??

 

If the fuse blows only when the charger is attached, then the charger may have a fault. If the fuse blows as soon as switch is turned to On, then short to ground must be found. First inspect the charger socket (see below), then if no short found, wiring will have to be traced w/ a fault trace tool to locate the damaged position in wire.

Look for a short in the cigarette lighter socket. Check for coin or other metal inside the socket. If nothing, remove and inspect the assy for damage.

good luck

 

Thanks for the reply, I know that the charger isn't the issue. I can use it in any of my other vehicles with no issue. it only blows the fuse when power is discharged. When we change the blown fuse, it is fine, plug in the charger, still fine, attach phone and it blows out again. I crawled under the driver side dash and noticed a very shotty wire job in an attempt to install an alarm. Who knows what they did prior to me getting this vehicle. wondering if getting a new harness and just running it new would be better?

 

What you are telling me is illogical. No draw until charger is loaded w/ phone and fuse blows. Sounds like load caused by phone is exceeding fuse capacity, unless there is additional load on the fuse (other circuits). You need a wiring diagram.

good luck

 

Ok? I put a new fuse in and turned on the vehicle, no problem. OBDII port and dash clock worked. Pushed in the cigarette lighter and pop, fuse blew.

 

The cigarette lighter is an open circuit until the lighter is pushed in or an accessory is connected, such as a phone. You have a short to ground somewhere in the circuit, that's why the fuse is blowing...Like Texas said, you need a diagram to chase down the short, as well as at least a test lamp and multi-meter.

 

Thank you, just pick up a Chilton manual, hopefully I will be able follow the diagram in it. Thanks again!

 

If the wiring was shorted before the lighter socket, the fuse would blow immediately when you turned the key on. My guess is the lighter socket is the issue, or plugging something into the socket is moving the wiring enough to short it. Take a look at the wiring behind the socket for any obvious damage or evidence of arching.

 

You were 100% correct!! Bought a replacement lighter, took out the old one and several pieces of metal fell out of it. Put in the new one and it works like a charm. Thank you for your input!!
