Busted ac adaptor? can I fix it?

[nexus09]

Well since the world hates me, after spending a day trying to fix some networking/internet issues for a client I finally appear to be in the clear when the DSL router won't turn on. Now, I had just had it functioning not 10 minutes ago because I had spent hours trying to get into it w/o the password. My only thought is that I killed the adaptor to the router by accidentally plugging it into the wrong device (firewall).

Now, I'm obviously not that skilled with electrical systems, but I would assume that since the firewall is perfectly fine the ac adaptor would be as well. However as it is no longer delivering power to the router, it appears that something obviously happened.

My predicament is that I neither have a voltmeter nor an alternate ac adaptor, so I can't say definitively that the adaptor is busted. But as nothing has happened to the router since it was last working it seems the only conclusion.

The adaptor is outputting 16V ac, 1A. Is there any way I can fix it or simply create a new one with some parts from radioshack or something? Either way, this really sucks and I know the clients aren't going to be pleased that they won't have an internet connection for another few days :frown:

<edit>
I know this is technically a troubleshooting question, but there isn't really another forum where I can post electrical issues like this. If it turns out it's a problem with the router or something like that, I'll as a mod to move this to a different thread. thanks

Unlikely that you can fix it, and you can't make a new one. I'd also say it's unlikely that it died from being plugged into the firewall. Look at the firewall's power supply, see if it supplies significantly more than 1A. Post what the label says. It's possible that the firewall tried to draw more current though the adaptor than it wanted to give. That kind of thing usually won't kill it unless it's plugged in for a long time, though. If I were in a real crunch like you are, I'd find a way to test it. For example, find a case fan, strip the ends of the wires, and stick one into the plug, and touch the other one to the outside- pay careful attention to polarity and make sure your wires aren't frayed. You can find the polarity on the back of the router. Red wire is positive on the fan. If it starts up, it is giving some power, but not neccecarily enough for the router. If it's not giving any power at all, crack it open and see if there's a fuse inside- nothing to lose by breaking it at that point. If you replace the fuse, it will work until you can get a replacement. If it doesn't go back together nicely, keep it in a shoebox with an extension cord to keep anything from getting in there and shorting something out. Radio shack might have a generic one that will work- maybe.

Good luck.

Maybe try this one (in stock): 9-13 vac, 800mA

Or this one (not in stock, maybe local pickup): 18/24 vac, 1A

Thank you all very much for your replies. Fortunately I was able to get a replacement because the router is provided by the client's ISP so a quick call early the next morning and they had a replacement before noon.

Of course, this is only the beginning of my problems:disgust:, but this particular battle was won. Thanks again
