N64 Aussie Power Supply

Hey guys,
I got a nintendo 64 off my friend the other day and it wouldn't power on but l did manage to borrow another friends power supply and it worked so l'm wondering if its possible to fix the current one l have?
I cannot see any signs of a blown power supply and unfortunately l don't have a multi metre. Is there anything you guys can suggest or am l just better off to go and buy a replacement n64 psu?

 

First thing would be to check that fuse on the left hand side... but you don't have a multi-meter to do so. You can literally get one for a few (US) dollars on eBay:

If you're an electrical engineer you'll want something better, but for just the odd hobby job, it does the trick.

 

alright thanks mate. l just bought one off ebay then. l had no idea they were that cheap haha
well l guess l'll have to wait now till May before l can test this haha

 

Could've also just gotten one from Supercheap.

 

those $3 MM's are absolutely usless

 

I read that as $3 M&Ms. I must be tired.

 

I would say it might be best to acquire another power supply that matches the mains voltage in your country - preferably Nintendo branded. To diagnose a switch mode power supply (smps), an o'scope for waveform analysis is more appropriate than a MM. Do keep some things in mind when messing with this N64 power supply on a non-conductive work surface:

-Ground/negative reference is the large heatsink below transformer
-Do not touch the top of the large capacitor or the adjacent smaller heatsink with hands (either would read in the ballpark of 80V pulsating DC or even AC) it can zap even after unplugged
-check 120/240V mains fuse
-check the 3.3V and 12V fuses, located to right side of transformer (below connector to N64)

 

I have to disagree. I've used that exact same one and never had issues... worked fine for voltage and checking continuity. Maybe you got a bad one?

Again, if you're an electrical engineer, you'll want something better. But for odd hobby jobs, it does the trick.

 

the one I used, it was a fancy $5 one! Was waaayyy out, it read 12v as 22

 

Would like to find a fix for these I have a stack pile of psu like these all fuses are checked.
