Leave 'em, there not needed.

Anyone have any ideas? I've re-wired that cart slot again. I made sure that the white arrows on the cart & motherboard were facing each other & used daguuy's picture for wiring? I'm still getting the same results, however - no video. I think that the real killer is that it takes so long in between knowing if it is going to work or not.

Thakns.

Edit: Even better My red led started out on, but then went out after about 5 seconds....

did you try checking for shorts and stuff?

looks like it's wired up correctly....

um....check to make sure the dc-dc converter is still outputing 3.3V....check to make sure the video line isn't shorted or anything....

try shortening your wires by a lot...

they go to the right holes.

I don't think the voltage drop from the wires' resistances are significant - my wires were about that long on my portable.

Check for shorts. Get a magnifying glass if you must. But know that even one fleck of solder in between pins will foul things up.

Make sure you have the jumper/expansion pak in the correct way as well.

For the power issue, check all your power inputs with a multimeter. Maybe somthing went bad. Make sure all the ground points meet at the N64, and are good connections.

For the cartridge slot try just melting all the places on the board again. You never know when you can get a cold solder, and reheating it can fix it.

im not worried about impedance, im thinking more about interference. especially since his wires are all tangled like that. not tangled. but you know. all over the place.

all you can do really Is check your wiring. Make shure your inputs are outputting the correct voltage. make shure they are correct while the system is on, so that the voltage drop isint killing you, a weak battery. Check to make shure the A/v Out plug is wired properly. Make shure the cartrige pins all line up, and last, make shure that everything is plugged in.

Ok,

It seems like I need to do a couple of things. Here is my plan.

1) go to the shack to get a multimeter,
2) Desolder everything (the cart connector & the board)
3) Solder againg using shorter wires.
4) trouble-shoot with multimeter (I may need help with this step)

This will probably take me several days, so that I can be as carefull as possible with soldering.

In the unfortunate event that I still have no luck, would anyone be willing to help me trouble-shoot the connections if I provide shipping back & forth?

Thanks again.

First, before you desolder everything, use the multimeter to check (turn it to Ohms)
You may end up finding a tiny fleck of solder, and save yourself a good bit of time.

If you can't figure the thing out I'd be willing to check it for you (and get it working also.)

also, remember that unfortunately, you're N64 MIGHT have broken....make sure you go through all the right steps when testing it...

1. turn it on, with no expansion pack in and no cart. in.
2. plug in the expansion pack while it's off and turn it on for 10 seconds or so.
3. plug in the cart. and try it. try reinserting it a couple times if it doesn't work right away....I usually do

.

and as marshall said, check for shorts before desoldering and rewiring, and if you can't find any shorts, then it might just be something wrong with the N64.

as for the length of those wires...well, they ARE a bit long, but I doubt the interference would mess with the data much....I've used wires about 3/5 that long and had no problems (well, no interference problems

)
