N64; help needed.

[Bandrien]

For some reason when i connect my screen and n64 mobo to the batteries (7.4v 6600mah)the n64 ( works with no screen connected ) shuts off when the screen is connected.
Any ideas?

It sounds like something isn't getting enough current to it. What kind of wires or switches are you using? (what size?) Using bigger wire might do it.

Sounds to me like yer batteris cant handle the total load of the screen and console. Can you run just the screen off the batteries without the n64?

If those are the specs of his batteries then they should be plenty to run it.

Also, if the battery isn't charged enough, then it won't be able to output the voltage it says. Try charging the battery too. Someone on here a few days ago had the same problem and just charged that battery and it worked fine.

But the specs arent the same when its all under load. the power likely drops below the 7.4v especially if he hsant charged them recently.

Even so, your battery would never drop a whole volt. My n64 is using a 7.4 volt battery, and it can go down to 6.8 without any problems. I'm sure they wouldn't rate the battery at 7.4 volt if it dropped very much voltage under load.

A cheapo chinese company most certainly would. All of this can be easily answered if the OP has a multimeter.

I don't think that there's as many fake batteries as people think. But yeah, he just has to charge it, then measure it, then measure it under load. Nothing is as good as stright up testing.

I read somewhere in one of Bacterias threads that he found quite a few falsely labeled batteris. Im pretty shure their more common than you think.

The false batteries I got were for the NDS Lite. They were quoted at 2 amps, yet seemed more like 0.8 amps. Not had an issue with camcorder cells so far.

Issue mentioned that the N64 works until screen is connected means the batteries are having issue with draw - perhaps they need recharge. The other thing it can be is that you aren't using decent wire to connect from battery > TI card > N64 - you need to use decent wire, like 3 amp wire.

i hate it when batteries are falsely labeled. my first set of batteries were labeled "7.4 volt", but when i charged them for 10 hours i could only get 6.501 volts.

The first time I wired camcorder batteries I actually wired them wrong. It still charged but extremely slowly. I put both leads of the charger into the positive of the battery. Remember to quadruple check your connections. And thank goodness for protection circuits.

ok well I fixed the problem(the cart slot relocation had a solder joint from one pin to the outer ones connection to the metal outer coating on the expansion slot)
but now I have a new one:
I restarted on another n64 i had laying around and relocated the cart slot,but when i hooked the n64 up to test on a psone screen(the screen was running off of my batteries and the n64 off of the original power supply)the screen wouldn't turn on......................
the n64 is working fine, so do you think that 6600mah is to much or something because it was working fine when they were both running off of the batteries
Im kinda a noob so sorry if this is a stupid question

Do you have your positive and ground wires mixed up? And you can't ever have TOO much mah. Are your batteries charged? They may not have enough charge left in them to turn the screen on. And your really only making yourself look more stupideder by saying Im kinda a noob so sorry if this is a stupid question.
