3.45V alt on v7?

[Headly]

Are there any other alternates for the power wire on a version 7 motherboard for a messiah install. I know of the main one and the alt that are stated in the install diagram. I also know that I could use the 3.45V for the color fix, but I would like to leave this open for the fix. I am trying to change my magic chip to a messiah and the first two power spots just aren't working. I had gotten them to stick just a little but the wire pulled off. Tried soldering again and the connection gets worse and worse. Please help, thank you.

use 30awg kynar for the power u should have np then

i shouldnt post that here but messiah2 runs on such low voltage it will cause np

flux the resistor ,put blob of solder paste on wire,bring wire to the resistor,touch solder paste with solder iron,should work does here even with thicker wire

Managed to find some kynar wire. Looks good. More easily stripped then enameled and stay in the position you put it better too. Just out of curiosity, what do you use to strip your wire. I have been using a set of nail clippers. That was a real pain with the enameled wire.

Another question also. I have two different messiah chips, some from you and Charlie_PS2, and one That I overpaid for from another place. The one from the other place is version 1.08, yours are 1.22. Whats the difference?

I myself haven't tried this one, but I should work.

Just out of curiosity, what do you use to strip your wire.

When I installed mine, I used a lighter. Headed up the end of the wire and with a paper towel pulled off the melted shielding before it hardened again.

Thanks for the alternate points kooldraco. Unfortunatly it was no help. I have tried 2 SCex points in combination with three 3.45volt points and it still will not work. I did get the power wire on the original point. I had to buy some new flux and just load the point with it, and it eventually took. Pisses me off! I had been waiting for a DMS3 but heard they had this problem, then that problem, and another problem that their working on, so I said F it, I'll just throw a messiah in there. Now after two days I've gotten no where. So now to go pull out all the wires and start over again after work on wednesday.

Stripping wires....i my self used a razer blade. I layed the wire flat on a cd case. Then rested the razer on it, in a chopping position. Then with my left finger, rolled the wire, and the razer about an inch. Then pulled the cut plastic off.
Too much force with razer will cut it off. But after about 5 wires...i had it down good.

If you had 2 needels, same size as wire. You could put them on both sides of wire while you cut with blade...as a safety for the wire. (i have non myself...)

wire stripers

the kind with a spring and wheel adjustment once set corret just lock the wheel off

v1.22 covers more versions of ps2 and uses a better code

I was pretty sure that one would work, sorry about that.

I found the odd problem with using AWG30 kynar wire for the 3.45 connection ( thread marked 'suspect Messiah 2' being one of them.

Occasionally I reassemble and find that the messiah 2 seems 2 be dead.

Have now started to use thin multi strand wire for the 3.45v connection and ground as this is easy to tin and still small enough to get on the 3.45v solder point and haven't had a problem since. Also use stacks of liquid flux on point and adjust solder Iron up another 25 degrees if having trouble getting wire to take.

As for stripping wire, used to use my old chunky soldering iron to melt the insulation back but now use thermal strippers. super quick and perfect every time.

OK, I just tried the install for the third time, still no luck. I have tried 24 and 30 gauge for the power and ground. Tried 3 power spots, 2 ground spots, and 2 scex spots, and 2 messiah chips. All solder points have looked excellent each time, all wires are hooked up to the correct places, and it still acts as if there is no chip. WTF?

[ottoman]

The only thing I can suggest is to use slightly thicker multistranded wire for the power and ground, Then flash up the PS2 in bits i.e just motherboard, power supply board and dvd drive on an insulated surface and get a multimeter across the 3.45 volt and ground connections on the messiah 2 and check that the voltage is actually getting there.

It's a bit tricky getting it plugged up together without a shield around the board or a case but can be done ( I've done it).

You'll need lots of none conductive stuff to prop things on, U should just need motherboard, power board, DVD Drive and reset/eject button assembly.

Good luck.

I have noticed that the number on the board is GH-022. Where would I find the BIOS numbers? I have looked on the chip but can't seem to find anything that matches the three digit format used.

[ottoman]

Ah, u thinkin that it the diode problem?

I think the number u after is the bottom right hand number on the chip, 0***.

Wot version messiah 2 is it?

If it recent then should be 1.22 or 1.3 and they should be okay.
