What if you don't gound the clock wire

[Fixit]

Charlie,

Lets talk some more about the massiah2 clock(36MHz) wire. I have in stalled a massiah2 in a V4 PS2. Working fine.
However there are very faint lines diagonally, many when the laser is reading. It was worse (not faint) so i thought of changing the power wires, did use 30awg kynar, then doubled up. I was using the same wire x1 for the clock, Which i changed to stranded wire.
When i tested the ps2 i noticed that there was a very big improvement, but not gone, the lines are still there very faint.

The person i chipped it for hasn't even noticed.
But I'm a perfectionist.

If i ground the clk wire would that be it.
What problems have you noticed when the clk is not ground?

I have install few messiah1s this problem is not there. I did use i different wire to in stall M1s. That's what i put it down to.

Reading the posts you mentioned grounding the clk. I think that could be my problem.

any ideas?


thanx pal

Yes - what you describe is a ditinctly possible effect of the CLK wire traversing an IC or a video line. Wrapping a grounded wire around the CLK would remove this possibility.

Thanks Charlie.

I have no ps2 to chip at the moment.

As the messiah2 has this extra wire (clk) than messiah1, which did not suffer from this symptom. It could be the culprit.

thanx pal, i will let you know.
