Hi,

While capping my Ms Pac board, I found a broken resistor. Its in spot C34, near CP11 and is bright green.

I cleaned it up, but cannot tell the browns from blacks. Can anyone help ID it?

The bands I got on the bright green resistor are either of these:

ORG or RED
RED RED
BLK BLK
GLD GLD
BLK BRW

I cannot tell and my manual does not list these parts...

I just want to be sure because years ago I put in some resistors on a board that were Ohms rated, but they really should have been Kohm, turned it on and got some sparks. Luckily just those components were fried.


Thanks,
 
Well that's whats weird is its labeled C and like you've stated, C is for a cap. I think now it also has a circle designation on the board, so that should have clued me in too.

What do you think I should do then put the correct CAP back in? My board cap kit did not come with a cap for it.
 
It's really not the sort of capacitor that fails with age. Depending on what circuit it's in, it might not even make a difference if it's there or not. I'm going to pull up the schematics and see what I can find as to what that cap does.

Found it on the schematic. It's 220pf, and it's a "deglitching" cap to ground off the output of the LS06 at 4F. Something tells me that it doesn't matter too much. But, since you've got the board on the bench already, might as well replace it. Any proper value ceramic disc cap (or even one that's close) will be fine.

Ok thanks for the info Ian!

I will replace it for sure, that's the way I roll.

One of the leads was cleanly broken at the board and the resistor itself and the machine played fine. I soldered a new lead to the resistor and it did not effect the game, thus like you feel, its obviously really not important.

Stop!

It's not a resistor. It's a capacitor! They do totally different things!
