Drawing schematic

[Skeleton Man]

I'm trying to hand draw a copy of the wiring diagram from inside the coin door of my machine. It's covered in mould and grime and is falling to peices, but I can make out some details.

My problem is I'm hopeless at drawing and I can't get anything to look right..

I tried photographing the diagram, all you see is a brown and yellow patch with lines on it !  Get any closer and all you get the reflection from the camera flash..

Does anyone have any suggestions ?  I suppose I could draw up something based on the physical wiring, but it's confusing because the wiring diagram shows sold out lights, and the machine only has back lights for the buttons !

If anyone knows where I can find a schematic for my old cornelius square-top that would be even better.. but I'm doubtful... nobody appears to have even heard of my model !

Get a trouble light and hold it (or have the gf hold it - the light that is) off at an angle and turn the flash off.

Last resort will be to carefully steam the remaining pieces off and reassemble on a copier or scanner and then try and connect the paths. Long shot but really have no other option that I can think of.
Best of luck!!

Update: I've managed to draw part of the relay/coinmech wiring.. need to look at the wiring harness to get the rest I think..

Question: What do you call the microswitches that tell the coin mech the machine is vending ? (ie. control the crems)

[johnieG]

It's sometimes refered to the "Vending"  switch, it normally is held closed ( it puts a 115 volt AC signal on pin #7 on the jones plug) to tell the coinmech/CREMS that it's ready to "vend" , then during a vending cycle, it opens, (on some coinmechs this is also refered to as the "Blocker" line)  ie: it blocks the coinmech from accepting coinage until the vending cycle is completed (you pushing the selection button, or pulling a bottle from the stack.)

I thought it was pin 6 ? (pin 6 is CREM, pin 7 is VEND NC)

I just needed the name for my diagram.. wasn't sure what to call those switches..  thanks '>

I'm making progress with the diagram.. nearly got the vend mechanism drawn up.. (well scribbbled on scrap paper.. still gotta draw it up properly in Visio)
