Given the number of times I've done that, I half-feel like mentioning a grandmother and sucking eggs ;-) More seriously, to draw out a useful schematic -- not just one that shows what is connected to what, but also groups related sections together, also requres a good understanding of the device, of what is likely to be going on, etc. In other words that brain comes in handy... -tony
