Testing coin mech and credit boards

[elaverick]

Hi,
  I've just bought a box full of coin mechs and credit boards from eBay, which were listed as untested (amazingly I actually think these were untested rather than just broken ).  Problem my cab isn't far enough advanced for me to being installing things to test them.  It'd be really handy if I could run through them and see what's junk and what's going to be a goer.
Does any one have any advice for testing these things?

I;ve got a combination of Coin Controls C220's/Sentinels and Mars ME 111/ME 126's.

The 111's are a bit old but are worth selling on if they work, Same with the 126's but they are newer. The pins on the MEI validators are quite simple. There is a good website explaining them.

Ive also messed about with the Mars/MEI/Cashflow Validators as My cab has one and so does my fruit machine. Ive got some bumf on my desktop if you need any more info
