A multimeter is your best friend

A perfect example occurred today of why you need to have a multimeter on hand! I had someone contact me with a column or switches out on his machine worrying that there was a major problem on the CPU. After a bit of time and careful guidance from me, it turns out that the problem was simply that there was a break in continuity from the board to the first switch in the column (could equally work with a row). Dont forget - always use your multimeter to check continuity before you dive in with board repairs. If you want any more advice, just email pinstig on pinballchat@hotmail.co.uk
