The Stovebolt Site Forums The Shop Area Engine Shop points

Recently I needed to check my dwell and can never remember where to hook up the meter, since I only do this about once a year. I did a search here and found nothing. Checked other sites I have known and still no result. The specs are easy to find, but where does the meter hook up? Finally found a Porsche site that instructed to hook to coil neg and ground. This is one of those stupid things that a lot of poeple take for granted until they can't remember. Can we post it in a tech forum for all?
