Hello my name is ***** ***** am I speaking with?

All Mercurys are cataloged by serial number, can I get that number please. This is just so I can see which engine you have, and which ignition system is on that engine.

Next, what is it you are looking to do? Are you looking to do step by step troubleshooting with a DVOM? Or did you want to know the steps we do in the shop so that you can try some of the easier stuff first before calling in the mechanic?
