Cant find what im looking for

[fly4fish]

I hate bothering people with quiestions, But i am at a stand still. I have a 1978 (?) mercury 1400 outboard. I replaced all wires internal and external. new plugs and wires, new dist. cap. new stator. cleaned and went through all three carbs, rebuilt fuel pump. After all that, I went to start it and
no spark and no fuel in cylinders, I believe with no spark it could be a bad trigger or switch box. Right? But i am really flustered about the no fuel, i can over prime the bulb and fuel will drip from the carbs but as soon as i attempted to start it nothing fires. i pulled the plugs and noticed no fuel, the plugs were dry and thats when i tested for spark. Is there a way to test the trigger and switch box?

Thank you for any help, its greatly apprecitiated

Here's a simple test.

Dewey, Make sure the switchbox has +12V on the red and white wires on the switchbox's starboard side. The white wire runs from the ign key, and supplies +12V when key is in run or start position. Red wire is always hot.

Laddies test will tell you whether the dissy trigger is bad. Put an ohmmeter on the coil. The primary winding will have an ohm or two of resistance. it may read as a short. The secondary will have some ohms resistance. As long as the secondary is not open or a dead short, it is likely OK.
