i just purchased a used mercury 115 it is actually a tracker by mercury marine

it is a 2004 and i watched it run when i picked it up. i put it on the boat and fired it up 2 weeks ago ran it for a minute

since then i ripped all the wires out of my boat and replaced all the bad grounds etc.. i basically just fixed the livewell pumps and things of that sort.

somehow i have no spark to the sparkplugs before i ripped the stuff out of the boat it ran i then hooked up the temp guage to the temp wire and that is the only thing on the motor that i touched.

however i unplugged the temp guage and still nothing

motor turns over fine it just does not fire im so confused. i guess it could be something to do with the controls but i dont understand what?

the only thing i touched in the boat that is related to the new motor is the controls because i spliced a trim wire to run it to the front of the boat so i could have that trim switch up by the foot pedastal

however i dont see how that would conflict with anything that has to do with spark on the motor

please respond with any sugguestions. i checked the fuse that is on the top of the motor and thats fine and i dont see any other fuses

confusing post :-/  try your killswitch

Sounds like the killswitch to me also
