Hi all i'm new to the site and sorry my 1st post is a problem.
I have a 1979 mercury 402 40hp and when i dug it out the shed i put some fuel in it and it fired straight up (it had been sat a few years). i order new impeller and new plugs and installed them and everything seemed ok. I then tried to start it again but nothing. i sometimes have a very weak spark and sometimes nothing at all. I'm trying to do some test on the outputs but i dont have a manual to refer to and am having trouble locating on the internet.
I read somewhere that i should be seeing 180v coming from my stator. I have 4 wires coming from my stator, a red a blue and 2 yellows. I have 0.5v from the red, 7.0v from the blue and 1.7v coming from the yellow wires.
I dont have a DVA just a multimeter but i also read that you can read the values in AC the multiply the reading by 1.41 to give DVA readings.
Any help would be appreciated.
Regards
Nathan
