Mercury 40 NO fire?

[streamyTN]

Is there a troubleshooting method for a 40hp, Mercury. It's a 1978 402 model 40 HP <br />2 cylinder S/N 5042254. <br />The problem is no fire to plugs! <br />I've been told it's either the power pack <br />#3324911 or the individual coils. <br />Is there a way to test the power pack? <br />Say with a multimeter.<br />Check voltage out on each of the wires?<br />Then test the coils? <br />Thanks <br />Steve

If there is no fire at both coils it's likely the powerpack is the route of the problem.<br /><br />TMD

You will also have a mercury tilt switch that needs to be ruled out.Just ditch it if it is found faulty.

Hello,<br /><br />I have the same Problem. I changed the switchbox and no success. From my dealer I got the Info, that at my Merc 402 the Trigger Plate or the Stator is faulty. Unfortunalety it is the most expencive Spare part.<br /><br />Thomas

Mate from Germany: Did the dealer have any tests for you to determine if the stator was the issue?
