How do I test this switch box...

[hi salenity]

I'm trying to test the Stator switch box and trigger . First off I don't have a DVA adaptor so I know I'm going to be a little limited on what I can test but I am not 100% clear on how to perform these tests. Do I unhook the wires from the switchbox or just test them at the conection terminals?

Like the Trigger if I leave it hooked up and test the Ohms between the Brown and White (trigger wires) I get an ohm reading of .684k and unhooked I get a reading of .810k (my meeter is autoranging)

This is a 1980 40hp

Always unhook the wires.

Re: How do I test this switch box...

If the wires are left hooked up while using a Ohm Meter your readings could be wrong. Always remove all the wires and test the componate by its self. This should be done for all testing using only Ohm meter if no DVA is used. The lowest reading that you get on the auto rangeing meter should be the one that needed. JMO

Oldman570 he has discovered it is indeed the switchbox He has replaced it with another and has some spark and is getting the replacement see post 40 HP key switch. Thanks for all the help as I tried my best as well. http://forums.iboats.com/mercury-mariner-outboards/1980-mercury-40-hp-key-switch-589738-2.html
