OK guys, First I am new to this site and have found it ver helpful. I hope you all jump in and get me straightened out on this one as well.

I have a 1988 45HP that has sat for about 6 years, I have already cleaned out the carbs and relpaced all the fuel lines. New batteries and tried to start her up today and she cranks great. But that is where we stop. I have checked the KILL switch circuit. I disconnected the black and yellow wire at the engine and it did not make a difference. While cranking the engine over I took some voltage readings on the switch box and it reads around 14.5 to 17.5 VDC on the input wires. If I trip the kill switch the voltage drops for these connections. I checked the plugs and they do not have any spark when shorted to ground. I need to know where to go from here. I donot want to drop $200.00 for a new switch box unless the consenus is that that is my problem. Any help would be great!

Thanks

Re: new old mercury owner needs HELP!!!

If you are not using a DVA when you test for voltage you will get a false reading either you don't have a DVA in your meter or the stator is bad as you should have 180+ volts on the Blue/ Blue White and 25+ volts on the Red/Red white wires and 4+ volts on the 4 trigger wires. If you don't have a DVA we can give OHM readings but they are not as accurate

OK, I do not have the DVA meter adapter so I tried to take some ohms readings per the manual for this engine. Here is what I got. for the stator on the Blue to Blue/White wire with them disconected from the swithc box I got a 6.74K ohms resistance. This is within the limits of the manual, But for the Red to Red/White wires I got 157.0 ohms The manual says reading should be in the 50's only. If this is correct? Am I right in thinking this is my problem? (Bad Stator) The Blue/WHite wire to ground checked open and so did the Red/white to ground. any help would be greatly appriciated.
