I have very week spark at both cylinders
ok..it has been running excellent..starter bound last week on flywheel, nothing happened when I tried to start it, found problem while on the lake and fixed it. started right up. later that afternoon it wouldn't start. seemed flooded. plugs were soaked. changed plugs. no start. have since had it sputter start, run rough, stall,and now no start.put a spark tester in the plug wire, set it at 7/16..no spark, down to 1/4 no spark. I have very week spark if I put the plug in the wire and hold it to ground.new gas,plugs are wet now,I have no way of testing comp. I have disconnected yellow/black kill wire..no spark..hope this helps
where is the stator
ok, here is where it gets me nervous..can I do this in my driveway with limited ability..im reasonably mechanically inclined..not at all afraid to go for it..where can I get the puller..I am willing to buy tools needed..but will be limited to auto parts type stores
I am going to think it thru. im not fully convinced its the stator yet
Hi my name isXXXXX will assist you.
Why did you open another question? http://www.justanswer.com/boat/7vmk7-1986-johnson-50hp-cranks-won-t-start.html
I will ask you the same question do you have a ohm meter to do some testing of the ignition components?
I do not have a ohm meter. but will buy one..by the way..glad I finally am able to speak with you.. what a runaround that was..lol will I be able to figure out the ohm meter testing? ive never done it. but think with your help I can. I will be in and out from boat to computer. thanks
The wires you need to test are the brown and brown/yellow wires coming from the stator that connect to the power pack. Test brown to brown/yellow spec 450-550 ohms. Then test the brown to ground and the brown/yellow to ground. You should have an open circuit.
Post back with findings and questions.
ok. ill go get a ohm reader
ok I have a ohm meter and have disconnected the harness from the connector to the power pack. what do I set the meter on
am I testing from male to female at the connection. does it matter where yhe red or black tester lead goes. I need a little more instruction. I have never used a ohm meter
Every ohm meter is different and I have no idea what you have and can't teach you how to read a meter I know nothing about.
You are reading the wires coming from the stator under the flywheel. The brown and the brown/yellow it doesn't matter which lead connects to which wire. You want a reading of 450-550 ohms.
Post your readings.
I borrowed a neighbors meter....no instructions. 573 brown to brown/yellow ..do I need to change the setting to check to groung. when I checked it showed nothing on the meeter
With the black meter lead on ground check the brown and the brown/yellow with the red meter lead. The meter should not read anything.
you are correct. it shows nothing.
ok once I do this do I need to set the timing or anything before I can run it
No changing this part will not affect the timing just remove and replace and reassemble start and go.
do you have any idea what this part will cost roughly
Yes click here
thankyou I am thrilled to pay you for your help..couple more questions..how will I stop the flywheel from turning to grt the nut off, once I pull the flywheel ( im going to get a steering wheel puller now) is removal of the part simple, and how does the flywheel get put back on
do you know torque spec.
ok. can I pay you tomorrow..in case I have questions, I cant get the part till then..ill take it apart now
