6hp Evinrude --- No Spark

[Cornbread9]

Motor isn't starting. It is a 1998. I tested for spark with an inline tester. No spark on either plug. So what next?

Re: 6hp Evinrude --- No Spark

check to see if you are getting power to the coil

Re: 6hp Evinrude --- No Spark

You can test the sensor and magneto coil with an ohmmeter -- the specs are in the service manual.
If they are OK, suspect the power pack, which has active electronics in it.

Re: 6hp Evinrude --- No Spark

also check the kill switch circuit.

Re: 6hp Evinrude --- No Spark

I have taken the coil off. I know to ohm it. I have some questions? Where do I ohm it? What results should I see? If it is bad what results will I see? These are the results I normally get. Note: The coil has some cracks in it, but I would like to test its functionality so I know that it is the problem before testing the power pack. Which will be my next post question. I will try to upload the picture of coil. Thanks for any help.

Have you disconnected the black/yellow wire from the power pack ??

Go to cdielectronics.com. They have good trouble shooting procedures.

Re: 6hp Evinrude --- No Spark

The kill switch: I did ohm it out. It did not ring out. When i pull the lanyard out, it rings out. It seems normal as long as it is normally open. Thanks for the website. It seems like a logical step by step guide. I am not familiar enough with my motor and jargon to follow it. I don't have an evinrude 6 hp manual. I was hoping to avoid getting it but I think it will make things easier. I just know it is the coil or the powerpack and I don't know how to tell which.

Here is the Service Manual $19.95 delivered. Save yourself some torture in all aspects of your motor.

Swapped coil with eBay replacement, used. No spark. Tested stator wires while pull starting, and have voltage to powerpack. I guess I will replace pack and let you know.

 

[Cornbread9]

Replaced the power pack with a new CDI pack and no spark on either cylinder. I should have bought the manual. So I am working back to the stator. There are 4 wires coming from it. Two from one side, two from the other. 2 ring out, the other 2 do not. This is a manual start 6hp Evinrude 2 stroke. I wasn't sure if all four were supposed to ring out. Also was trying to test the shift switch, but don't see and wires near the shifter like the kill switch. After typing this, I think I had better get the manual. Any input would be appreciated though.

Go to cdielectronics.com. They have good trouble shooting procedures.

While awaiting a Factory service manual, listen to boobie...it's free- so that should fit into the budget...

 

[racerone]

What does----" ring out "----- mean ?

 

[Cornbread9]

I ohmed black/white to white/black - timer base - 37 ohms. From a general 2 stroke guide - that was within range
​I ohmed brown to brown/yellow - I guess this is the stator coil, and got .817 KOhms or 817 ohms which is higher than 500 ohms on general 2 stroke guide.
​The second one is supposed to be brown to engine ground, those are the only two other wires so I assumed brown/yellow is ground. When I ohm brown to the block I get infinite resistance. Since they both showed a resistance in the first tests, I thought that if I set the ohm meter to the audible setting, they both would ring/beep, and they didn't. I'm trying to do the Dva tests on the stator. I guess I need another multimeter attachment?

 

[Cornbread9]

Multimeter doesn't make an audible noise over 40 ohms. So that explains that. Dva adaptor and manual it is. Strange thing is, the motor looks like new. It had only been used a few times when my brother sank the boat. It started and ran a minute after sitting a long while. Then it had no spark. It looks like new but has about 10,000 pulls on the string.

 

[oldboat1]

Sooo...the shorting circuit shows full continuity with the clip out -- no continuity with the clip inserted?

If the kill circuit is not completely open with the clip inserted, the engine will not start. I would disconnect the switch and try again (or test for spark).

If that motor went in the lake at some point, was it serviced immediately?

 

[Cornbread9]

I have taken the kill switch out completely for testing. Wires are capped off. Boat took on water while the motor was running and he raced back submerged. I don't think he serviced it immediately. I did get it running in a container and then it lost spark all at once. It had a strong spark before it crapped out. None of the Lowe's, advance autos, or electrical stores had a dva adaptor for testing peak voltage. I am going to have to order online. I don't know of any test to run. I have been going by this trouble guide.

No Fire at All: Disconnect the black yellow kill wire and retest. If the engines now has fire, the kill circuit has a fault-possibly the keyswitch, harness or shift switch. Check the stator resistance. You should read approximately 500 ohms from the brown wire to engine ground. (See DVA Charts). Check the DVA output from the stator. You should have a reading of at least 150V or more from the brown wire to brown/yellow (while connected to the pack). Check the timer bases resistance from the black/white wire to the white/black wire. Reading should be 10-20 ohms or 38-42 ohms. Check the DVA output from the timer base. A reading of at least 0.5V or more from the black/white wire to the white/black (while connected to the pack) is needed to fire the pack. Check the cranking RPM. A cranking speed of less than 250-RPM will not allow the system to fire properly. Check the DVA output on the orange wires from the power pack while connected to the ignition coils. You should have a reading of at least 150V or more. If the readings are low, disconnect the orange wires from the ignition coils and reconnect them to load resistors. Retest. If the reading is now good, the ignition coil are likely bad. A continued low reading indicates a bad power pack.
