No spark Evinrude Ocean PRO 150 98`

[Andrik]

I have lost the ignition on my Ocean Pro 150 98`. I am not very good at electronics, but have done some testing with an ordinary multimeter. I have done as follows;

1. Stop Circuit test. Separated the 5-pin connector between the stator and the powerpack. Still no ignition.
2. Testing the grounding on the 5-pin connector between the stator and the powerpack. Black meter lead to ground, red meter lead to orange and orange/black. No voltage registered when cranking the engine. (Switched both to 100V and 500V )
3. Output test on the 5-pin connector between the stator and the powerpack. Black meter lead to orange stator lead, red meter lead to orange/black stator lead. No Voltage. (Switched both to 100V and 500V )
4. I have also tested the resistance on the stator. It shows 0.3, exactly the same as the stator that works on my other Ocean Pro 175

Have I done anything wrong, or will an ordinary multimeter not work on the output testing?
Does anyone have suggestions for further testing?

The cdielectronics web site has a step-by-step troubleshooting procedure for your ignition. Most tests can be done with a multimeter and a DVA.

Thanks. Looks like a good site. Seems that I need a peak reading meter or a DVA. I will try to make a DVA or borrow.

You are on the right path, Your very smart to keep testing each ignition part ,you will find it. most people start guessing and throwing lots of money at it ,bad idea /approach.

If you have a computer on your motor, borrow a laptop,buy the software and cable, diagnose the error, log all maintance.

Recheck the powercoil(org-org/blk) as voltage is 12V or more and meter setting was incorrect. Check that you have 12V on the yell/red into pack when cranking.

I have rechecked the org-org/black. I switched to "up to 20 volt". No readings when cranking.

No readings when cranking on the yellow/red into the pack.

The motor is on a stand without wire harness, and the VRO unit/fuel pump is disassembled. (Using WD40 in the cylinder for the cranking). I guess I still should have readings?

 

[Chris1956]

Mix up some 50::1 fuel using a real TCW-III rated oil. If she starts, you do not want WD-40 lubricating your motor..very bad.

The origin of the voltage for the yellow/red wire is the ign key start terminal. If you jumper power to the primary side of the starter solenoid (small wires) to crank the motor, you should see a path from the starter solenoid primary to the powerpack. Therefore you should see +12VDC on that yellow/red wire.

Black/orange and Black/yellow wires should be open, as they are the spark killers. when grounded.

 

[tommarvin]

Ditto,mix some 50:1, put the muffs on turn on the water, test with the motor running.

I'm a construction handyman, I have a voltage tester for AC, its like a large ink pen you touch the wire it beeps if power in the wire. I don't know if it will work or if they make one for DC, it sure is fast and easy.

It sounds like something is grounded out, try this get you glasses, flashlight, take a chill pill, start at back of motor,slowly work your way around the motor giving all electrical wires and connectors a tug and a twist, are the springs in place, do you see anything out of the ordinary, are all the wires tight, start at solenoid, starter, stator,trigger,coils cd module, last guy had a bad connection at the rectifier.

My approach is everything is ok inside the motor, find what's wrong outside the motor. Please tell us when you find it.

You should have 4-12vac on these wires when cranking. If you have nothing ohm the power coil and you have to have at least 10vdc on yell/red when cranking as this supplies power to pack till RPM is fast enough that voltage generated from org-org/blk coil/wire take over..

Thanks, I have done the testing with an ordinary multimeter, not with a DVA. I guess I will only need a DVA fot tetsting the powerpack/powercoil?

Ohm is 0,3. Maybe I should try to change the stator? Since it is grounded to the cylinderblock, I guess there will not be any grounding problems?

Why not try disconnecting the main wiring harness as it enters the engine. Then try jumping the starter to see if she fires. My 2000 Johnson 150 had a similar issue and when I separated the wiring harness and jumpered the starter, it fired right up. Needless to say I had great difficulty shutting it down!! I had to pull spark plug wires from the plugs until it stalled. After installing a new wiring harness from the key to the engine I have experienced no more starting issues.

Thanks, but I have already disconnected the wiring harness

Thanks. I have disconnected the plug wires to avoid that it should fire up while testing.

During the testing, I have jumpwired via the big, upper red terminal on the starter. No reading on the yeallow/red wire. But when trying to jumpstart from the solenoid, I get a 12V reading on the yellow/red wire, although it will not crank from there.

You may be doing the testing incorrectly. The output test for the 2 orange wires, is done by connected the meter between the 2 wires, not one lead to ground. The 2 orange wires supply voltage for powerpack logic. Check the output on the 2 brown wires coming from stator.

Hi, as I wrote earlier in this this thread, I have done the testing you mention. No volt readings with an ordinary multimeter.Do I need a DVA?

I do not what you mean with the two brown wires from the stator. Please see attched wiring diagram.

Your post ,test number 3 said no voltage between the 2 orange wires.==== Bad stator or bad testing​.

Using multimeter, set scale on 400 volts AC, redo test. multiply the results by 1.414 will give you the number you are looking for. Engine must be turning cranking rpms.

 

[clanton]

The 2 brown wires from the stator to powerpack provide voltage to the pack, to ignition coil, to fire the plugs.
Check the primary side of the ignition coil for voltage at cranking rpms, no voltage move to the 2 brown wires from stator, no voltage. replace stator

 

[Andrik]

UPDATE;

I made my own DVA to connect to the multimeter (found a description here in the forum), and I then found the voltage from the stator to be 23 Volts (brown and brown/yellow leads). As I have read in the Service Manual, it should be over 150.

The resistance is below the 550 ohms that the Service manual says it has to be (+/-55), I measured it to be 489 (brown and brown/yellow leads).

I guess I then can conclude with that I have to change the stator?

 

[clanton]

When using the DVA adapter meter should set on the DC scale, if you used the AC scale, retest with DC scale.

Thanks for good advise. I am an amateur on this. Then I got a 43 V reading.
