Back agina with the 1984 125

Okay i have been able to rule out the CDM box. #3 &#4 still not getting spark (unless i switch the CDM boxes around). So what is the next step and what is te best way to get the flywheel off?

Okay i have been able to rule out the CDM box. #3 &#4 still not getting spark (unless i switch the CDM boxes around).

Do you mean to say if you switched #3 and #4 CDM with #1 and #2 CDM you get sparks on #3 and #4 cylinders? If the answer is yes, that means the CDM feeding #3 and #4 is bad and needs to be replaced. Or am I reading you incorrectly?

 

[Fatbs]

I believe you are reading it correctly. Since i was getting fire on 1&2 i unplugged that CDM (A) and plugged CDM box B into that plug and got fire to 3&4. I did not switch plug wires or any wires that connect to the coil. I only switched the the plugs that have 4 wires to it. i think a red, white with green, orange, and green wire. i was thinking the same as you however, if i switch ed plugs and got fire on 3&4 then how can the CDM be bad? I am thinking now it is going to have to be something else. Something that is not getting power to that plug in...It may help if i learn the names of this stuff instead of that and this plug in....

From the color codes that you're referring to, it sounds like those are the trigger wires. I would have expected the stator wires which are the two sets of Blue and Yellow wires.
Anyways, it's easy to check the trigger. With the plugs disconnected you should read 48-52 OHMs between the trigger wires. There are two pairs of White/Green and Red wires and two pairs of Orange and Green wires. You may have a bad trigger, or a broken wire(s).

I am not much of a OHMs person YET...lol...So is with the key on? How do i get the reading? I have a meter but very like idea on how to work it.

No Title

No, the ignition switch has to be off. Here's a wiring diagram. From the color description it seems you are referring to the trigger wires as mentioned by PNW. If what you switched are the trigger wires (wh/grn & red and the other set of grn & orange) and you got fire on #3 & #4 then that is an indication the CDM's on both sets of plugs or cylinders including their associated coils and spark plugs are OK. Now the problem is with the trigger or the trigger wires.

Before going deep into the trigger, you need to visually and manually and physically check the suspected wires first. Sometimes, the problem is with the connector plugs being corroded or dirty and losing contact. Disconnect the wire connector plug (feeding #3 and #4 CDM or CDM-B) clean and then measure resistance between each set of wires. For example, place your multimeter in resistance reading (indicated by the Greek letter Omega) touch one probe to the red wire and the other probe to each corresponding set of wires, i.e. white/green. And then do the same with the other set of wires, green and orange. Readings should be 48-52 as mentioned by PNW.

Okay we have a winner.....lol... sorry guys like i said this time and the next i work on a force outboard (well really any outboard) will be the only two times i have done it.n After a lot of switching wires around i can how say it is the blue and yellow wires. The stator wires. So must i replace the stator?

 

[Jiggz]

It is quite unusual that it will be the stator considering the other CDM-A is working properly as indicated by sparks on #1 and #2. Maybe the stator wires feeding CDM-B are broken or loose. But not necessarily the stator. You might want to double check before shelling out your $$$!

 

[Fatbs]

I have found a little brunt out spot on the stator right where one of the blue wires connect to the stator

 

[Jiggz]

If the burnt spot is on the laminated coils of the stator, the only remedy is to replace the stator. However, if it is on the wire itself, it maybe fixable depending how much time you want to spend or money to replace it.

 

[Fatbs]

I am pretty sure it is on the laminated coils of the stator (just my luck). I want to thank everyone for their help and i will continue to keep you updated because i am sure i will be having more issues.

It will be for the benefits of all forum members that you post the final conclusion or fix to your problem as soon as it becomes available.
