1989 force 125 stator problem

Re: 1989 force 125 stator problem

CDI stands for capacitive discharge ignition. CDM may just be someones acronym for Capacitive Discharge Module.

The rectifier only changes ac voltage to dc voltage. It uses a separate coil in the stator and does not even have to be connected for the engine to operate. The main parts of the ignition system are stator, trigger, CDI module, coil, plug and ignition switch. Any and all can cause problems with running and starting. You need to trouble shoot and eliminate as many variables as possible.

One way to do this is to substitute known good units for unknown quality units. Say, if number one cylinder is firing fine, but three isn't, try swapping the coils first, if that doesn't work, try swapping the CDI module etc.

Merry Christmas,

John

Re: 1989 force 125 stator problem

ok heres the deal. ive replaced the stator, trigger, and plugs. i am still not getting fire on cylinders 1 and 3. pulled them off to check for spark. had it on 2 and 4, just not 1 and 3. i have ordered a new ignition, and hope that fixes the problem. any more ideas for me to try???? im getting a little discouraged here. the seloc book is a little confusing on the tests, and says if there is no fire on 2 cylinders to check the stator, but as i said before the stator and trigger are now both new. please give some advice any and all is appreciated. thanks guys!!!!

Re: 1989 force 125 stator problem

ok i swapped all 4 coils on the ignition module. 1 and 3 both got fire when swapped on the modules, and vice versa. so by my deductive reasoning, i have 2 bad ignition modules. from what the book says cyl 1 and 2 are run off of module 1, and cyl 3 and 4 are run off of module 2. so do i need 2 ignition modules???? as i said all coils get fire when swapped. please help!!

Re: 1989 force 125 stator problem

It appears that you have one circuit on each of the modules that is inoperative. Since they are expensive, I would double check and swap again just to be sure.

Remember that whenever troubleshooting or running, have a grounded plug or spark tester attached to each coil lead. Failure to do so results in premature CDI module failure due to the back feeding of the high energy pulse.

A fellow is currently parting out a 1984 85hp on ebay. The modules from that engine will fit your 125. The other option is to go to CDI.com and buy them from them.

Hope you fix the problem before spring.

Re: 1989 force 125 stator problem

well i found the module online for 195.00 the guy on ebay is selling his used one for 165.00. that really sucks i need 2 of them. so since i have a new stator, trigger and soon to be new modules, is there anything that may cause this to happen to me again, something that caused the whole problem???? maybe battery problems, or wrong voltage battery??? any reply is appreciated. thanks for your help john!!!!!!

Re: 1989 force 125 stator problem

Probably the biggest killers of modules is poorly maintained engines.

When engines are not kept maintained properly, they usually become hard to start resulting in excess use of the modules at low voltages. This plus excess troubleshooting by people who fail to ground the spark plug wires eventually leads to premature failure.

If you keep your carbs clean and adjusted, plugs clean, good diaphram, clean fuel, timing and sync correct, you should not have any problems.

Good luck,

John

Re: 1989 force 125 stator problem

Try these folks if you haven't already ordered the modules. You have to call them up. Wholesale cost on the blue ignition modules is $71.34. List is around $100 bucks. I called them up and insisted on the $71.34...they finally agreed since that's what they showed on their WEB site and it doesn't say anything about wholesale price. Plus these are brand new units.

NOTE: P/N for the blue units is 92-5104, black units 92-5040

I have 2 of those power packs. Check your PM's

I have a blue cdi module ill let go for 40

Re: 1989 force 125 stator problem

ok the guy i bought my boat from titled the motor wrong. its an 87 force a model 125 hp. i have changed the stator,trigger,and cdi modules and still no spark on 1 and 3 cylinders. i swap the coil plugs on the cdi and i get the spark to 1 and 3 then. what the heck else is there to change other than the coils????? i dont know what to do now except to change those now. please help!!!!!

Re: 1989 force 125 stator problem

This is what you had on January 25th.

ok i swapped all 4 coils on the ignition module. 1 and 3 both got fire when swapped on the modules, and vice versa. so by my deductive reasoning, i have 2 bad ignition modules. from what the book says cyl 1 and 2 are run off of module 1, and cyl 3 and 4 are run off of module 2. so do i need 2 ignition modules???? as i said all coils get fire when swapped. please help!!

Are you saying that you have the same problem even when you installed new parts?

Re: 1989 force 125 stator problem

yes same problem with all new parts. its all cdi parts: stator, trigger, cdi modules, but still the old coils, but 1 and 3 get fire when swapped on the modules. so what do i do now???

Re: 1989 force 125 stator problem

Look for a bad connector or a bad ground. Write down what wires you checked and what the resistance is so you don't repeat your self. Assuming that you parts are good, your problem is in the wiring.

ok ill start there thanks john i appreciate it

Re: 1989 force 125 stator problem

ok i ran all the wiring, and its all good. the new stator is reading 333 ohms, (new cdi stator) and the new cdi trigger is reading 90 ohms. the old one reads 49 ohms. not sure what the magnet is supposed to look like, but i checked it and it looks ok. not loose at all, still magnetic. i did find that my rectifier is bad, and will replace it. not sure what else to do now.

Re: 1989 force 125 stator problem

Did you check the wiring at the terminal strip or at the connectors for each component? The reason I ask is that you may have a high resistance in a connector or spade lug.
