1991 Johnson VJ150SLEIE Spark

Re: 1991 Johnson VJ150SLEIE Spark

Just got off the phone with CDI and they confirmed that the stator was indeed wired incorrectly and the power pack waz dead on one bank. They repaired stator and replaced pack. I am so upset about this whole situation. Their error has cost me 3 weekends of boating, a good spare power pack, and $50 in shipping charges. I tried calling them all day yesterday and today to make sure that they would overnight it and was told today that it had already been shipped and there was nothing they could do and that they were sorry. This has gone beyond "Sorry". "Sorry" just isn't going to make this right. Anybody know who I can call or write to file a formal complaint. It is so difficult to get any response from this company.

Re: 1991 Johnson VJ150SLEIE Spark

Installed new CDI parts today (timer base, power pack, and stator) and idle is really high (2000 rpms) on hose. Idle timing is 6 btdc. Temp sensor is working properly and there isn't any stray voltage on yell/red wire. Disconnected black/wht wire from timer base and it made no difference. Everything points to faulty pack. This is a new pack that I just received today directly from CDI. Any ideas? I have lost all confidence in this company.

Re: 1991 Johnson VJ150SLEIE Spark

CDI is a joke. Wish I could return the $1000 woth of CDI parts that I have on my engine. Warranty is useless if you can't use your boat. I don't want a warranty, I just want a part that actually works. I will never order from this company again or advise anyone else to do so.

Re: 1991 Johnson VJ150SLEIE Spark

Idle timing is 6 btdc.

Is this a typo? It should be around 4* ATDC. Not BTDC. Can you adjust it back down to 4*ATDC. It will slow down considerably.

Re: 1991 Johnson VJ150SLEIE Spark

Not a typo. Checked stator DVA at idle and got the following:
Brn - Brn/Yel -- 590 V
Brn/Blk - Brn/Wht -- 460 V
Org - Org/Blk -- 13 V
These voltages lead me to believe that my new CDI pack is not regulating the stator voltage like it should.
Tried to adjust down to 4" ATDC but new power pack dropped the port side bank before I could adjust the throttle cables.

I then installed my old power pack that had blown on the strb bank (Caused by incorrectly wired stator from CDI which they didn't replace). Stator DVA at idle was as follows:

Brn - Brn/Yel -- 1.8 V
Brn/Blk - Brn/Wht -- 290 V
Org - Org/Blk -- 22V

Re: 1991 Johnson VJ150SLEIE Spark

Are you taking these readings with stator and pack connected? I assume yes.
I don't think the pack "regulates" the input voltages.....any regulation will be on the output at the coil primary wires.
Should be down around 190-200 vDVA. Maybe higher...I haven't looked up your specs....just looking at these voltages in a general manner...

I don't see how a pack can regulate down the input....but still....that is really high. You sure on your metering equipment?
I guess so, since you are getting normal readings on the bad pack....except for the 1.8v of course.

Regarding the 1.8v with the old bad pack...yes if the input to the pack is shorted, or has a very low input resistance, then it can haul that stator voltage down like that.


I hate it that you are having such a problem with CDI. It definitely sounds like the new pack is bad. But....didn't you say they sent you back a tested pair..stator and pack?......geeezzzzz.

For what it is worth....I heard a while back that CDI was making the OEM OMC parts for BOMB now....anyone know if that is true?

Re: 1991 Johnson VJ150SLEIE Spark

Just got off the phone with Clark at CDI and he too thinks that the pack is bad. This pack came directly from CDI as a replacement for the pack that got blown because of the new CDI stator being wired wrong. He said the he would try to expedite this and check it himself when it comes in. Also said that he was going to pull some of the inventory that he had and check them too. The voltage thing didnt make sense to me either but I read this on CDI trouble shooting page.

"1. Connect a DVA meter between the brown and brown yellow wires and do a running test. At no time should the voltage exceed 400v. If it does, the regulator circuit in the power pack is bad."

Re: 1991 Johnson VJ150SLEIE Spark

Well....I will have to defer to the quote from CDI....
I still don't quite understand the concept of "regulating" the input of a device. Regulating it in such a way that the voltage is lower on the input....
Normally the voltage will be applied to a regulator, and the output is what is controlled.

There are clamping circuits that will hold a voltage down to a certain level....ah well....no point in guessing....they know their stuff best.

Good luck with the resolution. It sure looks like CDI will be to only way to fix this problem at this point.

Re: 1991 Johnson VJ150SLEIE Spark

Finally gave up on CDI rushing me a replacement pack. Ordered new pack on Tuesday and installed it on Thursday. Runs great now. Shipped faulty CDI pack back to them on Monday and haven't heard anything from them. Guys that I have talked to seem like genuinely nice guys but may just be overwhelmed with work.

Re: 1991 Johnson VJ150SLEIE Spark

I had a similar issue on my '97 J200-TXEUA. Replaced power pack w/ new Sierra and while installing it I found the Brn/yel wire from the stator to the starboard packin the 2-pin plug rotted through and not making connection. I repaired the connection w/ new pin & put everything back together and the motor started and ran great on the hose for a few days. It continued to start each time trying for about a week then later I tried starting it again and no spark. Checked kill switch circuits everything is fine. I am now focusing on the timer base as it fails the "sensor coil ohmmeter test" of step-5 in my shop manual. Step-4 tests OK for the "charge coil test" and stator voltage =130V, no shorts to ground, and the 838-ohms for each coil so that test tells me the stator should be OK.

Did your timer base check OK or did you have to replace it too with the new stator? Does anyone know if I'm on the right track w/the timer base problem? Can a bad timer base or rectifier blow the power pack again?
