1991 Suzuki Super Six

[dsinger]

I have lost spark to one side like it is in safe mode. I have disconnected everything I can think of. Oil flow, shift interrupter, oil level, and water flow and still no spark. Pulled the flywheel and everything as far as sight goes looked good. No melted parts or lose wires. Can anyone tell me how to bench test the trigger with a direct voltage adapter. Or have any ideas as to what else it could be causing the loss of spark to on side. I think the CDI's for the most part fail complete and not just all three at once. Could be wrong. Any ideas would help.

I have just about any other part you could imagine outside Honda and Suzuki if anyone has a trigger timer base they wanna trade or sale.

I'm not at all sure whether you hav a low oil warning module on that year, but I removed connectors to CDI unit from the low oil warning module on my '87 DT 150 SS and that corrected my problem. If yours has it and you didn't disconnect it yet, that might solve your problem other wise the electrical check you are doing might turn up something. Suzuki did a lot of changes on the V6's from 86 up into the 90's so there may not be anything like that on your year model.

Ya I finally got the flywheel off. I think it is going to be the #1 coil charger. I cannot get both of them to give me a consistent reading. Think I will swap them and see if the spark goes to the other side.

Re: 1991 Suzuki Super Six

Most likely culprit on a 1991 is the CDI (backside of plate between the V ). They have 2 internal circuits..one feeds 1, 3 & 5 and the other 2, 4 & 6. In shut-down mode the ICU shuts off 1,3 & 5 but the ICU very rarely fails as compared to the CDI. You didn't say which side lost fire but if it is Port then CDI is practically a given, if Stbd. Then CDI but possibly ICU.

Re: 1991 Suzuki Super Six

I cannot remember seeing the CDI but I will go look and see if I can find it. What do you mean by between the V. I just figured it only had that on larger ICD that replaced the CDI. Thank you for your response and you seem to know a heck of alot more than I.
It is on the starboard side.

Re: 1991 Suzuki Super Six

You think I can just swap the two charging coil without causing any damage.

Re: 1991 Suzuki Super Six

Can anyone tell me if this motor has both an ICD and CDI. If so I cannot find it anywhere.

Re: 1991 Suzuki Super Six

From your questions it seems the first thing you need to do is BUY a shop manual and educate yourself before you spend alot of money you don't need to. OR.. take it to a pro. DIYCMM...do it yourself costs more money..true about 80% of the time.

Re: 1991 Suzuki Super Six

Not trying to beat a dead engine, buttttttt........did you try to see if the a low oil warning module is on this motor? My motor had strbd cyl dead when I got it. Disconnect the 2 connectors from the module that go to the CDI. (My motor runs fine now once that was done) Plugs will be inside the Coils area near the bottom of the box. This would be a simple fix before I'd go to the trouble of the charging coil, or trigger coil, whatever. And to my understanding about these motors, they don't very often have a CDI unit actually go bad. But what happens normally is that the sensors supplying info to the CDI? tells it to do Safety mode in certain situations. I would definitely get a manual to help with electronic test procedures, b4 I'd be tearing into it very much, unless you are familiar with 2 cycle systems.

Re: 1991 Suzuki Super Six

Thanks. From what I can gather the modal S series is internal within the ICU and it has no CDI. I had to send my meter off to fluke it was acting whacky and should have it back in a few weeks. I have a manual and understand the workings of most outboards but just not messed with Suzuki's much.
