Evinrude 1976 135 spark problems 683D

[Pacifictimes]

With the plugs in I get NO spark. I take the plugs out (leave one in with a sparker) and I get spark. I've taken my battery down to have it tested and showed good and charged. I don't have a tool to tell if its turning faster that 250 rpm though. I was thinking I would need to adjust the points to .020 but now that I've taken the flywheel off I don't see points.

All I can tell you about that problem is they had some bad timer bases on that motor that didn't have enough windings in them. Normally you just replaced the timer base and the problem went away. But it's funny the problem showed after all these years. OMC did make a tool to adjust the trigger gap to flywheel center magnet but don't have that info. Maybe somebody else will chime in with it. Re-check all your battery cable connections both on the motor and the battery.

Oh, one other funny thing, they came right out of the box from the factory like that. Was there to experience it.

A starter dragging will cause the same issue as will high resistance in battery cables. CDI makes a air gap checker for trigger.....

Save time, save money. If you don't have a DVA tester, get one. Then test the system to find the offending part. Option 2: Just keep replacing parts till it works. (Not recommended)

So where do I get a DVA (what does this stand for?) I am good with to tool to help. Today I inspected the wires for nicks, they look fine. So I put the flywheel back on just snugged its holding nut (no fuel to the motor) I put my battery charger on the battery and put it on starter mode (75 amp boost) I put all 4 spark plugs back in, installed the wires and kept the sparker on one. Checked it for spark. On all 4 cylinders I did get spark but only for a couple seconds, then none. I could give it a couple minute break and do it all over again with the same results. I can't say I truly know what a weak/strong spark is on the sparker just that there is visable spark but only for a couple seconds then nothing.

Per Fastbullet's comment: If the starter does not spin the crank at least 250 rpm's, the ignition system won't fire. Plugs out will allow the starter to spin faster. That could be from a weak starter, bad solenoid, dirty/corroded main battery cable ends, etc.

Page 3 of the link I posted explains it better than I can. CDI makes them, but isn't the only one. I haven't checked, but possibly here at iboats may have them????

Re: Evinrude 1976 135 spark problems 683D

I took the battery down and had a load test put on it today, tested good. I went over the positive and negative connections between the motor/starter and battery. I did cut one off and soldered a good one on , it really didn't look that bad but not worth any risk. So now I am looking at a starter dragging I can see it is loading the battery up so bad that it can only turn fast enough for spart for a couple or 3 seconds then just not enough cranking power. I've looked on IBoats but they do not show a starter for this engine. Suggestions? Is it worth rebuilding? I feel I should just buy new but not sure where yet.

Re: Evinrude 1976 135 spark problems 683D

I also had the same problem on another one and it turned out the battery cables were to small to carry the load.

Re: Evinrude 1976 135 spark problems 683D

Wow now thats a thought! I have always thought these cables look debateablely small. U have a feel for a conductor size (#) I should have. The negative is a decient size but the red is smaller. Also is there a way to load test a starter? I hate being a parts changer, but now have spark when the battery can boost the starter to turn the engin fast enough. Battery is good, connections all look good. Clearly the starter works but I have no way except to replace it, I do see they sell parts but if I don't know whats worn I'd rather replace the whole starter than to just replace parts till I get it.

Re: Evinrude 1976 135 spark problems 683D

Usually a starter will spin normally if you have a set of heavy duty automotive jumper cables and connect the starter direct to a known good battery. If it cranks the engine normally, it's probably ok. If the starter cranks it slowly, you could pull it apart and check the wear on the brushes. (and the com end of the armature.) Replacement brushes are still avail and the starters are easy to overhaul. If you get in there, you will need to clean out the large amount of carbon black prior to reassembly. Some Merc 24C grease (white lithium) works well as an armature bearing lube.

To rebuild a starter motor correctly you should have a growler to check the armature windings. Most rebuilds shops do.

Re: Evinrude 1976 135 spark problems 683D

i had similar problems with my 1995 evinrude 130. I had no spark and on very few occasions only one or two had spark. I replaced the power pack and that fixed it. Upon replacing, I noticed that my plugs and ignition coil had a lot of corrosion maybe they just need to be cleaned for proper contact. But replacing power pack did fix it for me.

Re: Evinrude 1976 135 spark problems 683D

Yea! Got it thank you Guys! :O) It was the starter turning to slow (dragging) new starter from MarineEngine (whom were amazingly FAST) and the engine has never turned over this fast. Probably been poor since I've owned this boat.
Another question First My plugs are NGK-BUHX are these good plugs for this engine? Nothing to gap on these. 2nd as I was running the engine on muffs at home last night it had one cylinder that seemed to be hitting occasionally, so raised the rpm hoping to warm it up and maybe getting it to fire. After maybe 7 or so minutes (??) I noticed an instant load pickup so I quickly idled it down, it quickly died. I waited about 30 seconds and just gave the starter a hit and it sounded more like a grinding of the starter. So I just stopped, turned the water off and went back and turned the flywheel (afraid I might had burned it up, and locked it up), the flywheel turned what seemed normal, but I could hear what I thought my be the water pump impeller rubbing. On muffs should you not idled it up, can you not get enough water to the pump like this? Think I destroyed my pump?

Re: Evinrude 1976 135 spark problems 683D

I went back out this morning and cleaned the spark plugs with acetone they cleaned up nicely (new plugs just a little black oil from the run yesterday). I turned the flywheel all I felt was motor compression did not hear anything from the pump on the lower end. So I decided to give it another shot at starting. Soon as I hit the start the new starter locked onto the flywheel and just sounded like it internally just ground (only a second and I stopped) I thought I seen some dust coming from the inside of the starter (probably fine metal flakes), it looks like it is trying to push higher than the flywheel will allow it to (or than it needs to). But it does not turn the flywheel at all.

Re: Evinrude 1976 135 spark problems 683D

Hard to believe but you could have a bad new starter. Was it new or rebuilt ??

Re: Evinrude 1976 135 spark problems 683D

New as far as I know $200 got it to my front door. MarineEngine has replied already stating Monday they would give me instructions. I am guessing to send it back. Yeah not much you can do wrong, 3 bolts it in one place only add the positive lead and you are done. I am a bit bothered though it appeared to be pushing the sprocket higher than necessary to the point the face plate on the starter gear is rubbing so hard it is scratching the face. Something I would think should never even touch. Makes me wonder if it was jamming its self and caused it to strip its own gears out. Will the next one have the same problem? It says it is an OEM product replacement.
Boobie any thoughts on the other questions I had regarding water pump and high rpm and types of spark plugs?

Are you sure about the model year?

Re: Evinrude 1976 135 spark problems 683D

Got a new starter (again), and this one works great. but now I notice I have spark on one of the cylinder sets (1 & 3 have spark) 2 & 4 have NO spark.
CDI says to swap the timer base wire sets (1&3 with 2 & 4) - hmm not sure how to go about this any suggestions?
