1990 60hp evenrude no spark

[mitch que]

i have a 1990 60hp outboard im not getting any spark to the pugs one of the coils was cracked but im not getting spark from the other2 coils
i had the motor cover off for an evening while it was rainning but i had a trap over it to keep the rain out .. i have had it back fire a couple of times so every once in a while it will get a spark but nothing constant while turnning the motor over . so whats next ?i dont want to take it to a shop i know theres a power pack and some other stuff that maybe causeing the no spark and i already replaced the small inline 20amp fuse <the old one was ok .

any seggestions will help ty

Re: 1990 60hp evenrude no spark

Start with the obvious, check connections to the powerpack and for corrosion, grounds as well. Intermittant spark can be caused by a bad wire for starters, move some of the power pack wires around while someone cranks it. You could try disconnecting the big plug going from the remote controls to the motor and try jumping the solenoid to get it to turn over, that may isolate ignition switch / lanyard issues. Next steps after that will require a multimeter with a DVA adapter and a manual/directions for each test.

Re: 1990 60hp evenrude no spark

thanks bki have cheacked all the connections and it does turn over with no poblems everything as far as corrosion and being loose i found nothing in that way
mare you talking about the big red plug ? if i unplug that and tune it over i should have spark?
and then if i unplug it and i still dont whats next?
i see there are a few componants that make it fire but i dont want to change things out that are not bad for the cost of some of theses things can add up real fast thanks mitch

Re: 1990 60hp evenrude no spark

You might get spark if it is a problem going up to the remote control. And no you don't want to change out parts that you don't need to, that's why I recommended you pickup a manual as a starting point to help diagnose the problem, this is merely armchair mechanics 101, it's guess work without the motor in front of me.

Re: 1990 60hp evenrude no spark

thanks bk i am looking to get a repair manual now i read another post where the advice was to unplug the big red wire conetor then turn it over and see if i get spark i take it this will eliminate the throtle control and ingnition switch which dosent make sence to me does it to you ? by the way i have cheacked my coils for continuity even the one that is cracked and they test good as far as passing current

Re: 1990 60hp evenrude no spark

ok i disconected the big red plug got a remote starter swith and disconected the spark plug wires turned it ove r and wow i did get spark ill the way down to my toes <i got shocked>.lol i reconnected the spark plug wires and still with the big red plug disconnectred i started the motor up cool
so the problems in the key switch box area?
what am i looking for there ?
turnnning the key switch the engine does turn over real good i looked at the leash and cant tell if anything is wrong there but should i take the box apart to see whats going on on the inside?

Re: 1990 60hp evenrude no spark

Has that remote control box got a kill or lanyard switch?

Re: 1990 60hp evenrude no spark

yes bk the king it does i looked at it from the out side and it does not seam to move when the lanyard is pulled onyou have no idea how much your helping me ...

Bad switch will cause no spark, pull it apart and test the switch.

Re: 1990 60hp evenrude no spark

ok i will try that thanks bk you are the king ..

No problem, glad you are getting closer to getting her back on the water.

And the king thing isn't self bragging, it's my last name LOL.

Re: 1990 60hp evenrude no spark

ok i took the control /throtle box apart and cheacked the kill switch for contiuity and i tested good
i also looked at the 6 wire temanal with a light tester in the off pos.
i had one termanal getting juice with it in the on pos. i had the first one and one more showing i was getting current to there should any of the other termanals be getting current?
i also cheached what i think is called the netral safty switch with the volt meter and its working also so maybe the ingnition switch is bad?

Re: 1990 60hp evenrude no spark

Certainly a possibility that the ignition switch is bad, as a test you could always take the stop switch out of the equation, it is connected to the "M" terminal on the switch, should be a black and yellow wire. This is going by a clymer POS manual of course.

 

[bktheking]

Re: 1990 60hp evenrude no spark

BTW the kill switch should not have continuity unless it's closed, open should not have any continuity. If it has continuity regardless of it's position that would be the issue. As I said, remove it from the equation and retest.

Re: 1990 60hp evenrude no spark

ok im confused with the swtich <kill> open or closed i should not get any continuity ?
when it is in like it was actavated i think i should show a circut no?
and out it should not show anythinh on my meter?
and i also calles iboats and there not sure what ignition switch i have most of theres are a 5 wire termanal mines a 6 wire and they dont go by a year just a part number any help there ?
they also dont show a new kill switch as far as i can see
thanks

Re: 1990 60hp evenrude no spark

if it back fires or you get a little bit of spark some times and not other times it sounds to me it might be wet or damp under the fly wheel even a tarp wont stop water from getting under the fly wheel especially if the cover is off. it wont take much,even a little condensation can fool you try the easiest root first take a hair blower and try to blow as much air as you can under the fly wheel for a minute or two then try for spark if that dont work i suggest you take the fly wheel off and clean your points not by taking them off just take a small piece of cardboard from a match pack or cigarette pack open one set off points put the piece between the points then close the points then gently pull the cardboard out you will be surprised the brownish or black color that will be on the cardboard repeat a couple times on each set of points it does not take much for the points to mess up also make sure the kill switch and every thing else is all hooked back up before you check for spark hope that helps

Re: 1990 60hp evenrude no spark

aw no 45 it didnt cause i have already had it running when i unpluged the red plug with bks help we have narrowed it down to the remote box so far but thanks for you efffort

If it's a lanyard type switch with the clip , you should only get continuity with the clip off, not on. The clip off would ground out the powerpack I believe according to the wiring diagram.

Re: 1990 60hp evenrude no spark

bk the clip rocks on a piviot and its all plactic... the switch has 2 wires comming out of it .inside the control box , 1 going to ground and another going to the ignition switch the one thats going to the ing switch is joined with another one at the same termanal .. i dis conectted the ground one and guess what?
not only do i have spark but i have lots of it and i fired off the motor way cool' thanks a bunch you were a great help regaurds capt mitch ....

Re: 1990 60hp evenrude no spark

No problem, don't forget to replace that switch, it must be grounded inside, it's a safety issue. That's what I meant by removing the switch from the equation
