1970 envinrude no spark

[nektwister]

Hi all my lil brother just bought his first shipwreck i mean boat it has a envinrude triumph 1970 60 horsepower the guy that sold the boat said it ran "of course" but we changed the fuel and plugs and cranked away. No spark at all there appears to be a new coil and I think timer base under the flywheel matter of fact everything under the flywheel looks new plug wires all that. Too bad no kill switch I could fix that compression is good on all 3 cylinders going to get clymers manual now any help would be appreciated. Thanks in advanced cause I've always gotten help from this site.

How's the battery h2o? One thing you gotta' have for this ignition system is a GOOD battery. You got to have 12V's to the amplifier. 10 or less and you will blow the amp. Pricey black box at around $320. Check the voltage on the purple wire to the amplifier.

i Had a 1972 50 hp same problem so i replace the timerbase the stator unit but you said yours looks good. I found out also what was causing no spark was my power pack. It was bad. Maye that is what it is on yours. I hope you get it running they sure are nice motors. good luck

Re: 1970 envinrude no spark

Hey thanks for the input I will definitely check both of those out the battery was brand new 750 crankin amps that baby spun like a top what about the points someone told my brother it could be the points new to me I will do some more investigating tomorrow and keep everyone posted can't give up it was only 200.00 for the boat and all so a couple hundred won't hurt him. Thanks P.S there is 3 wires tied into each other and covered in a hard plastic wax like ball any ideas what this could be ?

There are points under the flywheel h2o. Gotta find something for you...just remembered. I'll edit the post when I find it.<br /><br />EDIT: Found it. Joe Reeves who is probably one of the most knowledgable folks here on the forums has a test you can run on the amplifier to see if that much of the system is good and your getting voltage from the amp. Here it is. Read it carefully and give it a try. May save you a bunch of headaches.<br /><br />(Battery Capacitance Dischage Powerpack Test)<br />Various OMC Engines - 1968 to 1972)<br />(J. Reeves)<br /><br />Purchase a small 12v bulb at your local automotive parts store (the 12v bulb is to look like a flashlight bulb, not a headlight bulb). Solder two wires to that bulb, one to the side of the bulb (ground), and the other to the positive point. You might use a bulb of a somewhat lower voltage to obtain a brighter glow... just a suggestion.<br /><br />Remove the spark plugs. With the key in the on position, make sure that you have 12v going to the pack at the terminal block (purple wire). Now, connect the ground wire from the bulb to any powerhead ground. Connect the wire from the positive point of that bulb to the powerpack wire that is connected to the coil wire on the terminal board (blue wire). <br /><br />Crank the engine and observe that bulb closely (CLOSELY!). If that bulb glows even the slightest bit, the powerpack is okay. It may be a very dim glow... just so it glows! If it doesn't glow, the pack has failed. <br /><br />Keep in mind, that type powerpack (Battery Capacitance Discharge) demands a top notch battery of at least 70 amp hours. Any less will, in time, cause powerpack failure.

Re: 1970 envinrude no spark

Hey obj I tried the test and to begin with we had no 12v current with the ignition switched on and I hooked the bulb + to the purple wire from the power pack that was hooked with the blue wire from the coil , fully charged battery and cranked the motor without the plugs and no faint glow or light at all even tried a lesser volt bulb . I checked for power across the board and have power but nothing at the purple wire with the ig switch on. Any ideas ? gonna order points tomorrow Should the ig switch be sending a signal or something? If you think of anything else it's appreciated and I'll keep all posted of my findings.

Re: 1970 envinrude no spark

Keep us adviced, at least me, I am still having the same problem with my 65 Johnson. I got the manual and still going threw different test. I have no glow either and have a deep cycle battery that is fully charged.

Re: 1970 envinrude no spark

Check the 20amp fuse at the motor. If this is blown, you won't get voltage to the ignition switch. When the ign switch is on, the 12 volts is supplied to the amp.<br /><br />EDIT: Check for voltage at the ignition switch on the pruple wire. If the fuse was blown, the engine wouldn't crank. Just re-read your last post....

Re: 1970 envinrude no spark

Hey anybody know where i can find a tune up kit for this motor 1970 evinrude 60 horse model# 60073d. Yes I checked iboats parts store and it doesn't give me the year for the triumph. Or anybody know if it's interchangable with another part number for johnson.

Re: 1970 envinrude no spark

There really isn't a tune-up kit that I know of. The points PN383655, is no longer available from BRP. You could try TwinCity Outboard, seaway marine, ishopmarine....all have sites.<br /><br />Are your points bad? What do the contacts on the rotor look like? Have you checked for the 12Volts at the purble wire at the ignition switch?

Re: 1970 envinrude no spark

OBJ haven't checked for the 12 volts yet just was told that the points were no longer available and thuoght if i could find em i'd buy a set or two just in case i will check for the 12 volts today and post the results. Thanks <br />Is that the original part # because the guy i talked with said he could cross reference them with the original number.

Re: 1970 envinrude no spark

As OBJ states, you need 12 volts being applied to that Purple wire which leads to the amplifier before anything can be checked.<br /><br />The fact that you can crank the engine via the ignition switch proves that the power fuse is okay (voltsge being applied to the switch).<br /><br />Depending on what kind of ignition switch you're using, voltage to that amplifier purple wire would be supplied via either the "I" or "A" terminal on the back of the switch.<br /><br />Time to get the volt and ohm meter out to see why there's no power going to that amplifier purple wire.

Re: 1970 envinrude no spark

h2o, if your Amp is bad, you might check on Ebay, there is one on there for a 5.00 starting bid, the # is 389550, check your # on yours it might be worth bidding on. I got one for my 65hp for 80.00 buy now, I was told at the boat shop it would cost 335.00.
