1995 Johnson 50 hp no spark

[GP3998]

Model J50TLEOD. Battery was starting to get a little low, put on charger for the day, should be able to check again about 5 this eve. Thank you

 

[GP3998]

Sensor coil output is .946, ohms readings are the same

Try with the yellow rectifier or rectifier/regulator wires disconnected. If spark, replace the rectifier/regulator.

 

[GP3998]

No spark with rectifier disconnected. I am doing all my test with a remote starter button connected to starter relay is this a mistake?

 

[jakedaawg]

Fine as long as key is in the on position

 

[jakedaawg]

That's not the proper time base voltage.

I dont use a dva, I use a peak reading voltmeter but I think they are the same.

 

[GP3998]

Performed test again and come up with power pack faulty.
white/blue connect 86v, white/green connected 72v
disconnected readings are .6 and 1.18. Ohms readings for power pack; orange/blue to blue 70 ohms, orange/green to green 70 ohms, brown & brown/yellow are 10m ohms

 

[jakedaawg]

Those numbers are better. Bad pack probable.

 

[GP3998]

Will have part today, will install this evening and let you know. Thanks again

 

[GP3998]

No dang spark still. I give.

 

[racerone]

Perhaps look at post # 2 again.----Nothing else has worked / given you a happy ending.

 

[jakedaawg]

Have done that several times, everything passes. I got to be missing something.

Did you test for spark with the blk/yel disconnected at power pack?

test for spark that way .

 

[GP3998]

Yes, kill circuit working properly

 

[GP3998]

I will start again at post #2 thank you all for your help

 

[GP3998]

Got looking at motor again and stator output yest fails with only 200 volts. Looked at when I ordered part and ot was a 4amp instead of a 12amp. Are 4amp ignitions lower voltage? Did I find the problem? Thank you

 

[racerone]

The 4 / 12 amp refers to the BATTERY charging part of the stator and NOT ignition..----Perhaps 4 amperes at idle and 12 amperes to charge the battery at full throttle.------Keep trouble shooting on this motor !!

 

[GP3998]

The 200 volts should still be enough?

 

[oldboat1]

should be a 20amp fuse in the system. worth checking. "died like you shut the key off" sounds like a blown fuse.

 

[racerone]

Doubt a blown fuse is the problem.-----That motor can be started with a dead battery when pulled over with a rope.------Fuse is for the cranking / starting bits of the motor.
