I have a 1977 Johnson 70hp motor.I'm getting no spark to all three cylinders.How can I check the power pack?

I'm sorry most of my experience is on larger equiptment, however, I've had plenty of time on outboards. It would be best to attempt to find a manual (public library) and look into trouble shooting. The book will give the specific ohm for each power pack and run you through a sequence to check them. Good luck
