No spark 75 1000 with Dyna S...

#1

Post by wingrider »

Hey all,

Seems this 75 that I have been working on decided today it didn’t want to start.

No spark at all. Ran fine yesterday. Today I changed out the water pump, so radiator and front cover came off, but nothing else was changed from yesterday.

What can I check to see that I not missing something silly. Main fuse looks good, turns over fast, and battery is at 13.2 volts. Kill switch is set to run.

Any ideas? Thanks for any help!

Might have knocked the power wire off of the coils. No fire at all and you did some work. Look over everything you were close too. ;)

I checked all that as well. Good reminder though. I am going to try and re seat the wires on the S unit. Don’t know if it will help, but here’s to trying! anim-cheers1

Well, not sure what pushing and shoving did it, but spark has returned. There was quite a bit of dust in the cover over the Dyna S...regardless now, she runs again!

I think I'd be taking a real close look at the primary ignition wiring and connections. If you don't really know what fixed it, that's a gremlin that will come back to visit - and most likely at the worst possible time...

That is on the books for the afternoon. No point setting it up to fail.

I had intermittents with loose male-to female bullet connections for bypassing the ballast resistor. Give the females a squeeze, they like that.
Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.
