I have no power at the ignition coils and have no idea why? everthings plugged in.. got any ideas why this COULD be happening?
thank you and this question is for a 1989 Honda CBR 600 F1 Hurricane



Thank You

OK, look at your wiring diagram. At the top is the Fuse Block where the fuses are located. The right fuse (in the diagram) is a 10A fuse that shows a Black wire coming out of it.
That line goes straight down to the Starter Switch. Just before it gets there, it branches off and goes over to the Engine Stop Switch. If power makes it through the Engine Stop Switch, then it goes over to the 2 Ignition Coils and also to the Spark Unit.

Just like you did before, connect the black lead from your testor to the negative terminal of your battery. Then you'll move your probe from place to place following the flow of electricity from the 10A fuse to the Starter Button, on to the Engine Stop Switch, then onto the Coils until you loose it.

Following line 18 you'll see that it connects directly to the coils and the Spark Unit. The line that makes the coils spark is the Y/L and L/Y wires. The Spark Unit gets signaling from the Pulse Generator. But even if the Spark Unit is not doing what it's supposed to, you would still have battery voltage on the Black wires which we need to see if you have.

 

I have between 10.4 and 10.9 volts on both coils and absolutely no spark... before they stopped sparking completely I could hook up jumper cables from my truck and it would start right up but only run for a minute or two then die and not start back up for a good while... I'm no good with eletrical crap , someone please help !! I have a 1988 CBR1000F Hurricane by the way...

 

I would hazard a guess that the battery is faulty / not being charged if as you said it initially worked when jumped from your truck then died!
What voltage do you have across the battery? A load tester would be good in this instance.

 

You have three choices it seems

1. Invent a time machine and go back to the 1700's (probably will require electricity)
2. Pay someone who doesn't think electrical stuff is "crap" to do it for you
3. Stop being a baby and start learning how electrical "crap" works - you have a bike that has the least amount of electrical crap you could get, other than something out of the 50's. If you can understand plumbing, you can understand the electrical system of an 80's honda.

 

Completely dead battery!!! Should be 13.5-13.8v fresh off chargers. There's not enough power to run ignitor.

EVERYTHING may be perfectly fine on bike. Dead battery's just keeping it from starting.

Easy test/fix is to jump-start bike from known-good auto battery. Leave car OFF, we are just borrowing its battery. Should learn to use jumper-cables anyway in case you get stranded out in middle of nowhere with dead-battery. And learn to bump-start bike so you can start it with no jump-start help around.
