Gs450 Ignition circuit trouble

[GsRocket]

All,
This has brought up a very interesting discussion and i will consider switching the wires after it is running fine again so i can see the difference in voltage. In the meantime its not a charging issue, i'm still working on getting spark. I guess i mistook the RR to affect spark when really its only charging. Am i correct to assume that the only reasons for it not to spark would be connections, my signal generator, CDI ignition box, and the coils? I'm not sure how to check the CDI or the signal generator. Because of the timing i noticed the broken ground it probably fried something, just not sure what.
Thanks for all the input so far.

Your electrical system needs to deliver a decent voltage ( maybe > 11 volts) to ignitor in order to get things to fire happily. Having 13 volts at battery doesn't mean the ignitor sees this, as connection losses take their toll. Engaging the starter makes things worst. The power goes from battery to fusebox on to igntion switch and on to kill switch and then heads to coils and ignitor. Double check these places and measure voltage at ignitor . Basscliff's site has some good ideas on testing ignition components.

Yep, +1, this is why I was saying to eliminate any voltage loss first.

There will be a point at which too much voltage drop causes things to stop working. I'm not sure what this point is, but if you end up with 9v at the ignitor for example, this may be too low for it to drive the coils. Same with the coils, there is a point where the spark will become too weak to fire anything...

Also, if you do various tests while there's not enough voltage, it may even make you think components are faulty when they're not.

The ground wire directly on the R/R may not impact too much aside from the R/R but I'd still take care of it first with the rest of the connections.

As for testing the ignitor (it's not a CDI ) and signal generator, the Clymer manual has tests for these which can be downloaded from BassCliff's site.
