m4f1050 Posted December 4, 2010 Report Posted December 4, 2010 Is the manual wrong or do I have 2 bad coils? Neither of them will read the 4.7k ~ 7.1k ohm that the manual says. Quote
AKheathen Posted December 5, 2010 Report Posted December 5, 2010 test them from cap to cap. remember, most caps are 5k, so it can read as high as ~16,000. if you get nothing this way, take one cap off at a time, and test. still nothing- take the wires out and test right in the coil.... Quote

From cap to cap? So I don't use primary ground to test secondary like what the manual says? I'll give this a try and post findings.. Quote
m4f1050 Posted December 5, 2010 Author Report Posted December 5, 2010 (edited) Well, well... Manual was wrong... I found this post and read it.... http://bansheehq.com/forums/index.php?showtopic=133650 Thing is,... I have 2 coils and both read - - (open circuit..!) Could both be bad? I have the Ohmmeter set to 20k so I should be able to read something... Also, can I use an osciloscope to measure a "pulse" on the Orange cable to test the CDI? If I can, what is the voltage of this pulse? Thanks! EDIT: Ok, here are my findings.... Removed all 4 boots and both coils read 5.7k ~ 5.8k (so that's good) But why are the boots not reading at all? All 4 read open circuit no matter where I set the ohmmeter? 20K, 200K, 2000K, they all (4) read OPEN circuit... Could all 4 be bad or I can't check this resistance?

AKheathen Posted December 6, 2010 Report Posted December 6, 2010 the caps are just brittle cores that can, and do crack/deteriorate, just like resistor plug wires on your car/truck, which is why you replace them regularly. now, they usually still spark for quite some time after they crack, but resistance goes up, and vibration makes it inconsistant. if they are all old, i'd immagine they need replaced. as far as usin an osciloscope, you can use one on the stator to see a bad flywheel magnet, but the cdi is a capacitance discharge ignition, so it's going to build and store energy and discharge one pulse at a time, and i have no idea what it should measure, or where to find out, aside from measuring a known good system Quote

That shouldn't cause no spark situation I am having. Everything leads to bad Stator.. Specially being a Ricky Stator that everybody complaints about them. Quote

Specially being a Ricky Stator that everybody complaints about them. no spark at all? and you ohmed it all out? also, check the flywheel magenets....they should be 12 evenly spaced, if you slide a screw-driver on the inside Quote

I am going to check my grounds again, just in case. But 11ohms is a bit too low isn't it? I couldn't losen the nut so I couldn't take the flywheel out. I have to take the banshee to my old house (my parents live there now) I have the compressor and impact wrench over there... Quote
