endofitall9 Posted March 28, 2007 Report Share Posted March 28, 2007 (edited) Well here it is guys....The banshee died! went riding a couple weekends ago and at the end of the day on the way back to the truck it was acting like i was foluling a plug or something.....they were brandnew! Anyway about a week ago i get some works shocks and i kick kick and kick...it finally starts so I ride it and get it on the road to see how shee is running and it acts as if something is holding it back it prolly wouldn't outrun a 400ex....... after that ride it wouldnt start no more checked for spark........NONE! so I get out the ole multimeter and check the stator and it comes up bad...So I call rickystator and buy a new stator...it gets here and I check it also and it comes up bad! I'm like WTF! So I start looking at the mutlimeter and turns out it was bad! I go buy a new one and check both stators and yulp they are both good! oh well...Now here the Problem! it can only be the COIL or CDI I already went through the wiring yesterday! The only thing is I cannot test the coil to see if it is bad or not...Me & RS already went through this even their new coils will show up bad if tested. Also there is no way for me to test the CDI So now it's hit or miss but I bet after I get it fixed it'll have damn good spark! Sorry to be so lengthy but just wanted to let you guys know the story, noone around here rides a banshee only 4 strokes! don't know what the hell to do.................

Snopczynski Posted March 28, 2007 Report Share Posted March 28, 2007 Did you put the RS stator on? Quote Link to comment Share on other sites More sharing options...
boonman Posted March 28, 2007 Report Share Posted March 28, 2007 You have 2 options, either get a buddy with a banshee, and swap his coil and/or CDI onto your bike to see which one may be bad, or buy new parts. Actually, there is another one, make sure all your grounds are good, and that your kill switch isn't faulty. Be careful about chaffed wires inside the harness, I know you mentioned you checked it already, but chaffed wires are sometimes hard to spot.....

fast500#12 Posted March 28, 2007 Report Share Posted March 28, 2007 check the plug caps. the resistors in there that go bad. Quote Link to comment Share on other sites More sharing options...
endofitall9 Posted March 29, 2007 Author Report Share Posted March 29, 2007 The RS Stator is on......The Harness had everything cut out of it boonman, only thing left is lights and switch but hell why it all stripped down i think I'm going to cut the kill switch out also and just get a tether and make the lights run constantly...there is noone around here with a hills banshee everyone has drag bikes with none of this shit on it most of them run the pvl I've been on the phone all day calling locla shops to see if they have a banshee that runs...nobody has a banshee....lol I called RS today and the guy said touch the leads of the multimeter to the coil terminals...I said ok liek the primary testing he said yeah, then he says if you see the readout jump then your coil is good, I said will it have an exact readout and he says no it will jump up and down and you wont get anything exact.....so that just crazy even if they are bad the readout will move..........I did talk to one of my buddies..that has a banshee but its been down for like 4 years now completely to the frame and cases split, he said he'll look for his coil but it will be a week before he could even get up to his banshee and look around for it....I wouldnt mind sending my coil to a trusted BHQ member so they could put it on their banshee and see if it works! This has been really frustrated...Even if my coil is bad it will be the 2nd one in 2 years..the I'll have had a new coil 3 years in a row if it is bad.........

blowit Posted March 29, 2007 Report Share Posted March 29, 2007 sent ya a pm Not sure why you cannot test that coil. If you really do not have someone to test it, you can send it to us and we will test it for you free of charge. You can absolutely test the OEM coil on the bench. Coils with resistive wires simply need the wires removed to test. All it is is a boosting transformer with a primary coil and secondary coil pack. The KEY here is wires!! Wires cause problems and indicate coil failure when you have a wire failure. You must remove the wires when testing to isolate the problem. Checking resistance in the wires, cap, coil, are all things that should be looked at. If you are using non-resistor plugs, it can overheat the secondary coil pack due to back talk from the plug. Similar to detonation only with AC current. It will increase your voltage in the coil and can cause dielectric breakdown in the laquer coating in the coil. This is our reason for good resistive caps but wires will do the same. This back talk is not seen in near the amplitude on the down side of the coil due to the coil bucking the voltage.

endofitall9 Posted March 29, 2007 Author Report Share Posted March 29, 2007 well Glad you chimed in on this you sound like you know your SHAT... see the thing I've learned about the RS Coils is, For some godforsaken reason they will not give you a reading...When I got this thing new I tested it, just as you would test your stock and could get nothing, the primary would just go off the wall different readings everytime and the secondary would you you no reading with the wires on or with the wires off, but when you put it on the bike sure enough it would run....just don't understand it....As for the plugs won't run anything else but a resistor plug NGK BR8ES... I'm going to try and get a coil to throw on to see if it will start but for some odd reason I'm leaning towards the CDI being bad. This will be the second coil bad in 2 years if it is but......When the first one went bad it had none of the symptoms that this problem is giving me. If in the case I cannot find a coil by this weekend jus to see if it will run so Iknow what I have to buy I will gladly send this one to you to get it tested....only thing I forgot to mention is when I did get this coil from RS last year I took it around to 3 different shops in the huntington area..to have them bench test it and everyone told me that RS sent me a bad coil.To make a long story short I threw it on the bike just to see if it would work contrary to all the testing and sure enough the banshee started right up......I can't believe it has been this difficult to diagnose the problem but most of this is due to lack of resources due to noone around me riding a banshee.......... thanks Josh Quote Link to comment Share on other sites More sharing options...

We generally use our custom coils but we have to mod some stuff to use them. I would like to take a look at the coil because if the coil does not read, it more than likely has a high voltage diode in series with the coils that must be energized to flow current. This can also protect the coil from feed back so that is not a bad thing at all. A diode is a one way valve for electricity but many high current and voltage diodes must be energized to be tested. IA, apply 10V to the primary coil and test resistance. Only good meters apply for this testing though. 10V is also a guess because it may need more but I think 10V would do it. The Banshee does not make that much at idle speeds. Brandon Quote Link to comment Share on other sites More sharing options...
