Newcs222 Posted January 11, 2014 Report Share Posted January 11, 2014 I own a 1987 Banshee. The bottom end rod bearing gave out on me so I decided to just buy a complete motor, something newer. I got a motor from a 2005 Shee and slapped it in the frame. I noticed the stator harness was different so I swapped the stator from my 87 motor. Put oil, anti-freeze, and fuel in and kicked the shit out of it. Pullled a plug and found I was getting no spark. Tested the stator and got all the rights resistances. Tested the coil and got .6 ohms on the primary side and 5.6k ohms on the secondary(plug cap to plug cap). I have tested the voltage out of the stator and i get around 3 volts between the yellow and black wire when i kick it over. Do you think its the CDI box at this point. I don't have a spare to test with and don't want to buy a new one if thats not the reason. Also when i had the motor out I spray painted the frame but didn't take any of the components off, just tapped them. I don't know what to do next. Any suggestions? Thanks. By the way the Tors has been removed. Quote Link to comment Share on other sites More sharing options...
uman1030 Posted January 11, 2014 Report Share Posted January 11, 2014 sure you have a good ground since you said you painted frame? make sure stator poles are clean? check pickup gap? Quote Link to comment Share on other sites More sharing options...
Newcs222 Posted January 11, 2014 Author Report Share Posted January 11, 2014 Where is the engine grounded to the chassis? I may need to take the engine bolts out and sand the mounts down? Ive just tested the ignition switch and it's good. I'll check the kill switch next. How to I check the gap? Quote Link to comment Share on other sites More sharing options...
uman1030 Posted January 11, 2014 Report Share Posted January 11, 2014 Your pickup coil gap should be set at .017 on both nubs. CDI ground is near cdi and there is another ground near Coil. Engine grounds are the bolts. http://www.dfn.com/agservices/elecfaq.html has all the info on the electrical system and testing. Quote Link to comment Share on other sites More sharing options...
Newcs222 Posted January 11, 2014 Author Report Share Posted January 11, 2014 How do I measure that. The gap is so small. I've got the cover off. I measure 3 volts on the yellow and black wires from the stator when I kick it over. Does this sound right Quote Link to comment Share on other sites More sharing options...
lastnline75 Posted January 11, 2014 Report Share Posted January 11, 2014 Thickness of a business card will be close if you dont have a set of guages. Just slide a busineds card in there an adlust the gap. Sent from my SCH-I545 using Tapatalk 2 1 Quote Link to comment Share on other sites More sharing options...

It was way too big. Could have fit 3 cards in. But I still have no spark! Any other suggestions? Quote Link to comment Share on other sites More sharing options...
Newcs222 Posted January 11, 2014 Author Report Share Posted January 11, 2014 Do you think the cdi failed due to the rod bearing giving out? The right jug on the older motor had pieces of bearing welded to it. Quote Link to comment Share on other sites More sharing options...

Mechanical failure wouldn't effect electrical components like that. test the on off switch and key switch if installed for continuity. if key switch has been bypassed make sure the splices are good. did you check the coil ground? and make sure coil wires are plugged in and making contact.

Ive done continuity tests on both switches. They're good. I don't see anywhere to ground the coil. Is there supposed to be three wires off the coil? Its got a black wire that runs into the harness. Its taped up pretty good. Is that the ground for the coil? Where does that ground at? Quote Link to comment Share on other sites More sharing options...
uman1030 Posted January 11, 2014 Report Share Posted January 11, 2014 have you tested the orange coil wire while kicking it over to see if you get any power to it? did you paint the frame under where the coil bolts in? i know you said tors was removed but is the box unplugged?

Okay i have spark now. I had to take the wiring harness apart and re-wire it. It had a bunch ob butt splices i got rid of and soldered. Now my problem is it won't start. I've been kicking it over for the past 2 hours and nothing. Flooded it for a bit. Any ideas. I will probably try and pul it behind my truck if i have to. The only problem with that is a live in the city. lol. Quote Link to comment Share on other sites More sharing options...
lastnline75 Posted January 12, 2014 Report Share Posted January 12, 2014 Dont pull it with a truck. You prolly fouled the plugs. Put some fresh plugs in it an see if that helps. Quote Link to comment Share on other sites More sharing options...
Newcs222 Posted January 12, 2014 Author Report Share Posted January 12, 2014 I had brand new plugs in at the time. Pulled then out and gave it a few kicks. Dried the plugs off and tried to start again. Still nothing! My plugs only seem to have a weak spark. And they don't spark everytime. Where is a good place to run a piece of wire to ground the case to the chassis? Quote Link to comment Share on other sites More sharing options...

Mine just did this weak random spark shit and it was the plug wire and caps. Changed them and bam we were back in action Quote Link to comment Share on other sites More sharing options...
