1987 Jag no spark

Hi, I'm new here and looking for some advise. I have a 1987 Jag 340 with no spark. I am interested in checking the primary ignition coil on the stator. This model has two different three prong connector which come from the stator. I disconnected the connector which leads to the C.D. Unit to test the resistence of the ignition coil. Does anyone know what the resistence should be? Thanks for any help:dunno

The first thing is to eliminate all the kills! Unplug the 4 way and test! Then put in a jumper wire across the brown and black, test!

Yeah, I already checked the kills. The machine came with a factory jumper for the throttle safety switch and I made another jumper for the kill switch. I got negative results so I went to the ignition power source, the stator, to measure the primary coil resistences. The Three pronged connection had a GREEN wire, a RED & WHITE wire, and a BLACK & WHITE wire. The measurements I had were as follows:

GRN to BLK & WHT 18 OHMS
RED & WHT to GREEN 170 OHMS
RED & WHT to BLK & WHT 140 OHMS

This seems low to me, I would have thought that the primaries should have had more resistence but it is only a 340 sided machine. Any thoughts are appreciated.

Did you do the teather switch? or the Carb switch? It is really best to start at the 4 way!

This year machine has no teather switch. The first thing I did was to use jumpers on the kill switch and the TSS. When that produced negative results, I pulled the three way and used a jumper on the brown and black wires, this also produced no spark. This is why I am checking the resistence of the stator. I also have a 1989 cougar and my next step is to swap some parts out between the jag and cougar, but I'd much rather just replace the primary coil in the jag's stator if the resistence is low. Any advice is appreciated.

Just an update, the jumper on the four way blk to brown produced weak spark. Any thought????

SUCCESS!!!!! I had a broken wire just up stream of the four prong connector. I had weak spark but it would not run, just kind of fart every few pulls. I checked to see if I had the four way plugged in all the way and then she started right up. I then started to wrap the connections, while the sled was still running, to secure with the harness to the wire loop and she died. Fifteen minutes later of wiggling the wires she started again. I probed each wire for continuity and found the break. A little solder and a little heat shrink and she will be fine. This broken wire nearly caused me to go mad.

You see, it can be anything! Thats why I always say to start with the 4 way! I had a litle water in that conector shorting things out once!
