I have what I can only describe as a "sputter". When cruising the bike spits and sputters and recently No.4 cylinder keeps fouling out. I have replaced the wires, plugs and caps. I took one of the coils out just to take a reading and according to the service manual, I am supposed to have a reading of 3-5 ohms on the primary and 30-50 ohms on the secondary. I put the multi tester in and got NOTHING. Am I missing something? Tried searching and couldnt seem to find anything about sputtering or anything on my bike. Anyone have any Ideas or suggestions? Need to get this thing running asap.

Do you have the wires disconnected from the primary terminals?
If you don't, you may not see the correct readings.
For the secondary side resistance, read the book again, you should be seeing 30-50k ohms. That's THIRTY TO FIFTY THOUSAND ohms.
Measure that from one spark plug cap to the other.

On an '83 750 (the one in his signature), there are no points.Originally posted by chuck hahn View Post

Yea sorry guys I just realized I didnt put what bike. It is an 83 GS750E. Also I forgot the put the "k" in the 30-50. I took the entire coil out and disconnected it. I get zero all the way around.Comment

3 to 5 ohms isn't much. Your meter should be set at ohms x 1Comment

Do you have OEM plug caps? Aftermarket caps may have about 5K less ohms on each cap meaning your reading of 25K might be all right if you have the aftermarkets.1983 GS 1100 Guided Laser

No, Im using NGK caps (5ohm) I believe they are VD05F's. Going to check the other coil to see what its at and go from there.Comment

took the caps off and measured directly from the wires and got 15k. Looks like Im looking at new coils. Anyone out there have any good suggestions????Last edited by Guest; 06-12-2011, 10:25 PM.Comment

also, still no reading form the primary side on either coil....Comment

Again, you are missing the K. Those caps are 5k ohms.Originally posted by smarzinski View Post
In stock form, it is measured from plug cap to plug cap. The plug caps have 5k resistance, so if you include both of them, you would be reading 25k.Originally posted by smarzinski View Post
When you say "no reading", are you reading Zero (as in 'direct short') or OL (as in 'out of range' or 'open')?Originally posted by smarzinski View Post

My stock plug caps measure 11K ohms each approximately. If you include 2 of those plus your 15K ohms wire to wire measurement you would come up with 37K ohms. I don't think your 25K ohm measurement cap to cap with the NGK's is a problem.
On my coils, to measure primary, I have to make sure to get a real good contact with my cheapo meter. Are you sure you have the meter set in the proper range to measure ohms instead of K ohms?1983 GS 1100 Guided Laser

When the multimeter is not connected to anything and turned on it reads "1". When I connect the contacts to the primary side of the coil it still reads "1". Tried every ohm setting and get the same thing.Originally posted by Steve View PostComment

Got some new leads for the meter, got a reading of 4 ohms on the primary side. My caps tested to 5k ohms each and the coils without the caps tested at 15k ohms. If im understanding this thats only 25k ohms.Originally posted by 1948man View PostComment
