Now, no spark?

newelly,

The resistance between either plug wire and the primary winding should be infinity. If you are reading 15 K between either plug wire and the primary, then that would indicate a partial short from the primary to the out put (secondary) winding.

If you are using the high range on the Ohm meter, keep in mind that it will also read the resistance between one hand and the other on your body, so be sure that you are not touching the tips of the meter when you take the measurement.

Measure the resistance again between either plug wire and the primary.

I had the ohm meter set at 20k and put one of the leads into the L plug cap and the other into the R and got 1667 reading on the meter, is there a way to pull the wire that comes with the 14-0901 kit from mikes? Does anyone have a picture of how to re-do the fuse box or how a good fuse box is supposed to look

Heres a pic of a coil, the primary coil is where the 12 volt wires go, the secondary coil is what powers the spark plug. As Pete said, measure resistance (ohms) between primary input & secondary output!

a picture of the actual coil would be a little more helpful...

yeah, no problem mate. Don't worry about saying thanks! Rolling Eyes

Anything else I can do for you?

sorry about that... I reall do appreciate the help as that I am new to this whole deal (electronics)... thanks again for the help I will let you know of any changes as they happen...again if any of you have a picture of the coil would be much appreciated... thanks

newelly,

There are pictures of the coils on myn site, www.yamahaxs650.com . I am still concerned about your reading between the plug wires and the primary terminals. Should be infinity.

No worries mate, pm sent. Let us know how you get on with that.

newelly · Posted: July 26, 2009, 6:48 pm Post subject: Re: Now, no spark?

so here is what I have after I pulled the coil... There are 3 pics one of each cap and the other is of and the ends of the multi into the plugs wires... also when i put the leads to the re/white set at 20DCV i was getting a reading of .30 roughly from each wire with the ignition on, i did it the other day and got 12 or something like that... so what does all this mean?? Thanks agin fellas...

wow, no help yet... that is odd...J/K but seriously can anyone help me?

Well, here is a copy of what I posted for you on the garage......

Anyway, this is not rocket science. When you turn on the ignition switch and the kill switch, battery voltage should be at the red/white wires, period.....a reading of .3 volts is either a problem with the method you are using to measure the voltage, or you have a blown fuse, bad contacts in the ignition switch or kill switch or a loose connection.

I think it had been suggested earlier that you run a jumper with a fuse directly from the battery positive terminal to either of the red/white wires with the kill switch off. That test will determine if your problem is in the wiring of the bike or the ignition system.

I think that the spark tester that you are using may not be working properly with this system, so here is a recommended test procedure to test for spark without having to turn the engine over:

1. Use a voltmeter and check for battery voltage on each of the red/white wires with the key and kill switch are turned on.
2. The dual output coil has to have both spark plug wires connected to a spark plug at all times.
3. To test for spark, connect one of the spark plug wires to a spark plug that is grounded to the engine. Leave the other spark plug in the engine, connected to the other spark plug wire from the coil.
To test for spark without having to turn the engine over, do this procedure:
1. Remove the PAMCO rotor.
2. Remove the locating pin in the advance rod.
3. Reinstall the rotor, but without the pin.
4. Replace the nut holding the rotor on loosely. This will allow you to spin the rotor to produce a spark without having to turn the engine over.
5. Connect one of the spark plug wires to a spark plug that is grounded to the engine, but not installed in the engine.
6. Make sure that the other spark plug wire is connected to a spark plug in the engine.
7. Turn on the ignition switch and the kill switch.
8. Spin the rotor while looking at the gap in the spark plug for a spark.
9. Turn off the kill switch and the ignition switch.

I have a question for you I know its a little late asking this but is there a specific positive and negative on the 17-6822 coil, and does anyone have a wiring diagram for installing the pamco set-up... I am thinking that I blew a fuse somewhere and I want to know where the fuses are on a 79, again remembering that under the seat I have 2 of the 4 fuses that were connected with fuses and two sets were just twist capped by the previous owner... thanks again, at this point I am almost ready to have my dad come and help me install a new harness...thanks again...

sucess!!! I have spark on both sides and everything seems to be good... I have yet to attempt to start it as that one of my fuel line is leaking fuel...will post as soon as i can.... THANKS AGAIN TO EVERYONE THAT HELPED!!! you guys are awesome..

Shifted from electrical forum at pumps (original author) request.
If anybody has any concerns over this, feel free to contact me about it. Cheers

newelly · Posted: August 4, 2009, 9:33 pm Post subject: Re: Now, no spark?

again I just want to say thanks to everyone on the board for helping me get my bike running... now keeping it running is another story... again thanks to everyone for all of your help, Pete great product...
