1982 Aspencade no spark

Post by frodeem » Wed Feb 14, 2018 5:07 pm



Hi,

I did the Neon coil swap to my bike and I am not getting a spark. I have new spark plugs, new spark plug leads, and new boots.

Please bear with me as my knowledge of electrical systems is very limited. I am sure I will ask some stupid questions. Sorry in advance.

Question about the Neon coil:
1. What should the primary and secondary resistance be for the Neon coil?

I am following the service manual troubleshooting guidelines and have some questions about the ignition circuit.
1. Measure cranking voltage - This is where the screw up is occurring I guess. I am getting a negative reading here. How is that even possible?
2. Measure voltage drop at coil - same, I am getting a negative reading.

Primary circuit check:
1. Check pulse coil resistance. Should have 530 Ohms ± 50 Ohms - I got a reading of 497 and 487 (the temperature in my garage was 25 degrees and the recommended temperature listed in the manual is 68 degrees).
2. Check pulse generator for short to ground. Should be infinite - My measurement reading was infinite.
3. Check for battery voltage at spark unit B/W wire. Should be approximately 12V. I checked both spark units. Both check out at similar voltage 11.80 to 11.95.

I am a little confused by this point. Of course my knowledge of a motorcycle is limited so I would really appreciate your help with this point. My question about this point is that they want us to attach positive probe of a voltmeter to the blue/yellow wire in the six pin connector and the negative probe to ground (bike frame). They then want us to turn the ignition on. What am I looking for here? What is the recommended reading? They immediately jump to testing the 4 pin connector plug and want us to ground the white/blue terminal. For this they do tell us what the reading should be. This is confusing because then what is the point of grounding the blue/yellow wire terminal in the six pin connector in the first place?

Just be sure you connected the coil correctly, the center terminal is the hot wire, make sure you are getting power there, the yellow will go to the front terminal and the blue to the rear. Had someone else make the mistake of putting the hot wire to the front terminal.

I got the center terminal correct. Maybe the front and rear terminals are switched? I'll switch it back and test. Thanks

That would only make it fire 180 out, it would still make sparks.

Looks like you failed to read the last 2 lines in test correctly. They didn't jump to testing the 4 pin PG connector, it is part of the test.

Let me see if I understand what you are saying - even if the terminals are switched it should still not stop the coil from making a spark?

I am getting a reading of 11.7k Ohms on the secondary and 1.5 Ohms on the primary.

Yes you understand correctly. I have no memory of what the ohm value of a neon coil is. If you reconnect your old coils do they spark?
