Trigger Point Conumdrum

Hi Peter,

yes the diagram I posted is in sequence of firing. But colors are selected by oscilloscope, have nothing to do with wiring harness.

When you have wet spark plugs, then either they are dead (swap with new NGK ones) or ignition does not operate as it should or mixture is far too rich. Spraying start pilot will then not help.

Any issue with this - tested the pin 18. At the top relay I am getting over 12 V and at the other relay (directly below) I am getting about 9.5V and this is the same reading I am getting at the ECU.
Thanks
Peter

Hi,

pin 18 should show 9...12V while cranking starter. I do not know what you mean by 12V at top relay. If you talk of cold start valve relay, that has nothing to do with it.

Hi,
These are the 2 I tested. So 9.5 volts should be fine?
Thanks

9.5V is fine for ECU. I cannot believe that line 50 from starter shows 9.5V on relay 4, 12 on relay 2 and then again 9.5 on ECU. Or maybe I do not get you right.

Hi all (especially Volker),
I promise this will be my last 2 questions (for awhile at least) and then I will leave you alone.
1/. On the Trigger point actuators that touch the cam - does a short length (say 1.8 mm compared to 2.4mm) increase the injection amount (points are closed longer and therefore injecting more fuel) or is it the opposite?

2/. What would cause the spark at the sparkplug to jump to the body of the plug and not the tip?

Regards (and thank you)
Peter
