Re: GPZ500 No Spark!

Hi

Thanks for the suggestions/opinions.

Having retested the coils 'in situ', I am getting a spark - but it is
weak. So, I assume this means that all the circuit components are ok.
But why is the spark weak? Could there be some sort of earth fault
dragging current away from the coils?

FB :- I checked the sidestand switch, got open circuit/closed circuit
when raising/lowering the sidestand. (Although the wire colours in my
Haynes manual 2052 for teh EX500 D UK model differ to that on the
bike.) So happy with the side stand.

Ted :- Yep, ordered a factory manual for the bike from Bournemouth
kawasaki. Only 27 quid plus posting. So waiting on that. I collected
the coils today from the shop, and have spent 15 quid on a length of
fresh HT lead and NGK plug caps. (They simply screw on.) I did it after
hooking the coils back on the bike and just getting a weak spark (ie.
hairline thickness, watery blue). Nevertheless, all this means the
pulse generator is giving the signal to the IC igniter unit.

oldgeezer :- damn right it best not be the igniter unit - all this is
justice for me being too lazy to cover the bike up....

My plan now:

1. Recharge battery.
2. Hook coils / new HT lead etc up and see if there is a better spark
against engine case.
3. Drain carb float bowls.
4. Fresh fuel in.
5. Put plugs into bike and try full starting.

Basically I am hoping that the spark is weak because the HT leads and
plugs are old - the HT leads were not very flexible, and I have been
pulling the plugs out alot a while back as I had the top end off.

Cheers, will keep you updated if I find any other stuff out.
