No spark ?.
Hi guys,
Just been out to start the RT. It turned over but won't fire. Last used about a month ago. Battery is good, plenty of fuel in. Took a plug out & turned it over with it touching the cylinder head & can't see a spark.
Any ideas what checks do I need to make ? 1996 1150.
Many thanks
Mick

Re: No spark ?.
Has the plug on the other cylinder been checked for a spark, this may help to diagnose whether the problem is common to both cylinders or not.Mickthecat wrote:Took a plug out & turned it over with it touching the cylinder head & can't see a spark.
Is this the Bike in question.

Hi David
Thanks for your reply
Yes that's the bike. No spark to either side

Re: No spark ?.
Probably the ignition sensor has packed up. Lives in the bottom of the front engine cover and over the years can suffer from corrosion.

Re: No spark ?.
So it looks like a problem which is common to both cylinders.
I see from this thread, http://www.1200rt.com/index.php/topic,1350.0.html, that you have changed the Hall Sensor.
My understanding "Google" is that the Hall Sensor has two Sensors (Top & Bottom), one which triggers the Ignition & one which triggers the Injection.
How about the Ignition Coil, this pdf. Document http://advwisdom.hogranch.com/Wisdom/oi ... ensors.pdf shows how to test the Coil & Hall Sensor.
Is the wiring/insulation in good condition & are all connectors clean, something "Going to Earth" may kill the Spark.
From the Reg. No. the Bike is a 1997 R1100RT.

Re: No spark ?.
Yes I replaced the HES with one from Motorworks ( although it was a used one ) & all has been fine so far . I'll check the coil & wiring tomorrow. Are there any electrical connectors in particular I should look at first ?.

Re: No spark ?.
I believe that if an Injector is removed, the HES can be checked to see if it is sending a signal to the Injection System.
I suppose the first place to start with the wiring/connectors etc. would be to check anything related to the Ignition System.
Is the Bike garaged or out in the elements.

Re: No spark ?.
Its garaged. However the last time it was out was in a downpour. Not sure at all if that'd have any bearing ?.
Thanks

Re: No spark ?.
Moisture & electricity don't mix together very well, any breaks in insulation may cause the current to arc against other metallic parts of the Bike & "go to ground (earth)" before getting to the spark plug.Mickthecat wrote:However the last time it was out was in a downpour.

This may sound a little odd, try starting the Bike in the dark & look to see if anything is arcing against the frame etc.
Protecting the electrics with something like ACF-50 which dispels moisture, but conducts electricity may be helpful.

Got the plastics off & pulled the injectors. There's no fuel passing through them when the bike is turning over. It's priming ok.
Had a look at the wiring & there's nothing that looks out of place. Is there a way of testing the coil itself ?

Mick
Re: No spark ?.
When you switch on can you here the fuel pump start up, just a quick wearing noise. If not then it could be that. Its in the top left of the tank. They can also suffer from corrosion.

http://www.2wheeltours.hashsg.com/index.php?topic=193.0,
http://advrider.com/index.php?threads/h ... or.688232/,
they both suggest that if there is no spray/squirt from the Injector, then the HES is u/s.
