any ideas?

[BB]

No probs, glad my new rack came in handy! Be good if my bonnie's intermittant fault was found too!

[Dabz]

yeh that's the next challenge for our forum tech heads hehe

[Dabz]

well Paul fitted the new solenoid and it still doesn't start unless you short it with a screwdriver, main headlight also doesn't come on (only sidelight)

any further ideas?

I have a friend on the Aprilia forum who is the absolute whiz at these sorts of things........I'll drop him a line. He talked me through fitting a Datatool 3 over the phone.

You may remember him, Forbes Cowan, a contestant on the Worlds Strongest Man - Scottish man mountain.

This is what Forbes has replied with...................

TROUBLE SHOOTING
Starter motor will not run.
Step 1
1) The transmission is in neutral. Grasp the clutch lever, turn on the ignition switch with the engine stop switch in the “RUN” position.
2) Listen for a click from the starter relay when the starter button is pushed.
Is a click sound heard?

YES Go to Step 2.
NO Go to Step 3.

Step 2
1) Check if the starter motor runs when its terminal is connected to the
+ battery terminal. (Do not use thin
“wire” because a large amount of current flows.)
Does the starter motor run?
YES • Faulty starter relay
NO • Loose or disconnected starter motor


Step 3
1) Measure the starter relay voltage at the starter relay connectors (between Y/G + and B/Y -) when the starter button is pushed.
Is the voltage OK?

YES Go to Step 4.
NO
• Faulty ignition switch
• Faulty engine stop switch
• Faulty clutch lever position switch
• Faulty gear position switch
• Faulty turn signal/side-stand relay
• Faulty starter button
• Poor contact of connector
• Open circuit in wire harness


Step 4
1) Check the starter relay.

Apply 12 V to
terminals inside multi plug on the solenoid use the two terminals closest to the heavy bolt connectors, now for continuity between the positive and negative terminals using the multi circuit tester. If the starter relay clicks and continuity is found, the relay is OK

Measure the relay coil resistance between the terminals using
the multi circuit tester. If the resistance is not within the specified
value, replace the starter relay with a new one.
# Starter relay resistance: 3 – 6 [ch8486]

Is the starter relay OK?

YES Poor contact of the starter relay
NO Faulty starter relay


NOTE:
The starter motor runs when the transmission is in neutral with the side-stand up or down, but does not run
when the transmission is in any position other than neutral with the side-stand down.


2) Check the side-stand switch. (!7-17)
Is the side-stand switch OK?

YES • Open circuit in wire harness
• Poor contact of connector
NO Faulty side-stand switch

I've seen Forbes on the telly many a time! Never had him down as a biker!

[Dabz]

thanks for that mate we've also had a heads up that it's probably the side stand switch because it's a common fault on this bike, so I think that's what he's trying today...I'll keep you posted!
