Here again is the difference between an early 1100 2 Valve and the later 1200 4 Valve
Here is the 2006 just a single Start Relay fed direct from fuse "C" (strictly speaking through 2 fuses in series)
[You must be registered and logged in to see this link.]
I suspect this didn't give too much trouble but the wire from relay to solenoid is far too small so change it out for sure.


And the 2008 downstream of the ignition switch from fuse 2
[You must be registered and logged in to see this link.]
This bike has 2 Start Relays but now the start relay is fed down stream of the ignition switch through a lot more wiring
Martin's video right near the start indicates what happens by the light going dim, his headlight is fed from the weak yellow wire that feeds the Start relay.
I believe the second Start Relay was added to later CARC bikes to counter the first relay dropping out on under Voltage, this is just at the very start while the
solenoid is pulling in to close the main solenoid contact. If it manages to close the cranking will be normal.
Again the wire from relay to solenoid is too small, change it out.

I am fairly sure if you have modified the 4 Valve with a direct fuse you can unplug the second relay, I don't have a 4 valve to play with so I can't try it.

Question for Roy.

The yellow & black feed for the Light Logic Relay (6), the GPS feed (7), and the Left Hand Light Switch (9) are connected to connector "L" on the generator (27) whilst the rest of the bikes electrics including the battery are fed from connector "B" on the generator.

I'm assuming the the "generator" is actually an alternator plus diode matrix combo, but what are the separate feeds from the "generator" connected to inside the "generator"?

I'm guessing that perhaps these feeds are designed to come alive once the motor is running to reduce the initial load on the battery while starting, but how is it achieved? scratch

Sorry Dave, i'm not really sure but I think the green/black wire from the alternator is feeding the light relay and also the top 2 or 3 fuses.
I looked at the Norge drawings as well.
The alternator must include a Voltage regulator, but I don't know much about it, never had to look at mine.

Hi folks, I am another convert to this fix for the starting problem. A typical day for me would be a number of button pushes followed by a click and then nothing. This would often repeat over and over, of course other days it would not miss a beat and start first try.
This week I ran a fused wire from the battery to the relay and another to the stater solenoid, like magic the bike has not missed a start once. Fingers crossed while touching wood!

I cannot express enough thanks for the great help here on these pages, I am electrically inept and a visual learner so after reading about the fix it was great to see the video which gave me the confidence to have a go, job done.

Now I just have to work out why I have developed a tiny oil leak after an oil and filter change. The drip is from the area around the filter. I am positive I cleaned the face correctly but the evidence would appear that I may have been more thorough.

I just wish I lived closer to Pete, then I could let someone that has clue take care of GRiSO!

Are you sure the old gasket came off with the old filter? They quite often stick to the filter seat up in the 'Pit' and then if another filter is installed you'll get a leak.

Yeah I took a look and cleaned it with a cloth, I think I got it all. Always appreciate your help Pete. Pete if i attempt to remove the filter and clean again will I make an almighty mess and loose all the oil?

Nope. You'll loose a bit but not a lot.
