I read Brian UK's excellent faq on the yellow wire mod to supply 12v directly and fix the non start issue. Looking at a bike from the right I can see 4 relays if I pull the rear right and look underneath bot left is a yellow wire bot right orange/yell top right brown top left red. Is this the yellow wire and instead of cutting it can I just just a inline crimp adding a fused wire from bat to improve the voltage supply? The yellow wire only has 1/2 inch showing so I guess we cut some of the loom sleeving back?

breva v1100 starter relay mod
- Thread starter nel
- Start date
Hi Nel,
I think if you put 12volts permanently onto the yellow wire the Number plate Light will be on all the time also a feed goes to the Left dimmer switch and Key operated switch. On my Breva I was able to use a pin, unhook the connector inside the terminal block and slide the yellow wire out and insulated it. I then inserted a spade connector into the terminal block and connected it via a 15A fuse to the battery +ve. Use a meter or lamp to double check you have the correct relay/wire
Cheers Kevin

Relay positions are in the 1100 Breva service manual ( the PowerPoint file converted to PDF) in the download section. However, confirm that you do have the correct relay as on my bike, it was in a different position.
thks for the replies guys. At first glance coundn't find anything in the service manual about the relays apart from the circuit diagram which is to small to read. The back right relay seems to be the only one with a yellow wire attached. Snowed over night so I'm waiting for the temp outside to warm up (no garage) before I attempt the fix. Did 80m the other day -2 thank god for heated gear. Had to carry my jump leads cause the wiring switches a bit corroded on my b11.

See page 81 in the general service manual you can download here https://www.guzzitech.com/downloads/ca ... -1100.html It identifies the locations of the relays.
Go to the "tech" section on here, "electrical" "Carl Allisons Wiring Diagrams" "2005_Breva_1100.gif". The wiring diagram here is much easier to read.

thanks again guys. It would appear my breva is different to the relay layout page 81 in that my relay is rear right not front right. The yellow wire switches to 11.37 when you turn the ignition and you get a clunk from the starter motor then nothing. Charging the battery a bit starts it but charging is very short period I already replaced the battery once sometimes you gotta do a few things yellow wire add and a 3rd battery to get it reliable.

old thread but very important! I am getting the click from the Starter/Solenoid not the relay.... What are the possibilities? I am worried it could be the starter. Does the relay fix help with this problems as well??? Thanks in Advance.
This is a common thing. SEARCH startus interruptus or Hard start relay
You can order one from MPH Cycles

1st check you have a decent battery, get it load tested then make sure all the connections are clean and tight.
It is possible the starter has gone bad. Remove it from the bike and bench test it. While the starter is out, clean the ground cable connection behind the starter cover. I had to replace the starter on my Breva a couple years ago. The Valeo starter isn't the best design in my opinion and is not worth rebuilding. If it is bad, replace with new. That said, the relay fix is needed for all CARC bikes.

The starter relay on the B-V1100 doesn't have a "yellow" wire.... I have searched for the correct one and can't find it. Also emailed Kim at MPH cycles with no response. Sorry, stuck out here in Hawaii! Very few MG's here. Thanks!
Are you looking at the correct relay?
Remove the starter cover and disconnect and isolate the wire that goes to the spade connector on the solenoid so it doesn't make any contact and blow a fuse. Turn your ignition key on and place a finger on a relay top. Press the start button. If you feel it click, that is the starter relay. If not, cycle ignition key and try a different relay. Repeat until you find it.

after some more thinking.... It may have been the fuel pump relay. But when I removed the relay there was no power to the starter. I will look again later this week. Bike is not a my house. Do you have a picture of the location?

This is on my 2006 Breva 1100, The 1st photo shows the position of the relay, this is looking from the back of the bike to the front on the RHS,
it is the last relay on the inside under the tank.
The 2nd photo is the relay removed and looking at the underside, you can see my yellow wire removed (insulation fell off) and a red wire connected in its place (pin 3) that goes via a 15A fuse to the battery + positive.

You can also buy the connectors on tinterweb.
That allows you to modify to your hearts content without cutting the loom.

Bingo! Thanks... I was looking at the wrong relay. Never heard back from MPH Cycles so I ordered a lead with fuse online and will install this weekend. Thanks to all!
