Thanks to all you guys commenting and offering suggestions.
Replacing the 15a fuse with 3 purchased from the local motofactor just resulted in a blown fuse every time so out of desperation I folded a piece of 5amp fuse wire and twisted it around one of the blown fuse blades then across to the other then pushed the fuse back. In theory that would give a 10amp rating plus its "crude" over current rating so its probably at 18 to 20amps and would be a bit messy if it blows so its not ideal and a temporary fix and I'm reluctant to do the permanent 20 amp fuse fix. My predicament now is identifying the start relay and the colour of wire to cut, is it the only relay that clicks when I first turn the ignition on and then clicks again when the instruments have cycled through the check sequence which then allows me to start the engine? if so the wire colours are: 1) Orange/Green 2) Red and in a lighter gauge wire 3) red 4) white The other 2 relays only click when the engine is running and the wiring colours are Green/Black Brown/Black with a black wire and a green wire in a lighter gauge on one relay then Orange/Yellow Brown/Pink with a yellow and a green on the other. I guess as you read through this you will realize I am a little nervous on which wire I should be cutting to do the hard wire mod to the battery as the colour coding on my bike doesn't seem to match descriptions given that I have seen so far. So once again could I please ask for help as its only easy when you know how. Mike |

Hi Mike,
Had exactly that problem on my Breva 1200 Sport a month or so back. The instructions at the beginning of this topic are pretty good in terms of which wires need messing with. My starter relay was to the right of the bike and in front of the battery area. As I recall there are one or two others very similar relays. If you take the small side panel off here you can get a better look and the one you are after is (I think) the only one with a yellow wire. If you pull the relays upward they slide off the bracket (Rubber holder comes too) - and you can see what's what. I bottled cutting / rewiring anything as I have messed up wiring / crimping before and ended up chasing faults around. My solution cost a bit more (£30 ish) - but there are a few folks out there selling wiring kits which just plug into the relay connector and the jobs a good un. I think the sellers of these things are a bloke on the WildGuzzi forum (cant remember exactly) and MPH Motorcycles (Texas). I got mine from MPH for no particular reason - but it seems to have cured it. Hope that helps.

Thanks for that guzzigraham and I thought I should post an update.
After sending my last post at 10:34 today I decided to investigate further so removed the starter and solenoid assembly so I could positively (no pun intended) identify the colour of the cable to the solenoid. While "spannering" I also cleaned up the earth connection to the engine as a precaution. I now realize the yellow wire is the one to cut and as per instructions I wired from the + on the battery to the cut yellow on the relay plug. Feed from the battery is via a crimped lug, a 15 amp inline fuse and connected via a female to male spade connection on the now "short length" relay yellow. The cut end of the yellow from the loom also has a female insulated spade should it ever be needed. Spare inline fuses are now stored on the bike "just in case" and in the unlikely event of the one fitted blow it will be uprated. So thanks again for the offered help/advice and my apologies for any boredom it may have caused for you guys that have been there done that. Mike

It's Todd from the Guzzitech forum who made and sells the plug in mod. The start relay clicks when you press the start button, not when you turn on the ignition. It's the yellow wire.
A temp repair for the 15amp fuse blowing is replace it with a 25 amp one. |

Thanks for that Tod, once the mist on my brain had cleared, as you can see from the post just before yours I believe I have the problem sorted.
I'd measured the voltage at the relay yellow on start up and found it initially went down from 12:6 to 6:4 returning to 13:6 when running and on normal idle. I've not checked it again yet since the "battery to relay" mod but I'm assuming its higher. As a matter of interest would a code normally need to be entered when disconnecting the battery. I bought the bike last September from Newcastle Motorcycles and they told me at the time of purchase any code required is likely to be all the zero's. I cautiously made sure the loom to battery connection was maintained when connecting the lug to the positive terminal but I wonder because the display asks for a user code when starting up. |

You should not normally need a code when reconnecting the battery.

How old is your battery ?
I replaced mine with a nice gel motobatt with higher cranking speed Electrics modification is one feed fused to one wire (yellow)cut & well worth doing. Hope your problem is fixed Ps I changed my battery and no code was asked for......I don't have one either so guess I was lucky Edited by magwa - 11 Jul 2017 at 10:22 |

Obviously i'm still suffering from a little "brain mist" my reply saying thanks to Brian UK should start by reading "Thanks for that Todd reference",

My Bellagio seems to have fallen victim to this today. Not entirely surprised as last week, just when I had filtered to the front of a line of traffic in rush hour, I had a 'Service' light appear then total electrical failure. Bike died, no dash, no lights, no nothing. Did a quick (and only marginally embarrassing) push to the side of the road and fiddled about for a while with replacement fuses to no avail, until I re-tensioned the battery connections - and on came the lights. Thanks to Guzzi for the toolkit which did the job!
Yesterday I noticed that the battery was showing under 12 volts at idle on the dash while sat at lights, up to 14+ when revs were up, and this morning the service light came on and - click no crank. Battery voltage shows 12.1v with ignition on and engine off. In my case, i'm fairly sure that the battery is dying, because it's the original (10 year old!) unit, albeit always trickle charged. I'll check it tonight and swap in my new spare, which has been sat on the shelf waiting for this moment for almost 2 years! |

10 years must be a record for one of those batteries.

10 years is doing well for any battery ..... depending on your usage and battery quality 2-5 yrs is usual stretching it to 7 yrs .....

Yes, good going. The bike's only done 3.5k though so it had an easy life before i bought it.
However the karmic balance has been restored and in return for my long-lived battery i've just been rewarded with my second puncture in 2 months. Happy days!
