OK guys there have been a lot of postings about this problem, and a few good fixes. They all involve some fiddling with wiring, a topic that many are not comfortable doing. The cause is known to those of us who have posted fixes, the trouble has been finding a way for the home DIY Guzzi guy to make his bike reliable. I rarely feel that adding parts to a system is the best way to make it more reliable, but in this case it is. MPH has sourced the connectors needed to make a plug and play voltage supply relay kit available. Installation is as simple as can be , unplug your starter relay, plug in the harness, attach the removed relay to the harness, zip tie the OE removed relay to the supplied relay, and connect the 2 eyelets to the battery. We are using the well known Bosch relay and a Mini ATC fuse holder . In the rare event of a failure of any part of this system, you can unplug it all and be stock again in seconds. -Mike Haven
This kit looks like it will sell for about $40 shipped in the US. We have enough supplies on hand to make a few, but we are wondering how much call there will be for these. Any volume production will take a few weeks to get ramped up.
I'm sorry, but for the life of me I can't see why you need an additional relay. A plug and play fitment to replace the yellow wire to the start relay is certainly a good idea, but can be done just as well without the extra relay.
Brian UK please elaborate on your scheme if you would. My reason for the relay is the fact that the yellow circuit must be turned off when the bike is switched off. A direct connection to the battery results in a dead battery overnight. I am all ears for a better way to connect it, if you can share.
I have removed the yellow wire from the start relay and taped the end up. Then connected a new wire from battery positive to the vacant pin on the relay. QED. Having sourced the connectors to make a plug and play item, all you should need to do is run the three wires from the male connector to the female, leaving the yellow not connected, and connect your fused red from the battery to the remaining connection on the female where the yellow would have gone. This should copy exactly what I have done. It does not result in a dead battery. Remember the new red wire is connected to a normally open contact on the relay. Hope this makes sense.
Hey, if I was in any way a part of improving the product, it was my pleasure. That's what we're all here for isn't it?
However, I have to say that I have once had the problem return, and it blew the new inline fuse too. I took the starter motor off and pulled the solenoid. I found the plunger was quite tight in the solenoid, and there was a ridge at one end too. I cleaned that off, and put some light oil on the plunger (there was some dried grease there before) and all has been good since - so far.
