Spare Relays

[bikelee]

I want to carry some spare relays in my 2003 Rossa. Are all the relays the same ? Where should i purchase them ? The bike is running well, I just want to carry some spare ones just in case. I know they fail at the worst possible time. Thanks, Leon.

I carry spare 5 pin relays and they will do for the 4pin relay slots too. In fact I think all mine are 5pin now.

As AndyH says, they are an ISO standard Micro-relay, made by many manufacturers

 

Unlike most other guzzis these bikes need a full complement of relays to operate.

The middle relay called the sidestand relay but is actually the Neutral relay can be removed and replaced by a short length

of wire stuffed in the socket to short out pins 30-87.

The headlight must be operational for the charging system to work which requires the first two, Start & Headlight relays. 

The rear two relays are connected with the ECU, they are essential.

Faced with a bike that refuses to start first thing I do is listen for the fuel pump when I turn on the key

Does it crank, if so the power is getting all the way past the Ignition switch, Sidestand (Neutral) switch and Run (Kill) switch

Give all the relays a little wiggle, this scrubs up the pins in the base, perhaps swap the relays from position 1 & 2 for 4 & 5

 

Heres a simple schematic I did years ago, it applies the early FI models, the Lemans as well as V11 Sport.

It's not easy to tell if a relays working, they just make a quiet click and which one is clicking?

The first project on my V11 Sport was to add a light to each relay, it takes all the guesswork out of it.

I have been touting this idea for years but I don't think anyone has followed suit

This is the very best answer and source (in North America) from Kiwi_Roy posted in Relay Replacement.

order good relays from Pyro Dan,

The relays from pyroDan are shockingly inexpensive and I don't recall any failures reported on the GEI he currently has on offer.

 

The link to the Kiwi_Roy post is for OMRON which are likely "better" relays, but may be overkill and at least double the money.

By the way Lee.Most of the problems come from the original relays from the factory.Most people who have changed them,which is most of us,haven't had a problem since.

The next most common problem is the connection a the base of the relay panel.Once those are sorted it's rare that you will have issues.

Not saying it wouldn't be a good idea to carry a couple,but like a tire repair kit,if you have one,you won't get a flat.
