Go to your nearest automotive parts store and ask for a 30 amp 5 pin relay. Take the old one with you to show them and avoid Confusion. Those things are as common as nails on automobiles for the last 30 years.

They use nails to put autos together????

 

The relay next to the solenoid is the flasher relay. You can replace the headlight relay with any 5 pin relay (mini) from the local car parts store. 30A is usually the minimum you can get for these but anything over 10A will do the job. As @rweb says, take the old one with you and get a sealed one if you can.

 

The one on my bike (2008 America EFI) is an Omron, part number G8HN-1C4T-RH automotive relay, I guess its the same one on other bikes. Triumph part number is T2506035, called 'changeover relay', confusingly also known as 'headlight relay' and 'starter relay', but it's the same thing. Various UK Triumph parts suppliers have them at around £10 - £11 each, that's around $14 - $15 US - but as already suggested, go to an auto parts supplier, and you'll get the exact same one for maybe half the price ..... but are you sure that your old one is buggered ? - these things are normally bomb-proof, unless its obviously damaged or corroded. The pins should be numbered, if you put an ohm-meter across pins 1 & 2, you should get around 124 ohms - if so, put 12v across pins 1 & 2 and you should feel or hear a click as the relay is activated (you don't need a big battery to do this test - the relay only needs 1/10 of an amp to work) - if those tests check out then put the meter across pins 3 & 4, which should be connected (zero or one or two ohms at most) if the relay is not activated - when the relay is activated, then pin 3 should connect to pin 5. Worth a try, it may save you $5 or so, which is a couple of beers ......

 

I'm a total newbie on my bikes starting system. I'm getting a click and the bike won't start. I've changed the battery. Now I'm looking at the relays. I've found a relay next to the solenoid. But I believe there are 2 more relays somewhere. Not sure where.

I figured the one near the solenoid was the headlight relay.

 

Could be due to a number reasons - locate the starter solenoid, which is the biggish lump of plastic with 2 very thick wires bolted to its terminals, and a single thinner wire (or maybe two) on a push-on terminal, and put your finger on it to see if you can feel a click when you push the start button - if you can feel a click, check that there is 12v on one of the terminals, which should be there all the time, ignition on or off, as it comes directly from the battery + ..... when it clicks, i.e. when the start button is pressed, there should also be 12v on the other terminal - if all this checks out, then suspect the connection to the starter motor (one of the two thick wires, the other one should go straight to the battery +) or it could be the starter motor itself ..... If you can feel no click in the starter solenoid, then put a voltmeter on the thinner, usually white/red wire that goes onto a small terminal on the starter solenoid and see if 12v appears on it when you press the starter button - if it does, suspect the solenoid itself, or its ground connection - if you don't get 12v on the white/red wire, then the problem is likely in or around the headlight relay, because the white/red wire is fed from the headlight relay, which sends 12v down it to the starter solenoid - the fact that you do hear a click means that the headlight relay is operating, but there may be a loose or dirty connection on the relay end of the white/red wire - is the headlight working ? - if so, then 12v is reaching the headlight relay, it's just not switching the 12v to the starter solenoid, either due to a bad connection as mentioned above, or rarely, a fault in the relay's internal contacts. There's one other possible cause I can think of, which is the infamous 'click of death', a feature of early EFI models caused by the ECU aborting the start procedure because it thinks there's not enough volts, but the fact that you changed the battery puts this possible cause out of the picture, assuming the battery you put in was fully charged ? .......
I hope you find the above not as confusing as it was to me trying to write it ......

 

Pretty clear actually. The headlight relay is located where exactly?

 

On my bike, a 2008 America EFI, its a pain, because its mounted under the tank, on the frame spine, just above the engine, and I have to lift the tank to get at it - same on the Speedmaster. On other models its located in or near a side panel, nearer the solenoid I think - much easier to get at. The relay itself is just a blue plastic cube (maybe a different colour on your bike) easy to pull out of its socket, with 5 pins. The relay is an Omron G8HN-1C4T-RH but as I say that's the one on my bike - earlier or later models may have used parts sourced from different manufacturers, but I think the actual relay itself conforms to an an auto industry standard configuration as far as pin layout and size goes - so different makes are interchangeable. BTW, I'm working on a simplified and easy to understand diagram of the starting system electrics, which I'll post soon. Electrics are pretty easy for me because I've been in the industry for many years, but not all of us have - having said that, even I sometimes have difficulty tracing an automotive circuit, they can be a bit confusing ...... watch this space ....

This may help ......

 

Thanks perfect

 

So I found the starter/headlight relay. I can see that the click is emanating from there.

Following Forchettos post I opened it up and gave it a good clean with contact cleaner.

However it still won't start and the headlight doesn't dim when I press the starter leading me to believe the relay is faulty.

Can I purchase a new one from the autoparts store or do I have to go online and get it from a triumph dealer?

Quite a few people, including myself have already mentioned several times that these relays are available from an autoparts store. If you get it from an online Triumph dealer you will pay twice the price or more and have to wait. Your choice, but its just a normal relay. Try to get a sealed one, because the stock one is prone to water ingress from spray off the rear wheel or bike washing.

 

I'll get a relay tomorrow.

Put a jumper wire on the solenoid . Lots of sparks. Turned over once but didn't start. Wonder what that means.

 

Lots of sparks are normal, a lot of current goes through the solenoid - if it turned over once (then stopped), is the battery fully charged & OK ? - check battery connections, solenoid connections and connection on starter motor .....

 

I short wired the relay and now it starts perfectly. Just ordered another relay.

Wanted to thank everybody. My local motorcycle shop was busy months ahead and would have probably have fleeced me when they finally fixed it.
