Posted: 12:53 - 09 Aug 2018 Post subject: Triumph electrical gremlins - possible ECM relay issue? |
|
|
So. A week ago I got back from a 10 day holiday touring through Wales, the midlands, the peak district etc. Went over the Cat and Fiddle pass etc. Was great. Bike ran like an absolute dream. Since getting back from Holiday I did not ride the bike for about a week.
We come to Yesterday. I rode it about 15 miles over to my Parents house, and it worked fine. I rode it about 4 miles over to where my martial arts class is, it worked fine. When I got out of the class? Hmm. I put the key in the ignition, and there is no response. No lights, no whir of the fuel pump, no dash activity. Weirdly though, the indicators and horn work, and I discovered this morning that the brake light also works. I stuck a meter across the battery, 15.5v. After wheeling the bike under a street light last night, I checked the fuses (which seemed OK) and I reseated all the relays too. So in the end I locked the bike up and cadged a lift home from my GF who was pretty grumpy to have to drive a 20 mile ish round trip. I returned today to collect the bike using my beautiful Passat estate and trailer combo.
So The status right now is as follows:
Bike still strapped to the trailer waiting for the rain to stop (trailer ramp is perfectly smooth, so I can't imagine what fun it'll be unloading in the rain ).
The bike is mechanically fine
Turning on the ignition appears to give no response, but it allows the indicators, horn and brake light to work properly so it must be doing something.
No headlights, taillight, side lights, dash illumination, no dash activity of any sort.
I don't use the kill switch a lot but I confirmed it's in the 'run' position. I checked it in both positions just to be sure I wasn't being a dumbass.
Battery showing 15.5v (healthy I'd say).
A late night street lamp check of the fuses did not show any problems - This includes the ignition fuse, ECM fuse etc.
So the only common factor I can see amongst this is the ECM relay which doesn't have connections to the horn, indicators or brake light circuits, but does control the ECM (obviously) which has many links to the dash, fuel pump etc but interestingly this relay is also wired directly into the headlights... Seems logical, right?
Hopefully someone with experience of Street Triples or Daytonas will confirm, or some other person generally cleverer than me will just tell me I'm talking nonsense... ____________________ British beauty: Triumph Street Triple R; Loony stroker: KR1S; Track fun: GSXR750 L1; Commuter Missile: GSX-S1000F

Might be worth checking the battery in your multimeter ____________________ Current Bike: Honda CG125 ES4 // Honda CB600FS Hornet // Triumph Street Triple R |

It is an ancient meter... Maybe it needs a new battery? I'll go look now.
[edit] Replaced meter battery, now shows 16 volts! So I checked all of the other 4 bikes in the garage (as below, plus the GF's ER6N) and they all show an identical 16 volts. Methinks I'll be buying a new multimeter in short order!
I'm still thinking ECM relay... [edit] ____________________ British beauty: Triumph Street Triple R; Loony stroker: KR1S; Track fun: GSXR750 L1; Commuter Missile: GSX-S1000F

For those that are interested, I took the tank and airbox off, and found the burned pin exactly as I expected:

and for those who are interested, here's the wiring diagram:

The brown wire goes from pin 1 on that connector and appears to connect to the starter solenoid. ____________________ British beauty: Triumph Street Triple R; Loony stroker: KR1S; Track fun: GSXR750 L1; Commuter Missile: GSX-S1000F

Haven't had time to put the airbox and tank back on yet, but will hopefully do so today. ____________________ British beauty: Triumph Street Triple R; Loony stroker: KR1S; Track fun: GSXR750 L1; Commuter Missile: GSX-S1000F
