Silverwing wont start

Now something broke on my Honda Fjs600 2008.

Its really good and shiny condition, only 20000km/12000 mails on the clock.

Normally in the dash, lights like V, FI, P, ABS, come on and then they go off.

Normally, after turning the kill switch to the position, I hear the sound of the pump.

Now FI light does not come on at all to the dash.

I dont hear the sound of the pump at all.

The fuses did not burn

the main fuse did not burn.

When i try to start, the headlights dim, as if it would take the power to the starter.

Nothing happens, no relay sound, no nothing. I suspect its not drawing power to the starter at all.

The problem started when I tried to start with a empty battery.

Now, the battery is new and there is power for sure. All the other things working normally.

I do not think its Kill switch because the Fl light does not show at any point.

If the fault is in KillSwitch then FI light should show when turning the key on. It doesnt

If there was a problem with the sidekick detector, then the light should also come on to the dash at first at the on position.

Out of the forum, the reason is probably the fuel relay or ecm.

I suspect the problem is ecm when it does not even blink light FI light.

If the ECM detects a failure in the FI system it would start blinking, giving a fault code.

Any ideas of the problem or how check and find the problem?

Best Regards,

Jacky

Are you forgetting the sidestand?

Hi Jacky, I assume you are doing your test on the Main Stand.

Use a pair of Jumper cables to an automobile with a known good battery, I understand you have bought a new battery, You do not state that you have charged it or not. If your bike still refuses to start after using the Jumper Cables,

Then I believe your problem is in the Right Handlebar Switch assembly, Assuming that you have the kill Switch in the down-run position, The side stand up.

Remove the two bottom Phillips screws from the Switch assembly, Carefully noting the position of all the wiring so that you can get to the start switch in the bottom of the assembly. If this plastic switch is melted, You will need to replace the switch assembly.

Your bike has lost its memory because the power supply has been interrupted, The memory will recover with use and the Quirks will disappear with use.

This Right hand Handlebar switch assembly has been a problem for 15 years. Honda has not corrected this delicate plastic switch tendency to fail. When the contacts get dirty and with a weak battery the ark that takes place melts the switch. I have replaced dozens of these over the years.

I hope this corrects your problem. See my starting procedure to prevent damage to your new switch.

Looks like a Relay issue

Hi I`m going to have to buy the switch soon, but as its intermittent I`ve adopted Lloyds start Technique for now.

Its helping but still a bugger.

I see you can buy a non Honda one but it has no throttle end/twist housing etc.

Thanks again Lloyd.

Best SWD.

PS can you buy just the switch assembly on its own ? anyone know.

Bit dissapointed with the SW as 9 years of a suzuki and 6 1/2 of a Yamaha and never an issue of any kind starting. Maybe just lucky.

Jackyjaxx, Please let us know how you get on with this problem.

We all benefit from shared knowledge.

The switch assembly is available complete from Honda, The Throttle cables have an adjustment inside the rubber protectors located at the right handle bar, Loosening these to gain as much slack as possible will allow you to disconnect the Throttle cables from the switch assembly. Slide the throttle off the bar and proceed with the job.

Unplug the switch inside the front cover, Access is thru the right hand pocket, Remove it carefully and note the spring positioning. Good luck, This is an aggravating repair, Take your time and do not break anything.

Hi Thanks.

I might have a little sneaky look in at the switch at the weekend.

Buy definately on the way out.

Decided to pop a new battery on as well as I think its 10 years old.

Hello,

I have asked many many people & forums, prime suspect is now fuel relay/main relay.

Repairmen say that the ECM/ECU doesnt fail easily.

i dont think its switch assembly in this case, sources say i should hear the pump sound still. Switch assembly problem makes it impossible to start after you hear the fuel pump.

If i have understood right , here is what Honda manual says about the problem (different model/same system)

   PGM-FI SELF-DIAGNOSIS MALFUNCTION INDICATOR LAMP

    When No blinks

   - Open circuit at the power input and
   ground wires of the ECM

   - Blown sub-fuse D (7.5 A)

   - Faulty main relay

   - Open circuit in the main relay related cir-
   cuits

   - Faulty engine stop switch

   - Open circuit in the engine stop switch
   related circuits

   - Faulty ECM

   - Blown main fuse (30 A)
   

Where is the sub fuse located (7.5a)? Is there a subfuse on Silverwing? This diagnostics is for different Honda model. Havent had time to work on it, next thing to check is the sub fuse.

Hi Jacky.
Silver Wing ignition sub fuse is 15 Amp, as to location I would guess it is in the fuse box nearest the luggage compartment, under the seat on the left hand side, if not then try taking the rear left body panel off as all relays are behind it & possibly any 'inline' fuses.

Wiring to sub fuse will be Red & Black from ignition switch one side & Black from engine stop relay & bank angle sensor on the other side

Diagnostics for Silver Wing .. PGM-FI .. No blinks

Open circuit at the power input wire of the ECM

Faulty bank angle sensor

Open circuit in bank angle sensor related wires

Faulty engine stop relay

Open circuit in engine stop relay related wires

Faulty engine stop switch

Open circuit inengine stop switch related wires

Faulty ignition switch

Faulty ECM

Blown PGM-FI fuse (20 A)

Open circuit in engine stop switch ground

Blown sub-fuse (10 A) (Starter/Ignition)

Hi Fellows,
I have the same problem, when i push start lights just dimming.
I took apart the right side switch assembly and cleaned it (I didn't see any burn marks. ) but it just the same- not fixed. Ordered new switch assembly from Amazon ($36cdn).

Can someone tell me where is the
conection for that long cable?

Thanks,
Joe

PS. I can start it with a screwdriver. Removing the two Philip's screws on the bottom and the top part with the kill switch., and conect the two tinny wires on the left side and push start.

From memory, those handlebar looms connect somewhere under the plastic handlebar covers. I can't remember if you need to lift the handlebars up off the mount as well.

Thanks Loosemarbles. I have removed the plastic handlebar covers but still can't see the end of that cable:)

Now I did scrood up somthing cuse the FI lamp not coming on.?

In that case it probably connects under the front cowling. This means removing all the front tupperware. There is a main connection point under there. Getting the front cowling off is a bit of a PITA but with care and patience it's not too difficult, more time consuming really. Maybe somebody else could confirm this.

As for the FI light?...I'm hoping somebody here with more electrical knowledge could help with that.

Sorry can't be more help. BTW, do you have the service manual?

Thanks. No I dont have

Hi lajose.
here's a link to all the manuals you need.
