Hi All,
Without any warning at all my 07 S4R just died on me while out for a ride yesterday. There was no warning signs and the bike was running faultlessly until then.
There is absolutely no power going to the ignition, turn the key and NOTHING! No dash, no fuel priming, no funny noises, absolutely nothing! The really strange thing is that the speedometer is stuck at 30km/h! I checked all the fuses in the fuse box - they all still in tact, checked the battery connections - all tight, checked all wires and connections I could for any loose ones or dodgy looking ones and all seems fine...!?!!? ???
Has anyone had a similar problem? Any input into diagnoses would be appreciated.
Many thanks
Chris
Did you check the large 30 amp main fuse near the battery?
Hmm no I didn't know of such a fuse... I didn't see anything glaringly obvious when I was poking about... so which side of the battery? Near the side where the leads come off it?
If that fuse is blown do you know what might have caused that? Is there a potentially bigger underlying problem? Or just a simple fuse malfunction?
I have unfortunately flown out of the state today so will have to check that when I get home on the weekend:)
That fuse protects the charging system, and is in the positive battery lead. It should have a plastic cover which is why you didn't notice it.
It could be a defective fuse, or it may be a sign of a problem with the R/R, the alternator, or harness. Electrical problems are difficult to diagnose in person never mind over the internet. ;D
See if it's bad and if it blows repeatedly and we'll go from there.

+1 to what Ducpainter said. After checking the fuse, the R/R might be your next stop. Similar thing happened to me and it was because my R/R was kaputz.
Cheers mate, I appreciate your help! [thumbsup]. Whats an R/R? Is that the Volage Regulator? Apologies for the dumb questions...

R/R = regulator/rectifier. Serves the same purpose as a regulator but has the AC to DC rectifier built in.
Cars typically have the rectifier in the alternator.

Okay, so i checked the main 30 amp fuse and sure enough it was blown. When I put a new fuse in it sparked and blew before i could even get it in properly!! [bang]
What would be causing that and what is the next step in the self diagnosis (I understand its practically impossible to diagnose an electrical problem over the net but if I could eliminate a few things before taking it to the shop (which is 200km away!) it would save them having to do the same thing at $120 an hour)
Thanks once again
You have a short. First, disconnect the regulator and try a new fuse to rule the regulator out. Then get out the wiring diagram and start tracing.
Specifically check the wiring to the r/r. If its melted together it'll blow this fuse and no others.
Managed to get a chance to look at the bike again this arvo and made some progress. Unplugged the r/r and put a new fuse in and it didn't blow! [thumbsup]. Had power to ignition and the engine started (only let it run for one second just in case not havin the r/r connected caused issues). Tried to plug the r/r in again and it sparked, so it definitely is the r/r!
Thanks for your all your help everyone!
Next question is what would be the best r/r for an 07 S4R? There seems to be a bit of hype surrounding the shindengen unit. Are they easy to do a DIY install?
Thanks all.
Shindengen is a known high quality unit, but requires modification. Ricks http://ricksmotorsportelectrics.com/part/10-008H/MDZEdWM5MTZNb25zdGVyTVM0Ug== (http://ricksmotorsportelectrics.com/part/10-008H/MDZEdWM5MTZNb25zdGVyTVM0Ug==) is also MOSFET and a direct replacement. Yeah, I know, 1 year off, but it is the same. Is the Rick's Hot Shot as good as the Shindengen? Dunno.
Thanks Howie!
Think I am going to give that Hot Shot unit a go! Do you know if they ship to Australia?
Has anyone else used the Hot Shot unit and if so whats their opinion on it??

Hi Chris - installed the Hot Shot unit from Rick's Motorsports in my 02 S4 and 06 S4R. Both have not let me down and it runs a decent amount cooler than the OEM one. It's a tad smaller and as most have said it's a direct plug in. Will shoot you some pics of it in stalled in my S4R later today if you'd like.
Thanks MonstaS2R! I would really like to see pics of it installed if its not too much of a hassle ;D
If you are thinking of going with a Shindengen unit this guy sells a nice kit.

I plan on putting on of those on my S4Rt eventually.

Thanks for the pic mate. It does look good!
Hi All,
Got the Hot Shot unit from Rick's Motorsports this week, works a treat! Stoked to be back on the road!
Thanks everyone for your input and assistance [beer]
Cheers
Chris
did the kit come with the connectors to plug and play?

Yeah the plugs fit right in nicely, no mods or soldering! Easy ;D The people at Ricks Motorsports were great, they wanted some pics and diagrams of my original unit so as to ensure I was purchasing the right replacement unit and once ordered it arrived within 4 days across the other side of the world! Couldn't be happier! [thumbsup] The part # for my bike ('07 S4R) is 10-008H, http://ricksmotorsportelectrics.com/part/10-008H/MDZEdWM5MTZNb25zdGVyTVM0Ug== (http://ricksmotorsportelectrics.com/part/10-008H/MDZEdWM5MTZNb25zdGVyTVM0Ug==)
Thanks. So it really does run that much cooler? I tinkered with putting it under the bike but the wires on the stock unit aren't long enough. [bang]
