Hey guys,
So a couple of weeks ago, I was riding the it blew the main 30a fuse.
When I got it home, I noticed one of the rectifier plugs was burnt, I unplugged the rectifier and the bike idled fine without blowing the fuse, so I ordered and installed a new Mosfet Rectifier, with the recommended wiring change, which was the power (with quality cable and connections) to battery via a fused link, I earthed it to the frame, I also installed an extra earth from battery negative to frame.
I got it running and fired up, idled for about 10 minutes and gave it a few revs etc to see if it would keep running.
Everything seemed fine to I geared up and jumped on to test ride, I have a bit of a steep driveway, and as soon as I backed down the drive it cut out again, main 30a fuse blown again…
I can change that fuse, start it up and it’s fine, soon as I back down the driveway, it blows it again, it’s got me gobsmacked what could be causing it!
Any help is much appreciated 🙂 -
Take a look at this topic , it has a lot of info that might help, (I hope!)

thanks heaps for the reply, I’ve actually had that thread open all week though I haven’t followed every step thus far, It’s just so weird everything seems perfect until I back down the drive, I could put a new fuse in, start it right now and run it for 15 minutes without any dramas, but soon as I back down to try ride it, I’m sure it will die… but I’ll give it a proper look on the weekend

Just an update, I reinstalled the battery, installed an extra earth and tidied up some more wiring, it will now run and keep running (even when I back down the drive) I took it for a quick ride and it quickly started breaking down/backfiring and I got an F1 code and went into limp mode, I got it home, for some reason it won’t show me a ‘C’ code, which I thought the Delphi ecu’s did? but when I turn the ignition off and on 3 times, I get the flashing 10-3-5 sequence

The closest i can get is 10-3-5-1 (Failing ignition coils) Nothing i can see here for 10-3-5 (0r 10-3-5-0)
You are absolutely correct âşď¸Ź I checked again and there is a final 1 at the end of the sequence, I also have a cracked gear position sensor though the inside looks fine and I’ve had no issues with gear selection or neutral switch etc, hopefully I can pick up some coils before the weekend, does anybody know exactly what model Suzuki’s suit? I live in Australia so will have to try find some locally

Also do you have the list of codes? I have an efi user manual but it only lists the ‘c’ codes, I couldn’t find any info on the flashing fi codes

It’s in the forum service manuals uploaded here:

I do have a copy of that and referred to me it, but I could only find the ‘C’ codes and when I tried to bring them up on my bike I got ‘no Er’ on my clock face, I saw something about cycling the key 3 times and counting the fi flashes and got the numbers above, but couldn’t see where to reference them in the manual, I am new to bikes, the Hyosung has been my first, I do have a v-strom now which is handy as I can pinch the coils from that to test the gv650.

The Delphi 650 (GV or GT) would get mostly the same codes but i’ve yet to find something “GV Delphi” specific yet considering both GT and GV don’t share the same ECU’s or dashboards, the flashing sequence of the red Fi light you said seems to match what i found in the books if its true.  You would have to read the flashing sequences again , if it happens again but unplug the battery for a day (just to see if the same flashing errors occur)  – The LCD panel is funny sometimes, it can say FI, 0, Fi, 0, while riding not telling me much, but if i park up and flick the kill switch 3 times rapid before starting, the red light will flash telling me the true issues. The red Fi light is more handy than the LCD panel.

I’ve confirmed the front coil is cactus, I’ve noticed for the older models you can use sv650 coils, is there a conversion or higher quality replacement that we can use for the later style coils on these bikes? I’ve seen the ones in the store here, but It’s already been a month since I’ve ridden it and I’m hoping I can find something locally so I can get it going this week! It will take a while for them to get to Aus from the UK.

What part numbers are printed on the coil or any picture you can post of the current coil ?
SV & Hyosung in earlier days used the same coil made by Mitsubishi Japan (the long oblong ones) so no difference  , however the later smaller coils are made by Hankuk Korea , and Delphi Coils are Delphi only.
So if you have a Delphi coil that looks like a shotgun , then you can only use Delphi coils as not to trip up the ECU, Delphi ECU also expects the coils to have certain resistance secondary and primary , hence the forced change over to stop older coils fitting to delphi units. Their best upgrade for the coils is good HT leads & Caps (NGK)

yeah it’s the later Delphi one, has 28198992 followed by 3A04A on a sticker on it, I’ve ordered some new ones and will fit some quality leads and caps to it, I go away for a week on the 22nd so will be a while before I can ride it again unfortunately
