Default Electrical issues and the aul' sv650

Right lads, i know that problems in the electrics are unheard of in matters of sv650's but here's mine right now: finished work, started the engine with a bit of choke for good measure and allowed her to warm up for about 2 mins. Put my sexy leg over, sat my arse comfortably and got ready to go. As I switched on the lights i noticed the revv counter dancing a bit. Previous experience told me there's an issue with the supply of electricity but i figured it'll be grand since the engine was already running. Gave her a rev or two and as i was getting ready to shift into 1st and go she went dark.

Checked the battery, bolts, leads. Put the battery on charger. Checked the fuse box. Nothing happens. Well, something worth noting- the heated grips still get juice from the battery and get warm. But other than that not even a flinch when i turn the ignition on. I did what i knew, now i turn to the wise men's council. Halp!

I'm far from an expert but is the battery getting charged by the rectifier/alternator ? If you have a multimeter, I would check out the charging just to tick some extra boxes when troubleshooting.

Yep, battery's grand. Might be a blown fuse in the main relay but i've no tools with me and the whole thing is really cramped there

Had an almost identical issue with the starter relay recently...

It would run for a while then vibrate itself to death...

Nearly fell apart when I took it out...

Your heated grips must be wired directly to the battery...

Thanks Bruce. Grips are indeed fed directly from the battery, I only mentioned it to remove all doubt that the battery wouldn't be ok. Anyway, called for breakdown recovery and my bike is now in storage as they wouldn't take it either home or to a shop today, being late and all. Did you find it easy to access the relay on your sv? When I took the side panel off i could see the thing but I was barely able to touch it with the tip of my fingers, really frustrating. Granted, I was tired and angry by then but still, it felt like i will only get to it if i remove the plastics and subframe.

Mine is a stripped down track bike so no access issues...
Would have thought it would be easy enough to get to once the fairing panel is off...
There's only a piece of rubber holding it in place, once the wires are off it should pull right out...

What am I doing wrong, ffs? So I found the main fuse blown, the 30A one. Replaced it. Put everything back together. Turn the key- nothing, not a light in the dash, nothing. Re-checked the battery, fuses and main fuse. Used a multimeter, steady 13.1- 13.2. Yet she is dead. I would have thought that once the main fuse was replaced i should see some difference. Please, give me a thought, an opinion, anything.

Try turn the ignition on slowly, contacts may be fucked in it

Starter relay that the main fuse is located in is most likely fooked...

Could I have fried it? Maybe I reconnected the leads with the wrong polarity. I'd love to have done something stupid myself and know it than deal with a frustrating mystery, particularly when it comes to the electrics

Once the magic smoke wasn't released, it should be fine

Take out the relay and look at the contacts where the main fuse sits...

Was a lot of corrosion in mine...

With the rain being a royal pain in my royal cheeks, I left it for a while. Had a go at it today. Main fuse i had put in was visibly blown. So I put a new one in and as I was replacing the - back on the battery I heard this new fuse also going "pop".

I understand this would be a sign of a short somewhere, and my knowledge of fault finding in electrics is ..less than ideal. Would probably find a mechanic willing to take it into shop on tuesday as all are taking monday off afaik.

So, any wizard feeling bored and willing to help so I can get back on her before i forget how to put my leg over? I've got 50 quid and a bottle of whiskey, but I'm open to more discussion on this.

Pull all the fuses out and fit a new main fuse, start replacing the fuses one by one until the main fuse blows, then you know which circuit has a short.

I would suggest a careful examination of the wiring loom from the main fuse along the frame - it will be painfully apparent in the cold light of day where there is some chafing and an exposed wire shorting out on the frame.
