Charged dead battery, installed, blew fuse.

I'm trying to get my head around what just happened.

So my SV wouldn't start, the previous owner said there was something up with the battery, it runs fine after being jumped. The ignition came on fine but once I hit the starter motor it tried to crank before everything stop and the dash lights went off.

Me being me thinking I knew exactly how to solve this decided to take the battery out and attach it to charger.

Now I left it attached to this 6A charger for about 30 minutes when it told me that the battery was fully charged. I thought great, let's fit it back in the bike.

Put the battery back in, turned on the ignition which worked fine but this time I hit the start button... BANG. Then everything died. Now turning the key has no effect.

Now it's obvious that I've blown the main fuse, but I don't understand how?

Being a new bike to me and me maybe slightly lacking in the mechanical side of things.. I'm just going to ask.. How do I fix this and get the bike working again?

I feel like such an idiot and having very little money to play with I'm only able to fix anything on the bike in my own garage, I just can't make sense of what happened in my head.

The simple answer is a short somewhere. The question is where...

Firstly, do you have a supply of main fuses, these might be handy?

Secondly, have you got the battery round the correct way (yes I have seen this before)?

Third, which model SV have you got?

Soon as the shops open this morning I'll head out and get myself some. They're 30a fuses am I right?

Unless my eyesight is failing me for some reason I'm 99.9% sure I connected it up the right way, I will check in just a moment once I get outside, I can understand why you'd ask though!

The bike is an SK5.

Terminals go to the rear, that's the way the battery sits in the tray. Positive on the left,

Battery round the correct way - Check
New fuses - Check
New Battery ready to go - Check

Unless the previous owner changed it for a slightly unusual glass mat battery which has terminals on opposite corners. Then it's not so straight forward and very confusing.

Luckily I had a set of 30A fuses spare.




I'd go looking at cables that may have rubbed on the frame as a starting point.

Aye, mine has got a motobat battery on it, with 4 terminals, so could confuse.

The only thing I can think is that it's somewhere near the terminals as it only happened once I'd taken the battery out and replaced it, before it happily tried to start, so I'll go have a look. Time to figure out how to take off all these rear fairings

So I replaced the fuse, and installed the new battery, woo the bike starts! I thought I'd take it round the village to give it a little test, managed to take the bike down a few streets but every time I was getting to a junction and knocking it into first the engine would cut out, and each time I started it the bike seemed less and less like it wanted to come to life. Hmm is this just due to a lack of charge in the battery?

I've seen something similar on one of my bikes. It was a faulty reg rec.

My first suggestion is to test the charging system. There's lots of tutorials on her to help. Do that first and report back...
