Hi there,
i've just aquired an SV to take into Minitwins and have a problem with it starting. The previous owner had fitted a smaller battery to save some weight (fair enough) and when I went to view the bike/buy it it started no problems under it's own power.
However, when I went to start it some 2 weeks later it was not having it, all that happend was the dashboard went dim and the starter relay just clicked the once, I did notice that the lead down to the starter motor became very hot very quickly.
After a few attempts the starter solanoid the went off machine gun style and the lead remained cold but like I say obviously no current going down it.
Charged the battery and re-fitted, again, no relay noice just hot wires. Then after a few attempts, relay noise.
I went to halfords and got a pukka Yusaba battery 65 quid the correct one for a pointy as per haynes manual. Probably twice the physical size of the one on the bike when I brought it.
I have charged this up for a few hours and although the "OK" light wasn't lit on the optimate, I fitted it in hope. Same problem. The relay is allowing current to the starter motor but the lead just gets incredibly hot. The starter relay isn't clicking and going off.
I stripped the starter motor and cleaned the contacts and the connections are in excellent order. I have tried to bypass the starter relay by placing a jump lead on the battery +tve and on the starter motor connection rod, all this does is make the jump lead literally smoke and glow orange where it is touching the battery +tve and starter motor.
Is it simply the case I wait until the new battery is fully charged to try again or is there something else to check. Done all the usual searches and check clutch switch and s'stand swtich. Starter push button stripped and re-assembled nothing untoward anywhere
