Non starter ignition lights only come on when battery charger is on. starts when jump leads are connected. as soon as you disconnet leads dies straight away and no ignition lights. battery fully charged.

silly I know but check that the earth strap from battery to engine has not corroded, you can take a jump lead from battery negative & connect it to metal not alloy on the engine to check this, turn key see if it turns over.

The most common cause of a non-starting car is the battery. It is either weak, (low voltage) dead, (zero voltage) or has bad connections. (corroded or loose) I will assume you have a fully charged battery with good connections. (both to battery and starter relay)
If you remove the starter switch lead (small wire) from the starter relay and apply +12v from the battery to its respective prong or lead on the relay, and your starter cranks, your starter switch is faulty. (not to be confused with your key switch). If you jump the two large wires together on the relay and it cranks, then the relay is faulty. If you jump the two large wires together and nothing happens, then starter is faulty, or wires to starter are loose or broken. Picture of starter switch prong on the relay is pictured. NOTE: sparks are to be expected, so don't be too scared.

try tightening battery terminal or remove and clean, check for loose connection, refit connector and tighten properly.

I would check your ground from the battery to the frame/engine and also the positive battery lead where it connects to the starter/relay

Need more info like when you say it won't start, Does it spin over? Is the engine turning over? If not, and a jump start does work, Then it is the Battery or the post connections. That's it! If it does not turn over with a jump then it will be the starter or ignition switch. If u can get to the starter, it can be forced on with a small jumper from the large post to the small stud (usually red)

Hi, the main fuse is on the starter solenoid I believe. If this is OK I would look to the battery. I have had my SV get me to work and after work tries to start then nothing shot battery every time. Try removing the battery please undo negative lead first. Connect battery to a dedicated bike charger (output 1 amp max) see if it will charge. A dead or faulty battery will normally show full charge very quickly do not be fooled by this the battery is lying. When you fit a battery please connect positive lead first. Please never use car or boost chargers and never jump start your bike from another vehicle.

Hope this helps.

Check your battery terminals and make sure they are clean by removing and lightly sanding with some rough sand paper (wipe down when finished), also the wires/cables going to them, they should not move when tightened on terminals. Also clean and tighten the negative (earth) cable/wire and if you have easy access check to see if the main starter motor lead is tight, be careful if you need to tighten it as you can short out the positive (starter motor lead) with the negative (anywhere on car thats metal 95% of it). You have poor connection somewhere which is causing your problem.

There is either a cable not getting a very good connection, solenoid has problems, or there is a wiring leading to a relay that has a bad connections. How is your ignition? Is it loose or have loose wires?

also check the magnetic switch mounted on the starter housing, is supplied by current from the starting switch circuit of the ignition switch. This magnetic action of the switch mechanically engages the starter clutch assembly and electrically closes the heavy switch which connects it to the battery. The starting switch circuit consists of the starting switch contained within the ignition switch, a transmission neutral safety switch or clutch pedal switch, and the wiring necessary to connect these in series with the starter solenoid or relay.

Hi, Your problem lies with the starter solenoid, although you maybe using a fully charged battery to jump it, it appears to be sticking or possibly faulty due to trying to start with poor battery.
The starter solenoid is usually located on or near the Battery compartment, it is cylindrical and has two heavy wires attached to it 1 goes to the starter motor the other to the battery. If you are carefull you can by pass the solenoid by touching the heavy wire going to the starter motor with the jumper lead. Make sure the jump battery is connected and both the NEGATIVE leads are well secure. Put the NEGATIVE lead from jump cable direct to a engine mount bolt or engine itself Not the battery.
There you are FixYa'd
