SV1000 failiing to start

[neilhatch]

After riding up to Angel Islington last night to get a tail tidy off Myisis (great bloke, great tail tidy) my SV wouldn't restart for the home journey.


I thought it was over heating (105C when I turned her off) so left to cool.

Once fully cooled I tried to start, dash would light up all very normal but when trying to fire up the dash would fade and then die (clock also reset), then it would not come back on straight away. Tried bump starting (thanks to all the people that either stood laughing or drove past honking in the 80+C temps). Bumping didn't start, probably not enough compression rather than anything else.

Eventually decicded it must be elecritcal, starter motor wasn't even trying to turn. took the seat off (thanks Suzuki for a full tool kit) and swapped out the ignition fuse for the spair, didn't fire. Re-connected all the connections I could with a lot of cursing, wiggled a few more fuses, all I was getting was a shorted conenction sort of sound from one of the large fuse boxes that sits behind the battery. Eventually after lots of BLUE, a lot of sweat and LOTS of wire wigelling it fired up straight off. Got home safefully and thought all was good, but this morning it all happened again. Same miss connection noice from the fuse box and dieing dashboard. I've left it at home on the battery charge.

Any ideas what this could be? I'm doubting it is the battery because the dash wouldn't have lit and it shouldn't have started if it was.

Need my bike for work so is a bit of a pain.

Any ideas appreciated.
Cheers,
Neil

Hmmm. Check for wired shorting out. When you wiggled things about you might have broken the short but it may have come back when you wer riding... Other than that I cant help! :(

Yea, I'd go for chaffing wires, or a bad connection somewhere. There are lots of connectors...maybe you can have a look at all the connectors you can get too and take them apart and clean them.

WD 40 is your friend, disconnect all the connectors quick spray of WD 40 and plug abck together.

Rear HT lead? or rear coil? I just had a similar issue, could hear shorting around the fuse box area under seat..found the ht lead had corroded(it fell off in my other halfs hands) and after swapping out the rear coil...hey presto she stopped the tomfoolery, and so far the gremlins are banished

Could be worth looking at? dunno if you have coils...so cometh here experts to put me right!

I'm not sure that the bike is turning over, so the issue should be somewhere in the starter wiring, if it's a problem engaging the starter relay.

The fact the dash lights up doesn't indicate that there's enough juice in the battery to turn the bike over. I would say check the battery is fully charged, check the charging circuit and start testing for a poor wiring connection.

Best of luck.

The fact that it did eventually start must mean the battery is ok.

Was it turning over but not firing?

Thanks for all the feed back people...got a few things to check tonight.

I'm guessing the battery is fine but I have left it on charge for today. The starter wasn't kicking in. It was just electircal noises from the fuse area, not sure what circuits they are on (will dig out the manual tonight)....the sound when I ping the start button can only be described as sounding like a dolphin. :nemo: :confused::confused:

Sounds like the relay maybe shorting there then... :(

Well excluding the possibility of a trapped dolphin, once you're certain the battery is charged, put it in and try to start the bike. Hopefully it won't work as an intermittent fault's harder to identify. I would trace the positive lead from the battery terminal to the starter motor relay. Pull the plug out of that (I believe it's a 4 way plug) and check the connectors are all ok, sometimes they snap. Also check that both battery terminals and the terminals on the starter relay are all on tight (being careful not to short the connectors to the frame if the battery's in). Also check the connection to the starter is tight.

After that it's down to looking for chafed wires and dodgy contacts.

+1. Also trace the thick orange wire from the fusebox to the dash area, and also from the fuse box to the ignition switch.

If it doesn't start, remove fuse 4 & get a multi-meter on the connections. Chances are that'll be dead. If so, follow the Orange/Grey to the indicator relay & check there for continuity.

Also, check the red wires from the fuse box, as these come from the master fuse.

Simply check as well is battery terminals, but that should be sorted if you remove the battery to charge it.

Also have a look and the ground connections from the battery.
