'00 900 died on start - thougts?

There are two. The problem child is the 5 prong 'main' the other is 3 prongs for the turn signals.

So they're not 'similar'.

I guess that year didn't use a 5 prong injection relay.

Let me do a quick search...brb

Thanks DP

Yeah they are both relays with odd numbers of prongs... In a similar configuration.... But I don't see your point 


Yep that's the little buzzing bastard!  I'll have to see what happens if I jump it per howies directions.

I've got power to that relay   so now it just needs to go some place.

I'm going to be a bit irked if the brand new relay I bought was a dud.

There is a possibility the relay has a bad coil, but I don't think you eliminated a bad battery yet.  The only way to know your battery is good is with a load or conductance test.  Battery voltage is only showing you state of charge.  12. 2 is also not fully charged, though it is pretty close, 75% if conventional, less if AGM.

Short of that is to either bypass the relay or jump start with a known good battery.  You could also bench test the relay.  Hook a known good battery across 85 and 86 on the relay.  The relay shoud not buzz and you should have continuity at 30 and 87 with an ohm meter. Also make sure terminal 86 is a good ground.  One easy method is take a simple incandescent 12 volt test light.  Hook the clip to battery positive.  Touch the probe to terminal 86 in the connector.  You should get a bright light, as if you put it across the battery.

Thanks Howie - I'll brake out the jumper leads and do some bench testing.

Well, the winner is a bad battery. A donor battery brought all the electrics back to life.

I'm a bit miffed the that the battery has died as it's not all that old, a bit more than two years.

My last battery lasted less than a year!  Luckily, as it became completely dry (and very hot) the bike was still able to start and drive, at least long enough for me to detour to the nearest city for a new one.  I, too, ride a 2000 900.

I think my battery's untimely death was at least partly the result of keeping it on a Battery Tender too much.  I'd connect it and leave it connected until my next ride, which over the winter was often two or three weeks.  At some point I noticed that the water level was low, but then forgot to add more water to it before heading off on a road trip.

The battery in this case was a 'maintenance free' sealed one. So no checking the acid levels on that one.
