I've been a fool...
Long story short (for the long story -and how to avoid this mistake I made-) see below
I wrecked my starter relay by trying to start the bike for too long when the starter sprag clutch didn't work properly.
My question is about the starter relay:
I found three different part nr's and I found a webshop
which has all three in stock. But there's a big difference in price between those three. So I wonder if they are all the same and will fit my 900SS...
These ones are advertised:
Part nr: 09070 Price: €17,56
Part nr: 39740011A Price: €30,40
Part nr: 048638460 Price: €185,64 (!!)
Anyone got any idea about the difference between these starter relays or an idea about this huge price difference?
Long story (and how to avoid making the same mistake as me)
My '97 900SS wouldn't start.
Battery fully charged, starter relay opening and closing just fine, starter motor working.
Problem is that the starter motor (at best) rotates the engine for just 1 compression stroke and then it starts running free. So it doesn't turn the engine over for more then one stroke. Sometimes it even doesn't do one compression stroke and it starts running without turning the engine over.
I should have stopped trying when I noticed that but I tried just too long. So at one point, the starter relay got stuck and I couldn't get the starter motor to stop running (kill switch, key,...). I assume the contacts in the relay are melted together because they heated up when I kept on trying to start the bike.
Luckily the bike was on it's paddock stand with the seat removed and the tank up so I could quickly disconnect the battery before the starter motor drained and killed the battery.
Some good advice: if you're bike wouldn't start because the starter motor doesn't turn your engine over: stop and fix the problem (which is probably the starter spray clutch). Don't keep trying and hoping that at one point the starter spray clutch will (magically) work again. It could ruin your starter relay. If the spring on the starter spray clutch is broken or stretched: look for an SKF 19778 oil seal. It has the same spring and is way cheaper then a whole new starter sprag clutch. (All credits to this forum and its users to point that SKF-fix out to me! Thanks guys and girls!!)
P.s. My spelling checker changed sprag into spray in the title. Can't edit it...
