Hi
I recently purchased a 1989 sl 400, the last owner keeped in extremely good condition it's only dun 55000 Km (I'm a kiwi so everything is in Merrick) And as far as I know there have been no mode dun to this bike bond a windscreen.
I went to go for a ride today, but what I went to start it the engine didn't kick over and the starter motor won't shut off with the kill switch or by the off position with the key. So I've removed to power cord the the starter but whenever I attach it. it's still running current and the starter begins to crank agent even when everything is in the off position.  :'(
Has this happened to anyone else/what do you all think is causing this?
I think it's shorting somewhere but I don't know where to start looking?

Thanks I think it is a stuck solenoid
I hit it and its unstuck but ill defiantly need to replace it
did you get yours from an online store? if so can you like it please

I'm pretty sure it's sepreit and is sitting under the seat
It's starting properly now I'm going to look for the part
If anyone has a part number it will be much appreciated as I don't have an owners manual yet

Do a search on Amazon, EBay or other site to get a better price.

yeah but if it sticks and i'm in the middle of town opening it up to hit it is going to be a major pain in the ass
Thanks for posting the part number, I'll let you all know there I get the best price from

Thanks, I've got one through a locale bike shop for $30 nzd
I would get it on line but shipping and estrange rates the price jumps up a lot, and I'll have it by tomorrow at the latest.

US $8.49
Shipping to NZ US $59.99

Dangit' Kenny... and that one's even cheaper!...

Really,.. relays are relays...  as long as they handle the amperage, any will work.
If you ever look inside a relay, it's just a set of contact points, like an old school distributor... a small electrical charge closes the points, and that allows the higher amperage to pass.  (saves running a battery cable to the handlebar and back)... ...
