This one should do:

I really would not be wanting to buy that particular example. While I have a number of well made mechanical items from Chinese manufacturers on my bike, electrical components bought cheaply on ebay are a different matter.

Try this from Wemoto. It's more expensive but it's from a reputable supplier.

If battery is failing it can make starter solenoid chatter, it goes like this....

  1. solenoid closes and puts power to starter motor.
  2. starter motor draws power and system voltage drops
  3. the drop in voltage causes solenoid to drop out
  4. solenoid drops out and takes power off the starter
  5. the system voltage rises
  6. the rise in voltage allows the solenoid to pull in again...
starts again at 1. and continues until you take your thumb off starter button LOL

Before spending any money Id check all the connections on top of the obvious ones you have already done. These include the battery terminals and the frame and engine earths as well as the block connecters. Then buy a new solenoid

As above, the OP should check the battery is holding charge first.


For OP:
Just set the multimeter to a fairly low DC volts scale (there is normally one around 20V). With the ignition off test the voltage across the battery terminals, it should be 12.6v. If it is less than that the battery is not holding charge (and that will probably be causing the problem).

I have no view on what the OP should spend his money on. One is a £10 part, the other is £30... I know which one I would fit

As I said, I have a number of well made Chinese mechanical components on my very well used SV. I have in the past made the mistake of thinking that the same quality extends to imported/ebay electrical bits. I invariably end up spending a second time to replace the poor quality and occasionally downright dangerous electrical bits from sellers such as the one to which you linked.

How you doing mate?
Found that my clutch lever has worn enough so that the switch only engages when the lever is angled upwards slightly... just changes my starting procedure subtley! But changing the switch did nothing, obviously.

Well, fancy that, how did you diagnose the problem I wonder? Well done.
I got rid of the clutch switch, I soldered the two wires together so it is bypassed, I’m much happier having less things to go wrong than more.
