Hi all, happy New Year to all. I now need some help. This morning my 250NB refused to turn over, I checked the battery and found well charged. The solenoid sounds odd when the starter button is pressed, instead of the usual click it a series of clicks! Is it on the way out. I have checked the wiring from the handlebar button to the starter, all ok.
Thanks

Hi , happy new year to you .
A series of clicks is normally not enough power in the battery . If you are happy that your battery is fine it could be a bad earth or the terminals from the battery / solenoid to the starter motor . Also check the terminal on.the starter as this gets a lot of crap off the front wheel.
Have you tried jump leads .

Many thanks Graham, you have confirmed my suspicions. I will get the battery checked under load. At the my local Halfords.

Hi Rooster. I would go along with idea of a faulty battery. My SD seems to have got through 2 batteries in 2 years. I wonder if someone could suggest a good quality battery for the SD. My thoughts are Exide or Yuasa. It's at times like this I am glad my SD has a kickstart, just 1 or 2 kicks and away it goes. Who needs this new fangled electric start?!! All the best. Mike.

I sometimes start my SD400 in third gear on a push start, it's some sight to behold, first I run along side the bike to build up initial momentium, then I throw my leg over it and still keep running, then up with my feet, and arse hard on the saddle, let the clutch out and maybe a little help from the starter and a way she goes. The neighbours around here think I am a bit touched !

I forgot to add, vehicle batteries tend to fail in frosty weather, sometimes if you get through the winter they will recover for the summer. Check the water level is above the plates in each cell. Also I had a Bosch battery in my van for the last 7 years, just replaces it recently with a new Bosch guaranteed for 5 years. Gs, Exide and Oldham fairly good batteries to I think. My father got 20 years out of an Oldham battery years ago.

Just a thought but if the battery is good then I suggest checking the condition of the power cables , especially the earth cable. If it has some internal corrosion it will add extra drain to the system and can prevent the full ampage going to the starter solinoid / starter motor.

Before buying new i would leave the battery on charge overnight just to check, i agree with scania though the frost will kill a good battery

Many thanks for your comments. So far I have had the battery checked-ok. All the cables have been cleaned and checked for continuity. That leaves the Starter and the Soleniod switch.. Any ideas!

Would it be worth taking the starter motor off and checking it over?

Hi Rooster. I wonder how the battery was tested. It should have been done with a high discharge tester that would give the same load as the starter. As a quick test I would short the two big terminals of the starter solenoid together with a very hefty piece of short cable whilst monitoring the battery voltage with a multimeter. Be prepared for a spark, the starter motor should run. The engine will not start as the ignition is switched off. Make sure the bike is in neutral. The battery voltage will probably drop to 10V under cranking conditions, but should not be less. Be sure to use a heavy shorting link or you could get your fingers burnt. If the battery voltage drops to less than 10V then either the starter motor is taking excessive current (maybe an internal short) or the battery is not good. I think that will be a good starting point (excuse the pun). Hope that helps. Mike.

I've had a battery let me down before on a CBR600F - it was a NuMax......I suspected and swapped out everything else and it was that darn thing. It was a cheapie.......(false economy).
On a Superdream, if you want to stick with the original type battery (YB12AA), from experience (and low usage) I can highly recommend Yuasa or Varta to last at least a few years, more if used regularly or charged regularly.
The Motobatt are also a great battery if you can live with the colour of them - these are a glass matt type of battery and won't leak acid at all.

Could you try the battery in another similar sized motorbike , if you fly into Dublin today with the batter under your wing you can test it in my bike, be sure to keep the battery level by compensating the angle with gravity as during take off and landing!
