Thats not sounding good!


I REALLY hope/think it may be the battery because it started first time on the button with jump leads! I dont understand why it hadnt sorted itself after a ride though. Is it as said above that once its gone a bit it wont come back?

its hard too tell from what you say in your post.
if you have meter tested the batt while running and its putting 14 - 15v back in then its not the alternator.
check the bat after it has been left for a while or even over night to see what voltage is in it. i.e. is it retaining its charge.
and finally if all the above check out, it sounded to me that what you described as a whirring. would be the starter clutch spinning without engaging.

Its more like a buzz. If i put my hand on the componant i can feel it vibrating ( little round thing in front of the battery between it and the starter motor! Has a white sticker on it with a jap brand Hitachi??? or summit)

try bypassing it then to see if it is the starter relay.
long handled screw driver across the terminals to bridge it.
watch it though it can make you jump

Is that connect the 2 bic connections or the pins in the little white connector?

keefer 10-Jan-2005 20:35

hold on ill take a pic then post it

fanks matey i cant wait:D:D:D:D:D

ok its a poor pic but the round thing to the right of the bat is the starter relay. on the back of it there are two large connectors 8-10mm nuts and the bottom wire leads to the starter.
ignore the small connectors you mentioned that's what sends it the signal to get busy from the starter button.
Bridge the two large connectors. But again be careful it will spin up as soon as you cross them with the screw driver. if it turns over moor than it has been then bobs your uncle

12.5v t idle but not over 14.5 if it is charging over 14.5 it will ruinthe batt.

But ccould it be you trickle charger is faulty and has to higher output ????

would still say it's the batt s if it's not charging then with the electric fuel pump and injection system all needing power you would not have got 50miles :biaggi:

But you could always buy a petrol slave starter motor :lol:

With respect, i wouldnt go sticking a screwdriver anywhere in it!
In fact im sorry but, it infuriates me to read some of the advise given.
I know we all want to help, but, please............. My advise would be to only take the advise of our well known learned friends, or better still, take it somewhere that knows what they are doing. :eureka:
