NC30 clock change and no start.

i have, thats what i have been doing for the past 2 days. i leave it over night and usually it starts, but today....nothing. its on the charger at the moment. and the i can see that the battery is broken... the charger normally has a green light. but there is none so far. its either the battery dead or charger broken...

Stick a meter on the bettery while its on charge, if it below 12v with charger switched on, charger is prob dead, if its over 15v then battery is charged or nakered! But if its a smart charger it may turn itself off if it thinks its charged, they can be a bit of a pain sometimes!!

i think the charger is broken... the battery voltage does show 13.40v... but i dont know why the green LED on the charger is not on? it usually comes fully on when its at that voltage... never the less... i bought a new battery. the cells in the battery might be gone.

What wire is your "primary coil wire" to which you tried connecting the tacho signal wire? The ignition control unit output to the coils is capable of supplying quite a few amps and surviving hundreds of volts so I doubt connecting the tacho signal lead to any terminal on one of the ignition coils could damage it.

Do you have a manufacture's brand name for your battery optimizer?

i have the Oxford Oximiser 600, i bought a new Oxford Oximiser 900 today for 20 quid. gonna RMA this one back.

anway... well the Negative Primary ignition coil, is the rear coils, yellow/black wire. i connected the rpm signal wire that that... but i was suppose to connect it to, the Yellow/blue one, which is the Positive primary ignition coil. when i connected it to the negative, the bike cut out. and wouldnt start up properly.

In my earlier post, I suggested the blue/yellow wires as possible tacho signal points, no mention of yellow/black. My wiring diagram only has black/white and yellow/blue wires connected to both ignition coils, where did you get a yellow/black wire?

[xivlia]

the yellow black wire connects to the upper point on the rear ignition coil. it was there when i go it... the top connector is yellow/black and bottom is yellow/blue.

[magg]

Yellow/blue is the output wire from the ignition control unit which is why I suggested you connect the tacho signal wire to it. I can only assume that the black/yellow wire is actually black/white and therefore is the 12 volt power, via the stop/run switch, to the coils and ignition control unit. You can confirm this with a multimeter.

I do not see how connecting the tacho signal wire of your new instrument to the black/white wire could cause the ignition to stop, maybe you may have another wiring problem that coincided with connecting the tacho to the black/yellow wire.

Suggest you measure the voltage between the black/yellow wire at the coil terminal and the battery -ve terminal with ignition ON and stop/run switch in RUN position. Should measure same as battery voltage.

Correct me if I am wrong, your charger has 4 leds red, orange, yellow and green to indicate battery condition, a green led to indicate power to the charger and a red led to indicate battery reversed. Which green led does not light when you connect your battery?

[xivlia]

yes, there is green on the bottom left, and in the middle row there is red/orange/yellow/green. (bottom to up) the top green is not on, and it should be on by now. but the battery still shows 13.40v
