Well mines completely being a P.I.T.A. now...
The dipped beam refuses to come on, full stop, when starting the bike after being stood for a few hours. Riding for 10 mins also does bugger all, unless the spots have also been on during this time. So, if I ride for 10 mins or so without the spots on, stop, re-start the bike, the dipped beam stays off. But if the spots have been on during this time, I then stop, re-start, they dipped beam comes on...
One thing I've also noticed, is that every now and then, the front beam seems to change brightness, so gets a little brighter, then a little dimmer, while it's on. Spots are off, bikes stationary, so not sure why this is happening...
I'm going to try running from a direct 12v source in a bit, try rules out balast issues (just incase running the spots is causing heat transference across the mounting bracket to warm up the other balast a bit so it works)
Ho hum...
*update*
Looks like Balast...
I tried to run it direct from battery, nothing... Started bike, nothing... So swapped over the power to the balasts so High is now Dipped), and the high beam fired straight up. Swapped it back to the dipped balast, and nothing... Did this about 5 times to make sure...
Attacked the balast with a hair drier for 5 mins till it was warm to the touch, and then it worked...
Grrrrrr
