GazW Posted July 8, 2011 Posted July 8, 2011 So the CG wouldn't start on the button this morning at the girlfriends house, I managed to bump it and it ran fine. On the way back to mine, I switched the bike off at a set of lights (nothing behind me, it was around 6am) and the bike started on the button fine. Rode back to mine, couple of hours later... Same problem, wouldn't start. The starter motor was turning the engine over... Just. Not enough to start the bike though. Had to bump it to get to work. Then just had to bump it to get home from work, when I arrived back at mine I killed the engine and then it started on the button twice...I have just connected it up to the battery charger, and it was barely lighting the second red light (oxford charger, two red lights, one amber and one green) after being on charge for 30 or so minutes it has risen to green. Would I be right in thinking the alternator is charging the bike and the battery is losing its charge, due to the fact it will start after immediately after being run. I know I could do with a multimeter test when the bikes running to check the voltage but my dad is on holiday and his van is locked up at his place of work, so I can't get to that. Any help much appreciated! The bike is run every day without fail Quote
eastanglianbiker Posted July 8, 2011 Posted July 8, 2011 sounds like the battery could be dieing put volt meter across it with engine not running and with it running to check out what reading you get as it could be reg/rec over charging battery and boiling it dry of acid so check voltage if readings are fine then new battery time by sounds of it Quote
GazW Posted July 9, 2011 Author Posted July 9, 2011 Well I had a voltmeter on it this morning. 12.5v with the ignition off, when switched on the battery started falling to 12ish, then tried to start it, dropped to 6v. Bumped it and checked the battery and it was 14.09does that mean the battery is knackered? Quote
Colin the Bear Posted July 9, 2011 Posted July 9, 2011 Either battery is done or starter problem. Alternator seems to be working Quote
GazW Posted July 9, 2011 Author Posted July 9, 2011 Well considering that a starter for the cg is £370 including vat (deadly serious) I may take my chances with a £20 battery and hope that cures it! Thanks for the quick response Quote
