Hi Everyone. The A65 project inches ever nearer first fire up but there's a blocked carb problem which I'm sorting. However, when turning the engine on the kickstart (without firing due to the carb problem) I notice that the ammeter shows a negative current reading of about 4 Amps. I would have thought that as the alternator spins I should get a positive readout. When this happens only the ignition circuit is live, lights, brake light and indicators all being off. I believe the ammeter is wired correctly as it shows current drain with the lights and or indicators on (engine not running). I've fitted a 'modern' rectifier/regulator which is wired as per the circuit diagram in the instructions. BTW the bike is wired -ve earth. So why does the ammeter show a current draw when kickstarting? Would appreciate any advice/comments on this. Rob
Hi,
Is this with the ignition on? The ignition will draw a current even if you do not start the bike.
Dave.
With ignition on, as you kick it over to the right place to give it a bigger kick, the points will open and close , thereby drawing amps through the coil, usually about 4A.
The intent it fires, you'll get a + reading as the engine charges the battery
Thanks guys. That all makes sense. Just worried I'd wired it incorrectly somewhere. Just the carbs to sort and then I'll be ready to have a go at firing it up (fire extinguisher at the ready!). Wish me luck. Rob
