Hi ya thanks again for the help. I'm gonna use a inline switch to stop any loss when the bike is not running.
You say "measure the charging current at the 17V level, this will indicate the current capacity requirement of the diodes" how would I do this I don't understand 100%
Affter doing this how will I no what diode to use?
Thanks againm
Jim
hi Jim,
Regarding the inline switch, if you fit a blocking diode, you dont have to use a switch.
Do the following:
Disconnect the postive lead to the battery, with bike engine stopped.
Connect an ammeter is series with positive terminal of the battery and the wire you have just disconnected.
NOTE: if the ammeter shows a heavy reverse current when the engine is not running, it most likely means the battery is discharging back thru the generator. So the diode shown in the diagram should be fitted.
Choose a diode,,, 50V [or greater] 10amp[ or greater].
Set the ammeter to 10amps.[dc]
Start the bike engine and read the charge current on the meter.
Tell us what you read, then we can recommend a diode.
