[Ducati] batteries

<SNIP>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Rich(s) and Stuart, thank you for your help.  I currently have
a 12V Yuasa
4AH, one cell seems bad, so I am looking to replace it. The
funny thing, the
bike starts on the first kick, but dies when you apply the
brake: in effect
I have three kill switches: headlight switch, brake-pedal
(that one's
dangerous) and key.

What I was wondering, was whether the charging system would be
taxed by a
higher (e.g. 18AH) battery, as I prefer riding hi beam ON.

I started out in the spring with a 3Amp 12v battery in this bike;

It was struggling so I opted for a 12V 9Amp from Walmart. It
will run for over an hour with the lights on but nut much.
Runs forever without the lights. The 60watt alternator shows
an increase in voltage across the battery terminals when
revved but not much.

I think Phil Hitchcock at R&R was doing up an 18amp high
output alternator kit but I haven't heard about it lately.

What model is your bike ?
