Anyone experienced a parasitic drain on an LC before?
Going by the wiring diagram, the positive terminal runs to the ignition switch and regulator/rectifier, that's it, so assuming that the ignition isn't faulty, when it's in the OFF position, the only item that's still getting juice is the regulator/rectifier, am I right?

No!
There should be virtualy no "grey" current draw. A modern bike running a clock and security LED will only have up to a couple of milliamps draw so an LC should be close to zero.
Can you conect an amp meter in series to the negitive cable/terminal? this will confirm ammount of current leakage.

Thanks, that's what I thought, I did do the amp meter test on the bike when I first got it due to the battery that came with it not holding it's voltage,...no reading so the battery were at fault in the end. I've since bought/fitted a new battery, worked fine for a few weeks then it dropped to just over 10V over one day/night, I then removed it from the bike, charged it via the Optimate for a few hours until the green light showed, then left it on the bench, checked it a day/two later and I got 10V again. Think that a cell might be down then?? I stuck the battery on another charger for longer on Thursday night, taking readings since then, 12.78, 12.66, 12.60, 12.53 up to now, I'll see if it drops closer to 10 in the morning, if not I'll put it back on the bike and do the amp meter test. |

A fresh battery should be around 13.2v

Rectifiers fail frequently. Get a MOSFET regulator. Anyone will work.

Defo time for a new battery... saving one like this is just putting off the purchase :/

Defo time for a new battery... saving one like this is just putting off the purchase :/ It is only a few weeks old! I'm guessing that it is a faulty cell, I've been checking it daily on and off the bike, it can read over 12V for 3 or 4 days then bang, down to 10V the next morning. |

Refund? if it's near new.
Early death is not that rare in electrical bits.

They certainly don't make batteries like they use to.
