Hey this must be here some place but eludes me.
I have searched but can not find this modification to install the lithium battery.
You help would be a great............

Looks like you'd just need something to attach to diode D39 (and ground, obviously)

Thanks BugBrand

Okay, but wasn't there some kind of capacitor too?
I really need instructions to follow as my DIY is noobit's and I'm sacred.
It gets pretty dark with power for me.........as you can't see it but it's around.

I hope to be a tough DIY'er one day.

I don't know why a cap would be needed too?

Couldn't find any step-by-step, but there's many refs to adding a battery just by googling - or you can get a kit from AS for £20... (presumably that'd come with clear instructions etc..)

Hey Thanks Bugbrand yr cool, I did look around google and didn't find this until you placed the search list, nice one.

Oh it's a diode in needed, oops

1) connect the (-) of the battery to ground.
2) connect the (+) side of the battery to the anode of the diode, then connect the cathode of the diode to the node labeled BU (backup) in the service manual. This could be the cathode of D38 or D39, C27(+), or pin 18 of one of the memory IC's.

For the lithium cell you can use anything you like obviously, although I'm partial to the 1000mAh size coin cell w/ leads such as Panasonic BR-2477A. This fits well standing up in the area just below the bass/snare level controls. Another high capacity size that'll last forever and fit nicely is the CR1/2AA size.

Sorry to bump an old thread - does anyone know what kind of diode could be used in reference to the post above? I searched high and low to no avail. Thanks in advance for any help!

Any generic purpose diode should do the trick. 1N4148 or 1N914.
