Would you be able to point me in the direction of this schematic?

Also, I have a related question. I have a T45 plus battery plus charger.
The battery is dead. I left it on charge for 8 hours and then it took
ages to get ready to fire (the ready light didn't even come on) but it
did manage one emission. What is the best way forward to get this back
working? Can I "rebuild" the battery myself (with rechargeables), or do
I need to send it away, or am I best off just trying to "fix" it with
non-rechargeable batteries somehow and junk the charger?

Thanks,

Simon
