Hello.
Here are some parts locations, see if these help:
Sorry they are not great screen grabs. The money shot is here:
The condenser fan motor(s) have a current draw of 6.5 +- 0.7A and the positive wiring contact is the one nearer the plug's release tab.
There's also this 20A fuse (on mine anyhow):
It's just to the left of the 'A/C Amplifier' (the computer) and is labelled 'A/C' so must do something, but isn't included in the above pictures.
The above screen shots come from RM156e. Sadly I don't know the title of the RM as page 1 is missing,
. It seems to only cover the L and RZ models and I've no idea if later engines different. Mine's a 'L' and it doesn't seem to be correct for it.
HTH
