Working on electrics

[nigel cross]

Whilst searchig throu WIS they keep mentioning that before starting any electrical work and disconnecting the battery, you fit a quiescent current retention unit accross the battery connections. I persume that this unit which looks quite small in the diagrams is in fact a small 12 volt battery. Has anyone any experience of these units, ie the current capacity in amps?
