ignition override,
if i'm not wrong, on the b737 classics, when on battery power only, the standby instruments, engines indications, left IRS, dome light, some intergral lightings, plus many others will be powered. some airlines even opt for left EFIS to be powered.
but a small torch cant hurt esp. with guys from the old 'jurassics' (dont know how the sys works though). remember a couple of years back, there was a SB from boeing to check all batteries on the b737, apparently some of them dont live up to the 30 mins claim !!
