How do you lift the locking bars on electrical connectors without
snapping them off?
I may have a corroded terminal on my alternator (idiot light can be
made to go on/off by wiggling cable to alternator), but know from EGR
circuit repairs that these locking tabs are now brittle and break off
if only slightly over-flexed.
The cold will only make them even more britttle.
