Well, I'm not sure where to start.  Some of these devices are very 
simple.  really just a big transformer and some diodes.  Maybe a 
mechanical timer and a meter.  There should be a circuit breaker in 
there as well.  This type should be relatively easy to diagnose with 
a voltmeter.  Some more "advanced" models have electronics inside.  A 
circuit board "brain" that controls the rate of charge, etc.  One can 
still check the basics with a voltmeter, but if the fault is in the 
electronics it may get a bit more difficult.  If you figure out the 
exact model numbers, you may be able to search around for owners 
manuals, schematics and parts listings on the web.  If you think that 
you're in over your head and you have a bunch of these to work on, 
perhaps the best thing would be to find someone to help.  Maybe a 
student who's into electrical stuff.  My son would be glad to do it 
if you were nearby, but PA is a little out of range.
