Re: (ET) Dan's 2/10A charger

[David C Robie <mycroftxx1 juno com>]

Last time I looked at the price of springwould countdown timers they were
bout $25, and long interval or solid state, more.  That kind of money
would certainly be better invested in a Landis.   The plug in type is for
the rest of us (like Swamp Yankees) (that's the worst kind) (like myself)
who do stuff like this quick and dirty without a trip to the electrical
supply place.  Contacts on the air cond types are rated at 15A.  Tractor,
at start of charge and for a good while draws about 17.  In several yrs
of use and abuse by being outdoors in an 'acid fumes' environment have
never welded contacts on one.

Can't blame a 30+ yr old GE timer for going bad.  Especially in these
'enlightened modern days' of throwaway electronics, grounds maint
equipment, and even fullsize motor vehicles.
