amperage doubts

["Paul Dorsey" <dorpaul@negia.net>]

  Hello again,
    I was told by the seller of this Ebay item that it will charge 50-65 amps?
A listee wrote, "only 34 amps".  Who's right?
    <http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=79586
79452&ssPageName=STRK:MEWN:IT>

    It's suppose to fit the following cars.  Again, the listee said,
'doubtful'.  Who's right?
    <(1975-72) Austin Marina 1.8L
    (1972) Mercury Capri 1.6L
    (1974-72) MG MGB 1.8L
    (1979-72) MG Midget 1.3L, 1.5L
    (1980-73) Triumph Spitfire 1.5L
    (1972-71) Triumph TR6 2.5L
    (1981-78) Triumph TR8 3.5L
    Ford Tractor Equipment
