 Just had a gear down solenoid (bottom one in teh attachment) get hot/not
work/popped a 10a CB while checking operation before first flight ...   (The
'up' solenoid still works.)
 No markings on it, except a raised S and an I on the actuating terminals.
 Looks like a cheap item, and would like to replace it with something that
will NEVER fail... and should I replace the 'up' solenoid also?
 Asking for suggestions, before going to NAPA aircraft supply.
