A little advice if you would,

my 85 westy has an intermittent starting problem where the starter will not
turn.  I know my batteries are good (tested).
I hear the fuel pump but nothing else.  It can happen when cold or hot.  If
I walk away from it for a bit and try again later it usually cranks (haven't
gotten stranded anywhere for too long yet).

Does this sound like a starter solenoid?  Anything else short of a new
starter?  Is the solenoid even replaceable?

BTW - the cables are all securely terminated on batteries and starter

Thanks in advance,

Juan
