Noel,

I installed a secondard solenoid to compensate for my low voltage at the
starter solenoid.  It did work for about 1.5 years.  Then I started having
the same symptoms again.  The van wouldn't start when it was hot and the
electrical was heat soaked.  So I went and replaced the wire from the
ignition to the original starter solenoid.  It worked like a charm.  I have
no starting hesitation and I removed the secondary solenoid.  I recommend
using about a 10 AWG wire for the wire to the starter.  It's big but you
won't ever have a problem with it as long as your contacts stay clean.

Good Luck,
