[TR] TR3A Overdrive Wiring

[Geo Hahn]

A tip I picked up from this list was the addition of a Slow-Blow fuse
on the circuit powering the solenoid.  I used an 8 amp fuse.  The idea
is that this will allow the strong pull-in coil to operate momentarily
(as it should) but will blow if the internal switch controlling that
coil fails to cut out -- thus protecting the solenoid from damage.

Explicit details available to the curious.  Possibly worth doing while
one is in there with the wiring.
