Well in 39Yrs of working on these I have seen the Improvement that an
added relay can provide so Perhaps You just haven't been working on these
Long Enough ~

While Agreeing to Disagree is Ok to apply to a discussion of Subjective
Opinions, this is not that ~ The addition of a Relay to the 50Circ' can indeed
provide a more efficient path for power to the Starter Solenoid & Eliminate
unnecessary degradation of the Igni'Switch & Connections & Wires in the OEM
50Circ' ~
I suppose if You feel that this is about whether OK is sufficient vs Better
then We can agree to disagree ~

The Relay is not a Bandaid,
It Is The way the Circuit Should Have Been Done In The 1st Place ~

So far what I am finding is that Initial Current to extend the Solenoid can
be in the 25-35Amp range & then it will drop to 8-12Amps during the remainder
of the Cranking to Start ~ While Relays appear to only have Needs in MilliAmps ~
Still looking ~
> Wires don't 'get tired'.
Perhaps "tired" was the incorrect word to use ~
"There is a wearout mechanism in metal called electromigration. The failure
typically relates to high current (electrons) moving metal atoms resulting in
voids (missing metal atoms or a hole in the metal line). This failure typically
appears close to the contact area and not in the middle of a wire."
Corrosion also causes a wire to be less efficient & I suspect We've All seen
that ~
