I assume you want to use a 120v relay as a contactor to take the burden off the
on/off switch. There’s ALWAYS 120vac available on the same terminals the
blower connects to. NEVER use chassis ground for a neutral return. Simply
hook into the blower terminals for 120v AC. Shift the wires from the original
on/off swith over to the relay contacts in the same configuration. The CW/SSB
switch is part of the on/off switch but is separate electrically. I assume
you’ll keep it as is.

Might be a bit hard to explain - so if you have/know this unit perhaps can talk
off line? I am rewiring the ON/OFF switch so the 220VAC doesn't go through the
switch. Using an AC relay (output/control side) - to Switch/connect the power
lines previously mounted to the ON/OFF switch. Then the ON/OFF switch is now
used to 'turn on' the relay - power to the relay - comes from the Filament
circuit via the ON/OFF switch to one side of the input/control on the AC relay
- and the other terminal on the input of the AC relay is then
grounded.Something just doesn't 'feel right' in having the one side 'grounded'
- and asking/wondering if a problem. Another thought is ? if I should use a
resistor of some value to decrease the voltage in this circuit going to the
chassis ground? Thoughts and experience doing this on this unit is
appreciated.73Larry F.W6EFLFibich@sbcglobal.net
