If the air gap in the declutchable fan is bigger than spec. You will
still hear a click with engine off and power applied to it but it may not
pull in reliably when engine is running. Another thing to check is
binding of the carbon brush. Make sure the brush is free to move by the
spring behind it. Another thing is to make sure you have a good
connection at the carbon brush and the wire going to it. When in doubt
replace it.
I do not have a turbo 505, never worked on one. According to the elec
workshop manual both fans run together, high or low speed. Low speed is
done by putting both fans in series through relay logic. In your case
you may have found the problem with the bad relay.
