If you are using a HD F&R install the switch now using the hardware you saved from removing the original. I'm using the SW182 reversing contactor so we will begin with some bench prep, installing the very important voltage suppression diodes now.
NOTE - the small terminals are marked + and - . Can anybody tell me why this is ?
As you guessed, the coils and the diodes are polarity sensitive. Get these wrong and you make trouble !
I am mounting this contactor in our demo model using a black L bracket. Later models used a silver bracket. The unit mounts on or near where the old solenoid mounted just below the old F&R location.
NOTE- mounting components where and as shown here insures our cable set will have the right length for the 1-8 numbered cables in your plans..
If you are making your own cables mount stuff were ever you like and try to keep the runs short for best results.
