    need help please i have a 24v 9 40amps) marine electric outboard engine, contolled by multi position switch,
    5 forward / netural / 3 reverse positions, the thing is i need to run another motor of the same switch,
    just to double up wiring would result in burning out the swich contacts, i know how wire up a relay to take away the load for the second motor for say forward switch postions, but for reverse the polartiy
    changes, so it acts as a brake, initially is this posible using one relay, hope this makes sense ish
    many thanks

    You need to make out the following yourself:
    • Wiring diagram
    • Set up a complete map with the connection between each wiring terminal against the others.
    See the attachment how to make such a connection diagram.

    To help you with the diagram:
    Kontaktdiagram = contact diagram
    Hauptkontakt = main contact
    AUS = off
    EIN = on
    Hilfskontakte = auxiliary contacts
    Startpos. = starting position
    Endpos. = final position
    Isolationsdistanz = isolation distance
