    I am trying to locate the identification of the breakers and circuits fed from each for a 1989 FLT Classic. I have the FSM and what Harley calls a wiring schematics is worse than useless. I am in the process of using the ignition switch circuits to control relays to take the load off the weak and now unavailable ignition switch. Any help is appreciated.

    Normally the Main breaker is a 30 amp.,Ignition,Lights and Access. are a 15 amp. breaker. If you notice one stud will be copper colored for the Power side and the other is a steel color for the Load side. Hope this is what you were asking.

    I am actually looking for a little more detail. Example- I need what breaker 1 controls, breaker 2 controls, and so on from left to right. Like previously stated the factory manual for this year has the worst schematics I have ever seen. I can figure this out with a multimeter given enough time but if someone has done this already why re-invent the wheel. I know the riding community has always been helpful in the past.

    Your bike is an 89 you don't have to be real cautious here. Just remove a breaker and see what doesn't work.
    Much quicker than a whole schematic test. Sometimes simple is good.
