On this diagram, the starter will have a saddle switch in stead of a solenoid. The bypass wire shown can be hooked to the big terminal on the saddle switch on the starter, and the ballast resistor as shown, but there must be a diode placed in the wire with the band end toward the ballast resistor to prevent back feeding the starter from the ignition.
The lights are supplied with voltage from the key side terminal on the amp meter.
The amp meter must be changed so the wires are on the opposite terminals to allow it to read correctly with negative ground.
Observe all polarities as shown. If you have more questions, ask. (I assume it is a Hitachi alternator), Note the marking equivalencies: if Hitachi, the S terminal is the same as the #2 on the diagram, and the L terminal is the same as #1 terminal. If it is not a 10SI or Hitachi, do not follow these instructions, let us know. Jim
