Rewiring from a rats nest of off color taped up wires is more of a process challenge than a technical one. Bob M wiring diagrams in the archives (search for box above), and a manual will be essential (top left on this page)
Solenoid wires
Hs have various starter mechanisms. None (to my knowledge) came with a solenoid. If you hav a push button start, or a key start system, here is your answer. Change to a 12 volt with 4 terminals. looking from top down with the terminal end of the device away from you, put the battery cable connection, and the power wire to the amp gauge, on the left terminal. The next terminal is probably a small one labeled S this gets the wire from the key or push button to start the tractor. The next terminal is probably labeled I it is to be connected to the coil side of a ballast resistor (if your coil is designed to ues one, or you are using the 6v coil which needs the ballast resistor Mid 60s chev, or chrysler will work).
If your 12v coil is labeled "no external resistor required" then leave this terminal naked. If you have a ballast resistor, or are going to use one, the wire from the Key or "on off" sw that powers the coil should hook to the other side (non-coil side) of the ballast resistor)
The purpose of the I terminal is to bypass the resistor when starting to allow for voltage drop from the starter, giving a hotter spark at cranking. Good luck I hope it helps,
