Some what I refer to as Ford type starter solenoids as well as some GM and some tractor solenoids have BOTH a small "S" terminal plus an extra "I" terminal. Normally S is the solenoids activation terminal which if voltage is applied the solenoid engages/closes and voltage is thus applied to the starter motor. Normally I is hot ONLY when the S is activated and its purpose is to feed battery voltage (i.e. by passes ballast resistor) to a 6 volt coil on a 12 volt tractor for a strong starting spark but its dead/open when shes not cranking.
If your solenoids I terminal is hot all the time theres a problem since on most its hot ONLY when the S is activarted and the starter motor is cranking.
You need to unhook the wire on the I terminal and use a meter or test lamp to see if I is actually hot ONLY when the solenopid is engaged orrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr if shes not wired right and that circuit (the wire you unhooked off I) is getting the wrong hot feed elsewehere???????????? that wire is usually hooked to the coil so the baLlast is by passed only while cranking.
