Hooking up wires to battery, solenoid, altornater and starter

Hi from the uk if you look at startermotor solenoid you will see two large threaded terminals with nuts? and a third small terminal either spade or round terminal ok? now you should see thet one of large terminals already has a metal or braides strap secured to it and the actual startermotor body? LEAVE THIS ALONE the other large terminal is the one you fit the positive+ lead to from battery also there should be another lead to also attach to same terminal this one supplies power for vehicles electrics etc ensure you secure these with nut ok? now the third small spade or post terminal you will hav a thin wire nearby ?this attaches to thisterminal on its own on solenoid this wire is the one that activates starter when ignition is turned to key start position ok? as for interior light not working ? try again when you complete the above also make sure bulb is ok? ps! before you reconnect starter wires ensure the earth/ground lead is disconnected from battery and when reconnecting battery connect positive lead first then the earth lead or if you try other way you will have sparking from pos lead as you try connecting to battery hope this info is clear instructios for you to follow and wish you luck best wishes from england
