Switch the ignition on but do not start the engine, have someone look at the volt meter where the red light should be and then go to the rear of the alternator, there is an oval plug with three wires, or a square plug with four wires (but this is rare), what I have seen is a square plug with three wires, these are alternative alternators when one with an oval plug version is not available. Gently give the wires a shake and gentle tug, more often than not the red charge light by the voltmeter will flicker, get a new plug with pig tails and solder it on, DO NOT USE CRIMPS or the little blue wire joiners that you put on with a pair of pliers, the combination of aluminium and copper wires sets up corrosion in a short time, and you will be back to square one.
If there is no light do as per @Grimbo with the exciter circuit.
I seem to recall there is a fuse for the ignition system, are all the other lights expected to show on the dashboard with ignition on? I would look through the wiring diagram yourself or perhaps someone else would? I do not have the patience to go through it, I am not being rude with what appears as a 'can't be bothered' attitude but my grey matter is still recovering from surgery and a wiring diagram might as well be a bowl of spaghetti to me.
There is no oil PRESSURE light but there is an oil LEVEL light, and there is of course the oil PRESSURE gauge, I actually put a 'T' in between the block and pressure sender and wired it a light and buzzer, if you hole your sump and lose your oil, damage will be done long before you realise it.
