Do you have an alternator which has an external regulator mounted on the LH inner guard (as per original) or do you have a later version which has in internal reg ?
If you have the later style unplug the brown wire from the rear of the alternator, switch the ignition on & short the brown terminal to earth. The red light should light up. If it does light up, you have a problem with the alternator. If it does not light up, your problem is with the globe or dash wiring.
If you have the external reg set-up, unplug both the reg & the alternator & short the brown wire to earth & the above will apply. If the light does light up, your problem could be either alt or reg.

The brown wire needs to be plugged in to the alternator.
Make sure it is and get back to us.
You should be able to work out which terminal it needs to go on by the plug on the regulator.
It wont hurt anything if you get the wrong terminal on the alternator though.
Ass you me. How hard can it be to test the dash circuit.

Battery probably just needs a top up. Take it for a drive, you'll find after a short while the charge rate shown on the gauge will drop. Unless of course you have some high demands on the power supply like a thermo fan operating or a thumping audio system etc.

Disconnect both the large wires from the Amp gauge, join them together firmly with a short 3/16 bolt or similar and make sure you tape the join up really well to insulate it from the surrounding bits.
Change or modify the AMP gauge to a volts gauge and life will be good again.
I've modified heaps of Amp gauges to Volts (including the dial) and most people wouldn't notice it was changed. It's a common mod, unless you're a stickler for originality.
At some stage in the future, if you put in a larger alternator, and your system is drawing more than 30 Amps, the internal shunt on the Amp meter will overload and then there is a risk of fire.

No real risk at the moment, but if you were to add say, thermo fan, big stereo, driving lights and headlights on all at the same time, that might be too much.
With what you have now, it's fine, because the alternator is only 35 amp, so the regulator will keep it safe.
I was thinking more as to when or if you upgrade the alternator or add lots of stuff.
