MAK, personally I would try to find what's causing the drain, so this is my suggestion:

As Slick said connect your meter in series with the battery. Make a note of the drain you see.
Then open the speedo shell, and disconnect the 8 way multi connector plug to the speedo while watching the meter. If the drain drops you'll know it's probably a bad guage, but to double check plug it back in and then remove the other plug and again watch the meter. If it drops again it probably isn't the guage at fault, but something further along the circuit. If there has been no change at any of these steps, try the same on the rev counter.

If none of these have made any difference, pull each fuse until you see a change then consult the wiring diagram to see what connected on each of those fused circuits. Once you know which is the culprit start unplugging components until that reading drops.

A friend of mine spent days trying to isolate this kind of problem. He was convinced it was the loom at the headstock so he removed and opened it all, but found nothing wrong. He eventually found it was a badly manufactured stop/tail bulb !!

There are those that understand electrics and others!!!
Must be the other.
I will give it a go meter in hand with a large probe.
No laughing at the back Mr Estuary.

That's pretty handy, but you'll hopefully only use it once. A multimeter will do the job. Do you have one? If not the money would be better spent on one, as you'll find other uses for it.
