Thanks Rob - much appreciated! Best wishes - Simon

Thanks for your help Gland and Rob. I'm assuming that the two white wires on the Rev counter go to the coil/distributor. The green is presumably earth, the red the power source for the unit and the red/white for the internal bulb. My concern is whether I could damage it if I connect the two white wires incorrectly. So one goes to the -ve on the coil, not 100% sure what the other attaches to... are you saying the small lead that goes to the distributor? and will it matter which way round they go? - as you can see, they both look similar. On the Ammeter, that does seem straightforward - so really appreciate that - thanks again :-)

I have Smiths analogue ammeter and rev counter from 1960s/70s. I'm not sure how best to wire them in. They are going into a Triumph Herald 13/60, which runs off a dynamo and has had no conversions - any tips? Thanks Rev counter Ammeter (the wires that are in pic are obviously for the night time illumination - it is more a case of how to wire so I don't have to run the full current across the instrument).
