Rev counter for old Triumph.

[St George]

Does anyone do an electronic rev counter for old twins that run on 12 volts. I am currently running on Pazon Mark 8 ignition with modification by Kirby Rowbotham. Not looking for anything that looks period, just functional. Thanks.

How do these systems pick up the engine signal or do I need a pick up kit as well > Thanks.

I’ve got one on my 650 with electronic wasted spark ignition and it works well.

There are prettier things like this: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F233107254803

I had one working on a signal from the alternator, but I didn’t isolate it from vibration and it broke.

I just put one of those cheap chinese £7.50 ones off ebay on my bullet.

Remarkably, it works, but reads double because of my wasted spark. I dismantled it with a screwdriver/tinopener and found a pot inside which I twiddled all the way to one end and it seems right now.

3 wires. Switched live, earth and a take-off from the coil LT side.
