I was thinking about getting a smiths rev counter but I will have an accuspark electronic ignition. So do Smiths rev counters work with an accuspark electronic ignition.

they get their signal off the coil so should work

Depends on the type of smiths - RVC or RVI...

older smiths rev counters dont work with any mods to the distributor, later smiths rev counters work off the coil so will work with pretty much all mods

Sorry - no.
RVI and RVC Smiths rev counters each work off the coil, however those stamped RVI on the face of the tach are "induction loop type". These will not work with elec ignition. Those marked as RVC will. Please be more specific in the type proposed to be purchased - i cannot confirm which type you are buying from that photograph.

Write the seller and ask if they find RVI or RVC printed on the gauge face. OR... have them send you a picture of the back of the gauge. As stated by L400RAS, you want the RVC type tach, not RVI.

I am using a Smiith's RVI with electronic ignition.

It may not work in all cases but on mine it was:

Green and Black to earth
Red to fuse box
Red with trace to dash lights
White and White with trace wired in series with the coil (polarity matters so if it doesn't work the first time, switch the wires)

Red wire from electronic ignition to + on coil
One white wire to - on coil, other to black wire on electronic ignition.

The online description I got it from was using a 123 ignition but works with my Ignitor as well.

Congratulations Keith. You are the second person I know who has been fortunate enough to have an RVI tach that works with their electronic ignition.

I stand by my earlier statement though. If you are buying a Smiths tach and plan on using electronic ignition, buy the RVC type.

For another link, read the one posted below for Speedy Cables regarding the RVI type tachs. In particular, notice the VERY bottom of the page where the link points out that to use the RVI type with electronic ignitions requires a conversion process. I was serious with my congratulations to Keith. He really is only the 2nd person I know whose RVI tach has worked with electronic ignition.

Rvc work. Rvi won't with the leccy ignition
JDO instruments will convert them for you though for £55
