Hi Guys!
This topic might have already been discussed - sorry to bring it up again...

I have a dual fire electronic tach (Analog faceplate). The UCE ignition is Single fire. There are single fire tach adapters that can be used for Twin cylinders - which should have 2 ignition coil (right?)

In our RE, it seems like we have 1 ignition coil. The single fire adapter that connects to coil has wires for coil#1 and coil#2. In this case, considering RE has 1 ignition coil, can both coil#1 and coil#2 be connected to the same ignition coil negative?

Will this show the proper RPM?

Also essentially these adapter are 2 diodes with parallel resistors across each - allowing current to flow only in one direction.

Please let me know if any inputs...

Thanks,

           I don't think the UCE is what I would call single fire.

            I believe the UCE fires the plug on both Power stroke & Exhaust stroke. That is not single fire.

             A single fire ignition system fires only on the power stroke & on my harley would require 2 coils & a whole lotta other money   

             Here's what I would try with your tach: I would hook up the 12V wire, start the bike & touch ONE of the tach's coil wires to the Enfield's coil & see what happens. Whatever happens will tell you what to do next. I'll make a S.W.A.G that the tach will work.

              But godknows, I've been wrong before. That's how I've learned so much from my mistakes.

I know there is modern looking tachs, but has anyonre found a good looking 50s style?
