i went to connect my omex up to my s2 and the omex has a negative pulse but the rev counter needs a live

i know my s2 dials need a live pulse because i flicked a bit of wire conected to the green cable on the multiplug over a live and the needle moved up slightly but the omex 500 uses an earthed pulse to make the dials work

so are there any rev counters out there that will work with a negative pulse?

cheers! mr v

i thought they all used nagative pulses, cos it takes the feed from the -ve on the coil?

mrviper

my mate just said what about efi xr3i guages?

Damo V

think jim is right mate, just connect it up see what happens

mrviper

oki koki

think you will find if you have a coilpack, it wont read properly though... afaik, a resistor helps with this though

use the xr3i efi clocks like mr viper said

mrviper

are thease clocks hard to get hold of?

and would somthing out of a bob std EFI orion work because im not shure if the speedo goes as high and the temp/fuel guages are the same

turbo7

yeah the orion ones are the same as escorts and they should be easy to get hold of make sure the petrol and temp are the same as yours and the speedo is the same mate

mrviper

nice one i shal have a rummage around the local scrap yard then

thanks for all your help people

turbo7

no probs mate hope all goes well
