(Fixed)


right its broke me now i need help

been looking at my rev counter looked all over this sight for an answer but still cant work it out why my rev counter wont work

this is what i have got

4x4 cosworth 1992 running wasted spark
it has a secs computer in and that has a rev counter on it as well

cant see anything wrong with the rev counter itself all looks good the rev counter on the secs computer is working fine it has had the msd mod to the back of the rev counter and the green wire under the bonnet are connected i get the same voltage there as i do under the dash about 0.5 volts at idle going up with the revs

need to know what voltage should i get at the green wire on the connecter at the clocks

and if its not working right why am i getting a reading on my secs computer

could it stop the revcounter on thedash working

help its driving me mad

cheers darryl

Have you spoke to msd?
Originally rev counter is from the coil which you no longer have . I am sure this is quite common.. Give them a call they are good and will help you..

dissmalrs

yeah have spoke to them and got the info about the mod they were really good
gonna try talking to them on monday as this is driving me mad

cant understand why its working on secs computer but not on rev counter

cheers for the reply

Dissconnect the suppressor from where the original coil was and join the cables together they are both green.

Your secs might work upto about 3k like mine, then goes to 0

I had a similar problem with mine when i first had wasted spark, mine turned out to be a problem with part of the wasted spark board, I've circled the part that was faulty, it had overheated, have a look at yours to see if the insulation has cracked on it, if it has i would speak to msd

Try either pin 3 or 5

I think it depends on what 'Firmware' your SECS has?

As I know there was an update planned for the tacho to work with WS.

thought i would update this tread

i finally pulled my finger out and got round to sorting this as karl pointed out it was the component that had failed

spoke to msd and they sent me one for free (twice as i lost the first one )

soldered it in and bosh working


thanks for the help and to stu at msd for his fantastic customer service
