help with old rev counter for rev burner
« on: October 23, 2011, 08:37:18 pm »
Hi all!
I'm about to order a rev burner for my first simracing project and i would like to ask the community for some help with the tachometer. A friend of mine (with even less idea of electronics and mechanics than me  ::)) gave me and old tachometer his father used a lot of years ago when i told him
about the project, and I suspect it is not suitable for rev burner 'cause there is no blue/green cable for coil, only red and black cables are present. So my question is if it is a mechanical tacho and I will have to look for an electric one. A couple pictures:
Front view:


Rear view of tacho:


The black piece is for the bulb, and sadly, I have no instructions on how to wiring as my friend's father passed away some time ago.

Thanks in advance, and sorry for my English  ;)

Hi.
I don't think it is a mechanical tachometer bu gI can't see where to connect the signal wire.

Maybe to one of those unused screws?

Hi Cristiano, I thought the same but those screws seem to fix the rev counter to the case. This weekend I'll speak to a friend's father who may know how to wire this rev counter, if I get any instruction I will post it here.

Hi!

If i remember good, you see where the black wire is, the little fork there, you had to loop a wire from the coil or the cap distributor to get your signal. So i dont think you will be able to make it work with the rev counter. You might want to look for tach conversion, if you want to keep the vintage style.

“HORSEPOWER” is how fast you hit the fence.
“TORQUE” is how far you take the fence with you.

Hi all!

Sorry for the delay in answering, I had some health issues (now I'm ok again  :D).
I Just wanted to tell you that I finally could connect the tach to the rev burner with a friend's help, but I didn't worked right, so I assume that the tacho is too old and won't work anymore. So thanks to all for helping, especially to Dennis who gave us the right clue.

Regards
