Installing Tic-Toc-Tac w/Pertronix

Has anyone run into problems with either of the following:

1. Installing a tic-toc-tac in a car that didn't come with it originally?

2. Installing it in a car with a Pertronix ignition conversion?

I plan to buy the new tach and the required circuit board and just plugging them in. I'd hate to fry anything though...

I'm doing the same thing but I'm installing an MSD system.

Re: Installing Tic-Toc-Tac w/Pertronix

That would be three questions I have then cause I plan to do the same:

Has anyone run into problems with either of the following:

1. Installing a tic-toc-tac in a car that didn't come with it originally?

2. Installing it in a car with a Pertronix electronic ignition conversion?

3. Installing it in a car with a MSD 6AL?

Re: Installing Tic-Toc-Tac w/Pertronix

Well, let's see...
The tic-toc tach was part of the guage package, and also included the console guages. To do a "factory job" you'll need to buy the tach, the Console guages, the PCB, and the "guage conversion harness" which the repop companies sell to make it easier to retrofit factory guages) and a consolde harness for "gauge equipped cars"

Note: the tictoc tach has no idiot lights, so you lose (or make other arrangements for) your GEN and TEMP lights. In addition, the guage packaged replaced the original OIL light with a LOW FUEL light.

To do the tach without doing the guages, or perhaps with autometer console guages, is very do-able but will require some wiring fabrication.

It's also possible to modify the existing pcb, if you're both really good and really cheap.

The tach requires constant (battery) 12v, for the clock. This voltage is not fed to the dash cluster from a factory nonguage harness. The tach wire was installed outside of the harness, dorect from the tach to the coil. It also need ignition switch 12v, but this exists at the cluster connector now.

I've run the repro tictoc with a few ignitions. both points and MSD ready to run required a filter for it to work right, an accel billetproof did not need the filter. No specific info here on a 6al, imagine either will work but may need a filter.

Re: Installing Tic-Toc-Tac w/Pertronix

Jim,

I have autometer gauges installed and plan to replace my points with Pertronix.

It sounds like I just need to get a 12V power source for the clock, install the tic-tac-toc and PCB and then hook the tac to the coil.

How would I know if I need a filter with that set-up?

You'll hafta check the wiring on the new pcb, but yea, I used the tan wire that used to be for the fuel guage to supply power for the clock.

If your tach "hangs" at a certain rpm, or bounces or flutters, you need a filter.

Re: Installing Tic-Toc-Tac w/Pertronix

So...as long as I run a constant power wire for the clock, a wire from the tach to the coil and the proper ground, I only need the PCB and the tach to make the conversion?

Thanks again. I don't want to get the new tach and PCB only to find out that I need a new harness or something else too. Running 2 or 3 wires to power is simple and cheap...
