Wiring up a tacho to a 6V bug
Dannyboy - May 25th, 2004 at 07:37 PM

What do i do? Asks for a 12v source!

Why has the motor more than 5000 rpm ?


BettyBoop - May 25th, 2004 at 08:20 PM

I'd love to know how to wire up a tacho to a 12v system :D so go for it! :D any one?


hehehehe

Does the tach tell you how many amp's it uses as a 12v unit and has it got 3 or 5 wires


seagull - May 25th, 2004 at 08:28 PM

in side does it has a switch 6 volt /12 volt ? the one in my shed does

you can always purchase a 6v-12v converter.


Dannyboy - May 26th, 2004 at 09:16 PM

It's a moon one , only as switch for 4,6 and 8 cylinders. Someone must have done this before! The wiring is simple enough just need to know about the power source and what i have to buy.

Pod where did you buy yours from?

Dan:)


Desert Moose - May 28th, 2004 at 10:22 PM

Hey Dan are you sure this will work because the converter will power the tacho up ok but what about the power from the dizzy? It still will be 6v not 12v


pod - May 28th, 2004 at 10:28 PM

a guy up in Brisbane i think you can get them from Jaycar but about $150 but dont quote me on it

Hi

How many connections does it have and what type are they.

I have Stewart Warner tacho in my bug now (it was in my 1st bug in 1971) that only needs an earth & - from the coil, no voltage input. So it would run on any voltage.

Dannyboy - May 28th, 2004 at 10:50 PM

4 wires , this is what it says on the instructions

Black - to negative battery terminal or good chassis ground

Red - to switched 12v circuit at fusebox or splice into a wire which is engergized when ignition is on

White - to panel lights circuit at fusebox or splice into any wire connected to the panel lights circuit

Green - to the appropiate vehicle tachometer source

What do i do?

Dan:)


1303Steve - May 28th, 2004 at 10:56 PM

Well it looks like its a good time to do a 12 volt conversion.


Dannyboy - May 28th, 2004 at 11:15 PM

Thats going to happen when i get my new motor & box but thats not for a while . Will have to get a 6-12v thingos that pod was on about

Dan:)


Dannyboy - May 28th, 2004 at 11:20 PM

Has anyone used a converter and ran a tacho from it. Desert Moose has a good point!

Dan:)


matara - May 29th, 2004 at 12:12 AM

I have a VDO tacho thats 6v. Its from an old BMW from the early sixties but its very close to a VW one. Very nice unit.

Let me know if your interested and I'll dig it out and work out a price.

Cheers

Steve


Dannyboy - May 29th, 2004 at 05:58 PM

Okay managed to track down a converter but the owner ran a stereo and other gauges and not a tacho. So all i now need to know is where to put the wire on the coil and if it's going to okay as it's a 6V coil. Help please!!!!

Dan :)


Dannyboy - May 31st, 2004 at 10:05 PM

Anyone know?

The connection to the coil is only for the signal to the tacho. This pulse will tell the tacho how many rpm you are doing. It will not damage the gauge to connect to a 6v coil though depending upon the tacho you might not get enough voltage to get a reading.
Is worth a try to see what you get.

the tacho has 4 wires , ground , lighting , coil and 12v source. I can get an inverter for the 12v . So you reckon it's worth hooking it all up and seeing what happens?

Thanks Dan:)


Dannyboy - June 1st, 2004 at 11:14 PM

Desert Moose it doesn't say how many amps it uses and has 4 wires as mentioned earlier in the thread. Here's a pic of the tacho anyway!

Yeh give it a go with the inverter to see if the pulse is strong enough. make sure you keep the light 12v as well and run it off the inverter.


Dannyboy - June 2nd, 2004 at 07:02 PM

Cheers should be able to manage that!
