If you got a chrome welded-chain steering wheel and a Mexican blanket car seat cover, you'd have a whole new look...

Have a look here www.westach.com
Lots of combined gauges mostly intended for aircraft but will work in a VW.

Thats the link to my members ride bit, i have one, it works well, ive got the water temp in tinware so i can moniter the temp of around the heads,
instead of cylinder head temp as this was much easier.
Oil pressure is hooked up in a t joint for the stocko and this one.
The volts is hooked up and works well.
The tacho goes good, got a switch for 4-6-8 cylinder motors and i can change the light of the background and set where my shift light comes on.
Only issue i had with it was it needed a corrector diode from dick smith in-line to get it to read accurately.
Pm joel for the part number, i cant remeber but they are only a couple of cents.

jus need a sombero,............... the diode was needed because the tac was innaccurate, what is a diode and how why/how does this fix the problem.
did the tac already have a broken diode?????. also are internal guages easy to read with the tac needle bouncing around

Hi
I fitted a 2 inch VDO tacho to my son David's bug, it was reading inaccurately, I thought it was switched wrong but it needed a diode as well make it
read correctly.

maybe cleaning the signal a bit?
coz most people connects it directly to coil (-ve)
there are some spike happening there

Joel has said before when i asked this same question, i think it has something to do with the coil info being sent.
Its just something you put in line with the signal wire and it stops the needle bouncing around and makes it move smoothly and accuratly.
They are preety easy as oil pressur eis the only one that really moves around that much while driving and my needle only gets that high in the wet.
Volts bounces around a fair bit on mine as i think my regulator is on the way out.
But the onl bad bit is the shift light. It isnt as bright as id like, but i guess it shouldnt be on for as long as mine has been when we go out on a
mates paddock.
All in all its a good tacho and i will be installing one in my brothers charade in the next week.

it just cleans up the signal
Unless you pay big $$s for quality tachs like Autometer etc most of these tachs just come from taiwan and there made to run on your average boy racers
rice bucket with a ECU generated tach signal
Theyre usually not sensative enough to work off the fluffy signal that points make
THe diodes only work one way, if you get no signal flip it around
and also i put mine at the coil end which was probably a mistake cos it failed fairly early and i think it was heat.
stick it up front at the tacho end

It might need the diode as when the electromagnetic field in the coil collapses it generates a back EMF. The diode will block this.
(I think, I'm a bit rusty on electronics these days)
