Fuel and Temp Gauge

[AngeloEvs]

Fitting a 12V one will get your gauges working but they will read slightly higher than they should. The needles will also fluctuate as the Alternator voltage changes because all Regulators need a higher input voltage than their output to function correctly, in a nutshell go for the 10V. Either that or just wire link the regulator socket outer connections (that the regulator legs fit into) and run your gauges directly off the 12V untill you get a regulator fitted. The gauges will fluctuate and read slightly higher but at least they will be doing something in the meantime,

The one listed is a 10v regulator (and correctly priced for such a menial item!) but its not a direct replacement for the VAG (which is listed at megabucks price last time I looked it up). Check the spec sheet and I'm pretty sure you will find that the input and output legs are the other way round compared to the VAG one but you could fit it up side down but the Tab will not be in contact with the heatsink on the dash board which it must to stop it cooking. You could place a nut behind it though and that might conduct enough heat away. It was probably the equivalent I was referring to and saw mentioned in a previous thread. I would check the spec sheet before fitting it........

Heres the data sheet, legs are wrong way around with input on the left so fit it with the tab upwards and a nut behind it......

Good thing you are here AngeloEvs

It never occurred to me that VW (and others no doubt) would make a "special" 10 V regulator (with input and output legs reversed) when a common one is already so readily available Makes you wonder why !! (Thieving gits)

However, if it were I, I would buy the cheap one and reverse the regulator and make provision for heat transfer in the way you suggest

GSF have this..............

93681 VOLTAGE STABILIZER T25 5/79 > 11/90 8.95 (Plus VAT and delivery of course)

If it helps.

Its not just vw that use this voltage regulator, you will find the same thing is 80's Vauxhall dash pods too. Astra + cavilier for certain if you can find a scrap one.

I must be blind as a bat Grun, I looked on GSF and couldn't see it listed. Still dear for a regulator but cheaper than the prices quoted on the VAGCAT website...............

I never found it either, must have been spelling "STABILIZER" wrong!

OK chaps try...........

1. http://www.gsfcarparts.com/" onclick="window.open(this.href);return false;
2. Then select 'Shop' (Third from left on the top)
3. In the 'Part number search' panel ........GSF Part Number...... enter 93681...... then press search.

Or go ....'Search parts by vehicle'....VW Watercooled..... Type 25......category search........Switches senders and instruments........Search.
And third from the bottom of the list is.......... 93681 VOLTAGE STABILIZER T25 5/79 > 11/90 8.95

Cheers.
