I’m checking dash ground first thing after much good advice, especially about not assuming it’s OK. Both indicator lights work. My tach was acting funny.

<div><font size="2">Usually the first step would be to bypass the dimmer rheostat,
which may not be as easy on a padded dash as on the UK dash. They usually
have double spades for each connection, with two wires in a single spade on each
connection, so it is a relatively simple test to move one of the connections
across to the spare spade for the other connection.</font></div>
<div><font size="2"></font> </div>
<div><font size="2">Have you tested the bulbs work out of the
sockets?</font></div>
<div> </div>
<div>All the gauges should have earth wires on a 72, you can't assume the dash
is earthed. There should be a black wire under the fixing nuts that hold
them in the dash, or could be a spade on the back of the tach case. That
is fed from a 4-way bullet connector that also feeds the right-hand indicator
tell-tale, does that work? The left-hand is fed differently.</div>
<div> </div>
</font><div><font size="2">Does the tach work as it should? If so that would appear to have a
good earth and it's bulb should work at least. Are you looking at them in
low light levels? You won't see gauge illumination if the ambient
conditions are bright.</font></div>
<div><font size="2"></font> </div>
<div><font size="2">Did you only have one bulb unscrewed when you tested for 12v
in the socket and all the other bulbs screwed in and fitted? You need to,
especially if your test light has an LED or you use a voltmeter.</font></div>
<div><font size="2"></font> </div>
<div><font size="2">Take each socket out of the gauge and earth it with another
wire. Make sure your earth wire is good, can your test lamp check earths
as well as 12v?</font></div>

<div><br></div>
<div>The dash lights don’t work on my 1972 MGB. The trouble
lite will light when I test the sockets, but various new bulbs won’t.
Does this mean low voltage? I’ve grounded the test light on a bolt
and assume the dash is grounded.</div>
