Just making sure this wasn't a kit?
If you did buy it then i have found them to be very touchy, like if you don't wire it properly the first time then it breaks.
Cars are very different and their tacho lines also vary from car to car, if you used a digital multimeter to read 7 volts then that is not correct, if you rev the car up you may find the voltage will increase, this is due to the signal on the -ve side not being DC and thus an "average" is detected. if it was me i would knock up a square wave signal generator to test it but failing that, i would maybe try it on someone else's car if possible.
But as you said the manual is fairly simplistic and thus it is likely that the gauge may be faulty.
