I give maintenance to a Gyroscan 5NT and this show low pressure inside the magneto. It show 20 mbar all time I try to make rise it using the MAIN HEATER but don´t function. The pressure gauge work perfect.
Please check that the Helium fill port sealing nut is tight and that there is an o-ring there as well.
You should also check that the burst disc is not leaking, also check the sealing rings and o-rings on the ramp lead ports. In other words you're looking for a leak.

Hi
try to check the burst disk.
if it is OK and helium consumption is not to much then somewhere is leaking try to find it with foam.
