I have just finnished building the LA502T Compressor.
And I am trying to set it up.
But I dont understand
point 3 Section 'High voltage check' and 'Heater voltage check'
High Voltage check:
It says I should check the voltage Between V- an B+ pin on U5
(which is a TL431 chip).
the Setup paper say it will start at 30V and rise up to about +225V.
But I measure just 2,48V?
And in section
Heater voltage check
it says I shuld meassuer between H- and H+ on U5 (same TL431) ... it should go from 7 Volt up to 12 Volt.
I assume some thing is very strange here?
