Just bench tested the Valve Block - NRV's & Pressure switch leaking. Several solenoid seals kinked but seem ok, but could have slow leak. Ordered black nitrile seal kit from X8R, which should be here in a couple of days. Replaced NRV-1 seal and test tank has held 100PSI for the last hour which is good.
3 x Miessler compressors all different behaviour.
Where did you buy these ?
- The 1st one that blew the 30A fuse runs with good air pressure, but is drawing 35-40A when running ? Not sure if this is piston alignment or bad rotor windings?
- The 2nd one we fitted to the car is drawing 10-12A as expected with reasonable air pressure (but not as much as no.1 ?)
- The 3rd one is not running at all. Need to check brushes, etc.
Standard P38 compressor refurb kits will be no use for these pumps, as they have a larger diameter piston & modified cylinder ?
