Hi, We are having trouble with our AquaTrol and ordered a new transformer GLX-XFMR.

When reading the troubleshooting guide from Hayward (and on this forum as well), we noted that the transformer should read 2.0-2.9 Ohms. The new one we received is testing 4.0 on grey and violet; and varies from 3.8 to 4.2 on blue and white! Is it safe to assume that the ''new'' transformer we received in malfunctioning?

BTW, reading more and zooming at the limiting varistor we now see it needs to be replaced. Just hoping we can return the transformer and ask for full refund :)
