I snipped one of the EOS wires off - and it made no difference. When i though about this approach, i think this was the wrong way as the EOS should be normally closed, so if i snipped a lead off, the coil should only power at hold strength?

So then i jumpered the the two coil lugs where the EOS contacts were wired to, and it works.

Thanks Daniel, champion. I'll clean the contacts of the EOS, although as its not my machine, may be more reliable getting a new EOS
