Star delta starter / motor problem.
Starter starts runs as should on bench with no motor connected. Getting 230v to e on all 6 uvw 1s and uvw2. 415 u1 to v2 etc etc. But nothing 1 to 2s. As expected.
When motor connected up. (Single speed) it takes 3a in start on all . Drops into run fine but is taking 38a on all.
After 5 seconds it trips breaker.


Any ideas were to start. As both out of stores as spares and checking they work but now stumped
 
could be a few things, im no expert on motorwindings but when they lose balance tends to be when things go pete tong, was there a reason it was stored away no longer used or was it working last time it was tested?
