This defected (short circuited) coil is the one used for swing brake of komatsu PC300-6. It is a 28VDC 20watt, manyfactured by vickers. At komatsu it is sold as an assembly: coil + valve Is it sold alone by other manufacturer, any idea where to find an equivalent?
Without knowing the size it looks similar to a HydraForce coil, but I'm guessing
Hydraforce are different. Vickers coils are available separately. I googled "vickers 24v coil". 3rd hit https://www.google.com/url?sa=t&source=web&rct=j&url=http://www.eaton.com/ecm/groups/public/@pub/@eaton/@hyd/documents/content/pll_2140.pdf&ved=2ahUKEwiki9-jt4LgAhWOm-AKHYFYAuoQFjACegQIBRAB&usg=AOvVaw2vjIP3tQYN0CAysjfdsOxF has the whole Vickers coil info.
