Fuse Blown

[Michael Barbare]

Roland vp 540
Continually blows Fuse F1 on main board

Install new fuse turn main power on fuse is still good

Turn secondary power switch on and fuse blows immediately

I disconnected all 4 print heads install new fuse turn power on at rear fuse is good turn power on front blows fuse

I install new fuse disconnect carriage board turn power on at rear fuse good turn power on at front fuse blows

Anywhere else I should look before I buy a new main board

Are you sure you are using the proper rated fuse? It should be a 1.6 amp, 125 volt, Quick Blow fuse.

Check the long trailing cables that go from the slider to the main board and don't forget to check the terminals the cables plug into on all of the connections. Damage can occur to the terminals when inserting and removing the cables.
