2003 260DA holding tank disconnected by previous owner, how to re connect electronically?

[Punkray]

Hi all,

I just bought a 2003 260DA with a vacuflush with holding tank. The vacuflush works fine and flushes directly out of the boat when you turn the key in the head to 'power'. The holding tank has been disconnected by one of the previous owners and I want to reconnect the holding tank. I can re-route the hoses, that's not the problem.

The waste pump had a cut wire with tape, so i reconnected that wire, but still nothing happens when i turn the key switch in the head. After using the multimeter I found out that the is no power going to the waste pump when I turn the key to the 'pump out' position. Is there a hidden fuse somewhere that I might have missed that has been taken out perhaps?

Thanks in advance for any ideas

On my boat there is a microswitch on the waste seacock - ive never used it, but my understanding is that it bypasses something.. ( a pump? ). Tried closing this seacock? ( and test flush with clean fresh water! )
