Can anyone assist with the above item, just purchased for a tenner at the Portsmouth Boat Jumble.
TP has a 4 pin Bulgin connector with 4 wires connected. Can anyone advise as to what these wires do? In particular which wires are the 12V +ve and -ve?
Wire colurs are Blue, Red, Yellow and Green.
The PDF from the Simrad website suggests that only a 2 pin plug is fitted, with Brown and Blue being +ve and -ve connections respectively. As mine has the 4 pin plug, I'm stumped!
The PDF also suggests a JB5000 connection box, does this have the 12V supply fitted to it?
If anyone has any details on this Tillerpilot, I'd be grateful for info, or indeed, if you have any other parts which interface with it that you no longer require and wish to sell, please let me know. Must be cheap as obviously I can't test the unit until connected up, so don't want to spend too much on what could be a duff unit!!
Thanks.
 
I've got a Navico TP30, a bit more recent than yours I believe. The manual is on the boat, but I'm virtually certain red & blue are +ve and -ve. ( but no guarantee ! ) IIRC, Navico had their own data bus, I forget the name, yellow and green might be for that. My TP has 6 pins, the extra 2 being NMEA, again I can't remember the colours.
Edit, just found some wiring colours for TP30:- red & black +ve & -ve. Green & white are for Navico "Corus" data, eg an external compass for steel hulls, or I think, a windvane could be connected here, also 2 wires with no colour specified for NMEA. Not quite as I remembered but it might help.

Just taken unit apart and Red/Blue are the +ve and -ve DC supply.
The Green/Yellow returns back to the multiplug connector to the remote control (which I also have) so as you say, probably NMEA/Windvane/Compass connections.
A wiring diagram would be useful if anyone has one?
