minivin Posted September 16, 2005 Share Posted September 16, 2005 Anyone know which terminals are input and which are output? Now if I was designing a circuit with one set blade, and the other socket, I would have the input as the blades (pins) and the outputs Sockets, that way if the input wire socket came off it could not short due to the insulation over the contact. Without breaking out a powersupply, multimeter and possibly blowing the ickle device up by routing current through it backwards, would anyone like to agree with my theory Quote Link to comment Share on other sites More sharing options...
rtbarton Posted September 16, 2005 Share Posted September 16, 2005 I'd like to agree. I think the terminals are labelled "I" and "B" or something. "I" for instruments? Quote Link to comment Share on other sites More sharing options...
minivin Posted September 16, 2005 Author Share Posted September 16, 2005 just had a look over the module, it's a Britparts bit but unfortunately no markings Quote Link to comment Share on other sites More sharing options...
Outrage Posted September 17, 2005 Share Posted September 17, 2005 From your description, i think i've wired mine up in reverse it works fine though. My input terminals are the female connections that accept the male (flat) spade crimps. The outputs use the others. No particular reason for wiring it up this way other, although using the normal plug and socket phylosophy probably would make sense.

minivin Posted September 17, 2005 Author Share Posted September 17, 2005 good innit it also sorta makes sense as the unit sockets are on the same side as the fuel and water temp. guages, but when did Lucas ever use sense Quote Link to comment Share on other sites More sharing options...
02GF74 Posted September 20, 2005 Share Posted September 20, 2005 I might be able to answer this - have you figured it out or still pondereing? Quote Link to comment Share on other sites More sharing options...
minivin Posted September 20, 2005 Author Share Posted September 20, 2005 still pondering Quote Link to comment Share on other sites More sharing options...
02GF74 Posted September 20, 2005 Share Posted September 20, 2005 Will take a look ... but remember I did say "might" In any case it is a 50/50 chance of getting it right/wrong. The earth is done via the regulator body to the speedo - I see you've painted your's black so ensure there is a good metal-metal contact.

minivin Posted September 20, 2005 Author Share Posted September 20, 2005 it's all right on that account, rivetted it on as couldn't be fussed to use a self tapper, and then painted over the top so there's a good connection through the rivet Quote Link to comment Share on other sites More sharing options...
02GF74 Posted September 21, 2005 Share Posted September 21, 2005 this is what I've managed to glean from manuals. There are two pairs of spade connectors: One pair labelled I has light green wire going to it (output). Other pair labelled B has green wire (input) to it. Manuals do not give enough detail as to which are the male of female spades but I would go along with your logic that the input would be the male spade, the incoming wire being an insulated female. B) My stabiliser is behind the dash so couldn't look at it. This may be of use - looks very similar. I don't think you will damage it if you connect the wire the wrong way round, in any case your ole input wire should have the appropriate connector right?

minivin Posted September 21, 2005 Author Share Posted September 21, 2005 shweet, cheers for that, as I have made a new loom since I've also converted from 24V to 12V at the same time, my 24V loom did not have the regulator wiring B) so I had no comparison Job Jobbed, better go finish the rest of the wiring and see if the beast will fire-up Quote Link to comment Share on other sites More sharing options...
