dave.vitesse Posted August 12, 2018 Report Share Posted August 12, 2018 Looking at the picture Pete, and I may be wrong but they look like the dreaded electronic type that have no short circuit protection. Dave Link to comment Share on other sites More sharing options...
dougbgt6 Posted August 12, 2018 Report Share Posted August 12, 2018 Dave, That seems unlikely if Pete rescued them from a skip in 1923. Doug 1 Link to comment Share on other sites More sharing options...

68vitesse Posted August 12, 2018 Report Share Posted August 12, 2018 Back of Vitesse speedometer, right terminal, red spot, marked B left marked I. Regards Paul Link to comment Share on other sites More sharing options...
Guest Posted August 13, 2018 Report Share Posted August 13, 2018 I note all male terminals on this unit, makes you think if there was any rationale behind what type connectors were fitted or perhaps just lucky dip out of the voltage stabiliser bucket ??

Pete Lewis Posted August 13, 2018 Report Share Posted August 13, 2018 Until this and the odd one in my parts bin!! All have been inhibited its important they are wired up right way round, Doesnt matter if its pos or neg earth as far as I remember they are load direction dependant not polartity Obivoisly has to match the designers harness but the male/ female version means they are always correct.and line operators didnt have a choice to get the harness back to front , twit proofed.

Guest Posted August 13, 2018 Report Share Posted August 13, 2018 Pete, Certainly makes sense. The above was obviously the advanced version ? !! Regards. Richard. Link to comment Share on other sites More sharing options...
dougbgt6 Posted August 13, 2018 Report Share Posted August 13, 2018 Interesting that this one is screwed to the back of the gauge, mine is on the mounting pillar, saves a screw I suppose. But, why is it here?!! There are so many other easily accessible earthed mounting points. Logic says put it on the back of the fuel or temperature gauge, but no we'll put it here, in the most difficult inaccessible place we can find. Protectionist engineering, a common attitude when I was an apprentice, "Don't make it too easy for them! We don't want everybody to be able to do it!" End of rant. db Link to comment Share on other sites More sharing options...
68vitesse Posted August 13, 2018 Report Share Posted August 13, 2018 Recently changed or cleaned the bezel on the guages in my Vitesse, the most difficult to remove was the fuel guage followed by the speedo. But the cables to the stabiliser where long enough to disconnect and reconnect before putting the guage in the dash. The bean counters could not have known about this blatant waste of money.

dave.vitesse Posted August 13, 2018 Report Share Posted August 13, 2018 The" B" marking near the terminal indicates the battery connection, Green lead. Some had "I" on the other terminal to indicate Instruments, Light Green/Green lead. They must be connected that way round to work correctly. The logic would have been to make the unit with a male on and a female on the other connector so you couldn't get them the wrong way round. But! I agree with Paul, where a unit was mounted had a lot to do with keeping the costs down i.e. the shortest routed for the wires. Costing Engineers.

68vitesse Posted August 13, 2018 Report Share Posted August 13, 2018 Marked my leads and unit with a felt tip before disconnecting, red for port, left, green for starboard, right. Regards Paul Link to comment Share on other sites More sharing options...
Chris A Posted August 13, 2018 Author Report Share Posted August 13, 2018 The stabilizer on mine is mounted on the back of the speedo. I had the same reaction why there? Difficult to get at & the gauges it serves are on the other dial, I guess lack of space on the other dial. From memory, the existing unit has 2 of each connector, I'll know for sure when I replace it later this week. Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 13, 2018 Report Share Posted August 13, 2018 the mount on the speedo is purely convenient and makes a good heat sink as the unit does get quite warm cant say where mini fit the non bracketed version on the speedo was a common Smiths design placement Pete Link to comment Share on other sites More sharing options...
Badwolf Posted August 13, 2018 Report Share Posted August 13, 2018 I have one which has a male 'B' connector and female 'I' connector, whch I thought they all had as this is the correct wiring notation for modern power in/power out devices, obviously to prevent shorting to earth.

Anglefire Posted August 13, 2018 Report Share Posted August 13, 2018 Connecting the supply to A or B doesn't matter - its just a bimetalic strip - when its cold A is connected to B and that causes a current flow which heats the strip - gets hot enough and the contact opens, the current stops so it cools down. The electric doesn't care which way it goes! Link to comment Share on other sites More sharing options...
Badwolf Posted August 13, 2018 Report Share Posted August 13, 2018 Doug. Sorry, breaking this tablet in for Pete, using his new spellcheck for his 'other forum'. Now corrected. Link to comment Share on other sites More sharing options...
68vitesse Posted August 13, 2018 Report Share Posted August 13, 2018 Not an ectrician but if connections are the wrong way round the heating coil would have a permanent supply so there would be no supply to the instruments. The diagram would appear to be with the bimetal strip heated. Or am I confused. Regards Paul Link to comment Share on other sites More sharing options...
dave.vitesse Posted August 13, 2018 Report Share Posted August 13, 2018 As the 12 volts is being applied to the heating element all the time this would result in no 12 volts at B as there is no switching taking place. Plus the heating element may burn out. Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 13, 2018 Report Share Posted August 13, 2018 hence why inhibited terminals stop all this conversation just tried 46 attempts at doing my driver licences on line for a 70+ what a blasted frustrating waste of time that was, and when it tells you to phone in they cut you off and say do it on line and goodbye were busy Pah Humbug every log in and password i had for gov gateway is defunct, and im using the wrong fore name really so ive applied as a traveller Pete 1 Link to comment Share on other sites More sharing options...
68vitesse Posted August 13, 2018 Report Share Posted August 13, 2018 Had to do mine earlier this year, if you want to keep the C1 D1 classification if you have it, depends when you past your test, you will need a Doctor to sign you of as fit. I wasn't bothered as can not remember last time I drove a mini bus or a vehicle up to 7.5 tonne, have heard of people losing motor bike qualification. Take copy of back of old licence as proof of entitlement. New licence has to be renewed every three years. Take it this is thread drift.

dougbgt6 Posted August 13, 2018 Report Share Posted August 13, 2018 I applied for my "ancients" license. "Can you see?" "Yes" "OK, granted" It arrived after a month, followed 3 days later by a second. I shall keep one for speeding points and the other for best.

Pete Lewis Posted August 13, 2018 Report Share Posted August 13, 2018 you have to cut the old up and send it back to dvla now or you get a spell in the tower you have to confirm youve sent it but i wont till the new one arrives thread drift , well yes i was bored with stabiliser's Ha !
