:dude:hi guys, i am waiting for a voltage stabilizer from ebay,. while waiting i started reading what items are protected by the fuses, i see that fuse 3/4 protect both fuel and temp gauges and rear brake lights and flashers, so i thought i try and see if they work , well they don,t. so i check the fuse both outside and inside, thats ok.!! my question is -if i change the stabilizer will the rest work as well?????. or is it something else????. help please i justwant to use the bloody car. paul;

Paul, the stabiliser only affects the gauges. If the other items are not working you have apparently lost the supply on that circuit for some reason. Get yourself a 12 volt test buzzer, lamp, or voltmeter and check there is a supply at both fuse terminals; you probably have a fault there (dirty or loose contacts etc).

:dude:hi vmad, i have checked both ends of fuse, and inside the car at the back of the fuse box thats ok, i want to know whats beween that and the items that don,t work ??, i am not too great on electrics . paul

As a starting point I would do straightforward stuff like a quick and easy check for the brake lights. To get access to the brake pedal switch just look under neath the dash and to remove the switch takes seconds. You can then check for 12V on the input side of the switch and also on the output side when the switch is activated. To test the rest of the stop lamp circuit take a 12v feed to the output side of the switch and your stop lights should light up.

If there is no power at the 12v input side then you need to trace the wire back to the fuse board which means removing the dash to get access to the terminal blocks.

:dude:hi guys , i may be wrong but looking at the wiring diagram. i notice that a green coloured wire goes to all the items that don,t work, to the 10v stabilizer , so it could be that they will work after i replace the stabilizer. Am i right ????. ps its a 1974 r/h car. paul

:dude:hi nigel, our repys crossed, yes i will do that check tomorrow thanks, i come to expect these problems on old cars. paul

As you say fuse 3/4 protects those items, but also the reverse lights, rev counter and seat belt warning lamp. These are all fed by the (dark) green wire circuit. If they are all out, it must be a broken connection somewhere from the fuse onwards. If the supply is getting to the spade terminal of the fuse box, then you may have a bad spade connection on the green wire (assuming it is a green wire!) or the wire is connected to the wrong terminal?

If only some of the green circuit is out, then check supply/wiring at those items.

The voltage stabilizer only powers the temp and fuel gauges. The green feed wire to the voltage stabilizer is also the same feed that powers the other items so it sound to me like the problem is in the supply from the fuse board so I would trace and check any connections from the board.

From what you are now saying I don't think that the voltage stabilizer is the problem so changing this will not make any difference.

Also check your windscreen washer as this is fed by the same circuit.

:dude:hi guys, i use the seat belt light as a low header tank light, the reverse lights won,t work as the gear box is faulty, so i can,t check these two. but the screen washer works !!!. so if one works it can not be the stabilizer . paul -----------ps- i have just looked at the wiring diagram and notice that the washer is not on the same line as the others. so do not usethe stabilizer . paul
