Sir Nibble Posted August 30, 2017 Report Share Posted August 30, 2017 OK, that proves that it's the purple that's on terminal 30. Move the white back to that centre terminal then swap the green/yellow and purple and it should work correctly. Well done. Link to comment Share on other sites More sharing options...

Sir Nibble Posted August 30, 2017 Report Share Posted August 30, 2017 Odd. Still definitely the relay tho'. Does it go click when you switch on? Tomorrow is soon enough. Link to comment Share on other sites More sharing options...
Cheshire cat Posted August 30, 2017 Report Share Posted August 30, 2017 Fascinating thread. I understand how Sir Nibble has diagnosed a faulty relay but it feels like I am watching keyhole surgery. Link to comment Share on other sites More sharing options...
bigcol Posted August 31, 2017 Author Report Share Posted August 31, 2017 Okay any ideas. lets go to the beginning 1)alternator Ist left light didn't come on with ignition on,but comes on when engine running 2)we thought it was the domestic alternator light at first we had this tested at alto electricians confirm NO FAULT domestic alternator 3) forum member pointed out we had diagnosed the wrong alternator, engine alternator far left, domestic alternator 2nd from left.this works as it should 4) so ist alternator light is engine is the faulty one 5) we haven't tested this alternator 6) we haven't tested the engine battery 7) we've tested with forum members patience the electrics behind the panel because before I thought I tidy up the cables and wires. while doing that I broke the BT, but with the forums help we fixed that, 8) so still left with a engine battery charging warning light faulty. 9) will have to wait till I get back and have the engine alternator taken off and checked 10) will have to have the engine battery tested when I get back be nice to know what is wrong, other wise it means getting engineer in to remove replace or repair, or at worse nothing is wrong with them. any faults folks?fuse you all or like me I've managed to cause you mental exhaustion, and confuse you all col 17 hours ago, Cheshire cat said: Fascinating thread.

It's clearly a relay fault but my attempt to temporarily fix it by running ign + from 30 to 87a is giving apparently conflicting results. A fresh pair of clued up eyes may spot something I missed.

I follow what you are trying to achieve, but can't find a Beta diagram that matches the colour coding. Would a shorting link between 30 and 87 (without disturbing any of the existing wiring, and with the ignition off) cause the domestic alternator lamp to illuminate? Which is of course the same as moving the white wires from 87 to 87a. I also notice that one of the black wires appears to be held in by the spade connector; and that there appears to be two wires (brown/yellow?) on the other side of the lamp. Bigcol, can we have a few more pictures please. One showing the whole of the back of the panel and one around the ignition switch. I see that you replied whilst I was typing this.

Believe it or not there are two terminal layouts for this size of relay; the other type has terminals 30 and 86 transposed. Link to comment Share on other sites More sharing options...

The one you have bought is different to the one shown on most Beta diagrams. Swop them over by reference to the terminal numbers and not their positions (although they may be the same if the old relay is not the original) Edited August 31, 2017 by Eeyore Link to comment Share on other sites More sharing options...

Eeyore Posted August 31, 2017 Report Share Posted August 31, 2017 (edited) Just pulled these from the Durite catalogue to show the difference. Note that the electrical drawing is the same for both.

bigcol Posted September 6, 2017 Author Report Share Posted September 6, 2017 Problems same or different no we haven't got our post rebthe relay, tomorrow fingers crossed i came from Marsworth to pitstone today noticed on arriving the domestics batterys on the gauge was well down to 40 to 50 on the bar graff, also battery voltage down to 12.1 so I've ran engine to see if the volts go up, but if anything they went down a little. Domestics tonight i put volt Mtr on ENGINE battery with engine running 14 volts engine stopped 12.7 volts DOSMETIC batterys 12.4 volts with engine running the same with engine off i put voltmtr lead on terminals on alternator and still reads 12.4 volts i had the alternator taken off for repair, but nothing was found wrong with it!! so was put back on. Something defo a miss, makes you think if the alternator light is the wrong was round?? col Link to comment Share on other sites More sharing options...
bigcol Posted September 6, 2017 Author Report Share Posted September 6, 2017 I'm going to do continuity tests to make sure the alternator light hasn't been changed around from domestics and engine. and will let peeps know when I have relay in my hands col Link to comment Share on other sites More sharing options...
Tony Brooks Posted September 7, 2017 Report Share Posted September 7, 2017 The easiest way to check that is to turn the ignition on and then take the warning lamp wire of the alternator. The lamp that goes oput is for that alternator. I know you only have one lamp working but just find whichever alternator is associated with that lamp.
