Just a brief update on all things electrical !!



The wiring loom has turned out to be considerably more time consuming than I imagined......I 've probably spent the best part of 60hours endeavouring to remove unwanted wiring and checking to make sure nothing has been left out......unfortunately ...as is nearly always the case despite constant checking I managed to remove the oil pressure warning light wire and the alternator warning wire, I would point out that the wiring loom was a high series and had considerable additional equipment wiring that you don't need like the lamp warning module along with all its wiring and all I can say is check, check and check again!!  The dash wiring still looks pretty jumbled at the moment as I have not managed to fit it to the warning lights or switches as the dash console is not complete. But the worst is over and everything is labeled ready. The real moment of truth comes when after several days/weeks of removing wires you come to restart the engine !! Mine didn't start !! and after much soul searching and in the knowledge that it worked previous to me tampering with the loom I swiftly came to the conclusion that I must have removed a wire from the ECU........or more seriously had damaged the electronics in some way as I was getting no output any where in the high/low tension circuits.  I decided to go through all the wiring and associated components  in order to confirm my fears. The Haynes manual, although lacking in some areas has good wiring diagrams which I used to the full. After checking the wiring, made more difficult because most of it is neatly bound together within the loom, I found all to be well......scratching my head I made some basic checks and finally discovered the coil had failed!! As this was a new coil I was suitably unimpressed as you can imagine!! I fitted the original coil from the donor and she fired into life much to my delight!

I have since added wiring for the alarm system which uses microwave technology to put two zones around the car one external and one internal, I decided on this type as it is useable with the hood down and will alarm if anybody leans in. Unlike ultrasonic it is not effected by shifts in air or temperature and will not false trigger. I decided after hearing of the problems associated with fitting the door locks that there was no point in fitting them!! I have used the remote output from the alarm system to drive the solonoids and this works extremely well. For all those that are asking what happens when the battery fails (both remote control and car battery) I have a solution.
The situation with the dash has been somewhat longwinded. The choice has always been go proffesional or DIY. Normally I would spare no cost !! and get the proffesionals in...  but things being as they are (tight!!) I decided to do it myself after taking the necessary advice from anybody that was willing to give me information, this included my daughter who recently brought home her latest attempts at carpentry from school!! Only time will tell if this is the cheaper option or not. I am quite sure I can match the finish by taking my time and following the carefull instructions of my professional suppliers who are only to willing to help. 
You will see various stages of my dash build in the photo's on this page...as I go to press I have changed the layout so although the principle is the same the layout isn't!!

My first problem was in making an accurate blank that fitted the interior moulding allowing space for the trimming cloth... this proved much more difficult than initially anticipated due to the curvature of the moulding and after 3 different attempts a blank was made that I was happy with. I decided to use 8mm MDF (recommended) although I had initial attempts in both 6mm amd 10mm (Cost's are rising!!)

<>The next stage was to agree on the switch and lamp layout on the dash, I already new the format I wanted for the dials. I cut several pieces of paper of the correct dimensions and merrily set them up as to were they looked best.......I eventually became more scientific in my approach and measured distances etc so as to have a more symetrical design! Once I had the basic design sorted I went about completing the wiring for the switches. I had decided to use pull switches so had to ensure they were within the exempt area for SVA. I had also decided to use LED's instead of lamps as these came in a better range of styles and were considerably smaller.
I soon abandoned the LED idea after spending an evening (or three) trying to improve on the fluctuation in brightness brought about by the different colours having different current requirements. I moved to 12 volt lamps.......why make things difficult!!
As can be seen the dash blank had been completed, the most difficult part being the cut out for the door and more importantly ensuring the door fitted. I could have purchased a preveneered blank but I was concerned that one slip with the Jigsaw and the blank would be ruined ....especially as you have to cut the door from the blank which needs to be perfect. Much easier to make your blank and door which can be seperate pieces and then veneer them......I think.
As stated earlier I have changed the lamps and so have had to make yet another blank (more cost) however this is now complete and I shall be veneering it shortly!! I'm sure your wondering if it is any cheaper?  Well it is certainly time consuming as I expect the actual veneering process and laquering to take at least 15 evenings given the drying time between coats etc. however I do believe the cost will be significantly below purchasing direct....costs to date are MDF for blanks( you can use ply) £18 (get it right first time and this will be less!), Hole cutter for dials £7 at show (..normally about £15), Complete parts kit for veneering including, veneer (Burr Walnut), laquer, wet&dry, Finishing compounds, Polishing wax, walnut paint etc. £48. So in all excluding the labour the cost will be approx £72 to complete both the main dash and the radio dash with just a little left to cover my electric window switch plinth........provided I get it right!! check out gallery 5 later in the year to see how I got on!!.
