A good start to the week, I completed the flasher wiring and that means the cab wiring is done now, except for the lighting panel connections.  To progress that, I sanded and painted the lighting panel wooden base.   I’ll leave refurbishing the actual switch box now to be a winter job.    I next turned my attention back to the front wing,  fitting an edging strip to the rear sharp edge, then fitted the beading and piping to the front wheelarch opening in preparation for fitting the new front mudwing.  Fitting the mudwing required some wood packing pieces to be added to the wheel arch, not surprise as the original incorrect wing also required packing, and was a slow job, getting it lined up then jacking and packing into position.  However, it fits very well now, much better than I expected.  Last job of the week was to apply filler to the curved front face of the wing, to conceal the welds, and start rubbing it down.

Started the week by moving the starter motor positive cable over to the terminal next to the battery positive, which cured the volt drop at the cable terminal.  The starter motor now engages but there is insufficient power in the batteries to turn the engine over, so replacements will be ordered next month.  I then drilled the connection box for the indicators and  ran the five-core cable up the cab door pillar to the junction box above the cab door.  The next task was to bind together with heat shrink the three large cables that go up the rearward cab door pillar, two being power cables to the lighting panel and the other being a three-conductor multicore to the indicator junction box.  I fixed them to the bulkhead alongside the cab door with hand made brass straps.   Adding the two-core wire for the flasher unit meant I was able to test the indicator circuit, with success.   A this point I decided the indicator switch was the wrong way round compared with the MW, so that needs corrected that.  Final jobs of the week were to remove the interior lights switch panel from its base and temporary reattach it to the cab bulkhead so I could lay in the wiring to the flasher unit and set the route for the multicore from the indicator junction box back to the main control box.  This required a minor alteration to the switch box base board to accommodate the cable.  I also noted an oil and paper 0.5uF capacitor on the base, not certain of it’s purpose but I will replace it with a modern one as it is leaking.  It appears to be connected across the 24v supply on the switch box.  I also applied a third, darker coat of undercoat to the new front wing.

Another relatively slow start to the week.  Painted another coat of silver on the underside of the new O/S wing and around the aperture for the new battery trays.   I also plugged all the screw holes for mounting the trays and covers.   I should have done the rear two as well but forgot about them!  Made a start on the control box, blowing as much dust off as possible then removed the top panel for cleaning and painting or polishing.  I took out all of the screws,and with a bit of gentle persuasion it came off, having corroded slightly to the steel switch plate.  I also primed then painted the side panel for the box with engine black, two coats, and put it to one side to cure properly.  I next thoroughly cleaned the top panel and removed the blanking plates and plug, and the surround for the starter switch, (theses being pressed in) and painted it with hammerite.  I have ordered an ammeter, as there appears to be provision for one and space on the large cover for it.  I have also ordered a voltmeter for the top panel.  I stripped the paint and rust from the large cover for the control box and spent some time adjusting it so it will fit properly.  A coat of “number one rust beater” primer was next, followed by a coat of green Hammerite on the inside surface.  I then had to make two sliders to replace the missing ones for the control box switches, the originals were 0.8mm nickel silver, so after a failed attempt in aluminium I used 0.75mm brass which worked well.  Not a bad week’s progress, considering I lost two days work for other things.
