In the 1970’s French company S.E.V. Marchal brought out a new type of ignition with the traditional points built into a cassette. This made removal and fitting must faster and easier, but you could no longer set the points gap with a feeler gauge. A dwell meter must be used instead. Most garages would have had a dwell meter for accurate setting of standard points so this would not have been a problem, however for the DIY owner used to setting points with a feeler gauge (or “eyecrometer”) it posed a problem. From the enquiries we’ve getting, it seems this still poses a problem, even for professional garages. Many garages now do not even have staff who know how a traditional points based ignition system works, let alone have equipment for checking and setting the system. And it’s not really surprising seeing as most vehicle manufacturers had changed over to electronic ignition systems by the early 1980’s.
Just as modern vehicle technology has rendered most DIY vehicle maintenance obsolete or impossible on today’s cars, the modern garage can no longer properly cater for vehicles made before 1980. This is where specialist garages like us are invaluable. We know how your car works and how to repair / adjust and service it using the correct parts and grades of oil. We can also help DIY owners and modern garages with information about maintaining the older vehicle, the information sheet below on how to set cassette points being case in point, if you’ll pardon the pun.

We’ve had a few people asking us about the instrument panel connections on their post October 1969 Citroen DS or Citroen ID, so I’ve written this post to help you find the information easier.
A = Instrumentation illumination
B = + ignition feed for warning lamps
C = Fuel gauge (to tank unit)
D = – Earth
E = Tachometer (rev counter)
F = Temperature gauge (if fitted), to sensor on engine.
A = Main beam warning lamp (blue)
B = Dipped beam warning lamp (green)
C = Rear screen heater warning lamp
D = Hydraulic pressure warning lamp
E = Alternator (charging) warning lamp
F = Empty
A = Left indicator warning lamp
B = Engine oil pressure warning lamp
C = Brake pad wear warning lamp
D = Right indicator warning lamp
E = Hazard warning light (bottom middle red light)
F = Coolant temperature warning lamp
Items such as coolant temperature gauge and hazard lights are not fitted to all models, but the circuits already exist in the instrument panel so it is just a matter of connecting to the appropriate terminal should you wish to add these features to a car without.
