Volvo TVS for 1800E and 1800ES.

Warren has been doing some investigation into the Models of Bosch TVS used on Volvo 1800 D-Jetronic engines.

The general view has been that Bosch Part # 0 280 120 012 and 0 280 120 026 were used on MY70 and possibly MY71 1800 cars, after which the Bosch Part # 0 280 120 039 was used.

After some investigation and research, gathering responses from 1800E and ES owners and using the 1800 Register at volvo1800pictures.com and Volvo Service Bulletins, it has become clear that only the 012 and 026 TVS were factory fitted. The 039 TVS was not available until November 1973, after the last ES car was manufactured. It was offered as an Upgrade to the earlier model TVS, to be fitted if a replacement was required and is seen fitted on a many of the surviving cars. A segment of the relevant Volvo Service Bulletin is attached.

The 012 and 026 style TVS is now included in the main Wiring Diagram, with the 039 TVS as an update in a dashed line option box.
