Description

Alternator wiring harness for the Citroën Traction Avant 15-Six 6 cylinder engine. It was made with a connection to the 2-pin block under the voltage regulator.

Used from 1946 to 1952.

Because of the longer engine this wiring loom is a lot longer than the alternator wiring harness for the 11BL and 11BN.

100% original or with fuses

SKS supplies all dynamo booms for the Traction Avant in two options: 100% same as the original or a version with fuses. For extra safety, we recommend choosing fused.

This is a main fuse. If the engine is not running, or is idling, the voltage of the alternator is too low. The voltage regulator then disconnects the alternator from the battery. In this situation the battery is the power supplier. The main fuse is placed in the ignition switch wire on the starter motor. On the dynamo wiring harness after 1954 (without block) this fuse is placed in the dashboard harness.

At sufficient rpm the alternator will start supplying power and will take over. That is why a main fuse is placed in the wire, DYN, to the regulator. In case of a short circuit between Plus 6 V and ground, one or both fuses will melt. The Traction will then stop completely, because there is no spark anymore. Better this than a burned out wiring harness or even worse.

The DC dynamo delivers a maximum of approx. 20 A. The value of the placed fuse is 30A.

For an alternator it is better to increase the value to 40A. An alternator delivers more power and after a long start-up the alternator will charge the battery with a higher current.

Voltage regulator type

The 4 wires from the 2-pin block to the voltage regulator are deliberately made extra long. This was done because hardly any Traction drives with an original factory-supplied regulator anymore. Experience has shown that the connections of the
replacement regulators are fitted in several places: underside, side, top. All 4 wires are left a little longer, so it is always possible to connect to the top side as well. Other wires for connections on the bottom side are then admittedly too
long, but these can then be neatly tied up with a curl under the controller. SKS made a conscious decision to do this, as we want to deliver plug-and-play for the customer, and extending a wire, pinching on eyelets and insulating it with shrink tubing is not an option in that case.
