As standard, units are supplied fitted with cooling fan and 63mm diameter pulley suitable for 10mm wide ('Z' section) belt.If a different pulley is required, then please enquire. Alternatively, use your original pulley on the new unit as the shaft sizes are the same.

Electrical connection to the vehicle is easy and straight forward using the original dynamo control box as a junction box. Fitting instructions are given in the downloads section below (one for negative earth installations, the other for positive earth). Alternatively, the original voltage control box can be removed and replaced with a fused dummy control box, which can be used as a suitable junction box to easily connect the Dynator to the vehicles wiring.
