Magneti Marelli 95-98 Land Rover/Range Rover
The purpose of this amendment is to allow the MOBI-ARC PWM regulator to control builder. Read through these pages before undertaking change. People are not mechanically inclined can choose to get local Builder re-builder to facilitate this change.
In its original configuration using this generator diodes in rectifier plate known as the "avalanche" diodes. Avalanche diodes are fine for charging, but they are incompatible for welding due to their limited breakdown voltage rating. In order to use the manufacturer of the generator the MM, shall be installed a rectifier plate with standard diodes. We have manufactured bolt in rectifier plates with standard diodes. Rectifier plates look identical but electrically different.
Remove rectangular capacitor. Loosen the nuts as necessary to remove the plastic cover from the rear of the generator. Plastic cover can get crazy so handle with care. When the rear plastic cover is removed, it should look like this:
With a high-heat soldiers iron, unsolder stator wires from the original avalanche diode rectifier as identified by arrows green above.
Stator wires become detached from the plate rectifier that remove nuts and screws. With hardware removed, original regulator and avalanche rectifier is removed from the generator. With this constraint, Blister pack heat transfer grease (54013LN), apply to replacement rectifier (IXR543).
Nylon shoulder washer 12SWS044 and # 10 Nylon flat washer should already be mounted on the regulator: replace new non-avalanche rectifier and regulator of the dummy. Restore hardware and be careful not to pinch any cables.
Make sure nylon shoulder washer/nylon washer sandwich is installed and proper isolation: adding shrink tube to the blue thread, as detailed below. If you decide to reinstall the original regulator, this wire as not cut it. Isolate it and tuck it away from moving parts.
