I have found a new 7 cable rectifier for my V-strom and now its arrived I have discovered the plugs are different. The 3 feeds into it from the alternator should be ok however the problem is the 4 outputs. The old rectifier had black/white and black/red. Now I have red and black. Common sense tells me red positive, black earth. But before I cut old and new plugs off does anyone have any ideas or shall I bite the bullet send it back and buy an original for £200.
Any help greatly received.
