I think it's time that we built a 906 specific technical FAQ-thread the way we have been building one in the 750 forum. I'm by no means a 906 expert but can troll thru the threads to find what I think might be important but it's the users of the forum that really know what's unique and needed to populate this FAQ. Please add the past threads that you think will be most useful for others.

Connecting an ELECTREX regulator/rectifier:

Electrex to original wiring
yellow -> both pink (alternator)
yellow -> red (alternator)
white -> light blue (charging warning light)
red -> red/black & orange (battery +)
green -> black (battery -)
(the brown wire of the Paso wiring loom formely going to the regulator is not used any longer)

Note: If the measured voltage between the two yellow wires from the alternator (which are pink when they get to the regulator/rectifier) is between 50-100V you should wire the reg/rect as shown on the first picture of the instructions hence connect yellow 1 from the reg/rect to one yellow(pink) wire from the alternator and yellow 2 to the other. In this case the red wire from the alternator isn`t used and can be isolated. Install like this if the first wiring instructions don`t work. (To check simply connect a voltmeter to the battery. When the engine is started and the regulator/rectifier is connected correctly the voltage will increase i.e. from 12V to ca. 14V)

Clutch piston

for the 906s with the clutch piston in the clutch cover (not the later ones that have it on the left engine side)
