My never ending 89 Cali 3 project is nearing completion.. well hopefully, but the wiring of the rectifier is confusing me. The rectifier has 4 wires going into to it.They are labelled from left to right, the first two have a wave sign, the third a '+' and 'L.E' and the fourth with an open switch sign. Though the '+' sign could be to id another pin which is missing on my rectifier. There are three wires from the alternator, a grey wire and two yellows, the latter of which I think both go to the rectifier (the first two id with a wave sign).
The grey wire from the alternator I'm told goes directly to the +ve side of the battery, as its already rectified at the alternator. Which leaves the two connections on the rectifier, the third 'L.E' and the fourth (open switch sign). My best guess is the fourth connection is to operated a charging idiot light, but the third with the Id 'LE' is a mystery. My best guess is that it too goes to the +ve side of the battery, so the rectifier can tell when the battery is being over charged and so limit to charge from the alternator. Can anyone clarify what wires go to each of the four terminals of the Saprisa rectifier ?? Thanks, Lee

The yellow wires are the AC output, but it is a two phase alternator, ie. two stator coils with the centre being connected to the battery positive. All the rectification is done on the negative side.
The other two, LE is the charge warning light, the other is a sensing feed from the battery positive, but switched via the ignition. It is also imperative that the case is earthed extremely well as that is the earth return of the charging circuit, usually best to run an extra wire from the battery negative to the rectifier case.
