- How to check out the R/R
If you have the Kawasaki Service Manual, you will find R/R checkout on page 15-18. If you don't I will list what is there for you. Quoted from the manual as much as possible: Regulator/Rectifier Inspection Remove the left side cover. Pull out the connector. Be sure to set the hand tester to the 100 ohm range and zero the meter(Not necessary on a digital meter) Check the resistance between the regulator/rectifier terminals as follows(there is a chart and picture in the manual which I cannot reproduce right now but I will try to put it in words for you)
A1 A2 A3 All Alternator Terminals --- --- --- Connector with pins facing you and notch at bottom --- --- ---
G M B G = Ground M = Monitor B = Battery --|__|-- (Hope that came across right)
Measure B to M - should read infinity
Measure B to G - should read infinity
Measure B to A1, A2, A3 - should read infinity
Measure M to B - should read > 10K ohm Measure
M to G - should read > 10K ohm
Measure M to A1, A2, A3 - should read > 10K ohm
Measure G to B - should read between 0.4 to 2K ohm
Measure G to M - should read between 1 to 5K ohm
Measure G to A1, A2, A3 - should read 0.2 to 0.6K ohm(200 to 600 ohm)
Measure A1, A2, A3 to B - should read 0.2 to 0.6K ohm(200 to 600 ohm)
Measure A1, A2, A3 to M - should read infinity
Measure A1, A2, A3 to G - should read infinity
If there is more resistance than the specified value, the unit has an open lead and must be replaced. Much less than this resistance means the unit is shorted, and must be replaced. Hope this helps someone out there. Dan Morgan
