Member Contributer RolandHTG Posted August 2, 2007 Member Contributer Share Posted August 2, 2007 99 with 87,000. Updated R/R, wiring harness replaced May 06, stator replaced March 07. Three year old Westco battery. All was fine until 6 weeks ago when charging voltage (on board meter) dropped from about 13.8 to about 12.8 at 5000 RPM. Voltage at idle has dropped from about 14.0 to 13.5. No adverse symptoms yet, battery is remaining charged except when the fan comes on. I have been using the Electrosport fault finding chart http://www.electrosport.com/electrosport_fault_finding.html I have done the connection voltage checks and the stator checks and all seem good. The next check is the R/R but it says switch meter to Diode Test Function. I don't see anything on my meter like this. I have two functions that I have no real clue what they are: hFE PNP and HPN/LED All I can find out on the web is they are for testing transistors. Can anyone tell me how to do the the diode test or do I need a better multimeter? In lieu of being able to test the R/R I swapped it out with the original OEM R/R. NO difference in voltage (as listed above) noted. Thanks Link to comment Share on other sites More sharing options...
Tightwad Posted August 2, 2007 Share Posted August 2, 2007 replacing it with a known good one is a pretty good test. The diode indicator is a line with a triangle on it. I would test your battery seperately, it may be bad and absorbing all the charge. Check voltage at the R/R(not the battery) and see what it shows there.

My meter has a setting in the Resistance section labeled 2K/then a horizintal line with triangle plus a verticle bar. But the chart say it should read in volts. Since the R/R should be good I begin to suspect the battery. I will replace it, that is the cheapest of the replacement alternatives. I still wish I could test the R/R diodes.

Guest Posted August 2, 2007 Share Posted August 2, 2007 Can anyone tell me how to do the the diode test or do I need a bettermultimeter? As long as you can measure resistance with your meter you can check diodes. Think them as one way electrical valves - one direction will have low resistance, one direction will have high resistance. Here you go with pics...Meter check of a diode (OT - For those that know hydraulics the schematic symbols can be confusing) Link to comment Share on other sites More sharing options...
