Re: Voltage regulator location
Thanks AVB. I am learning fast and trying to put 2 and 2 together. Y'all correct me if I am wrong. I understand that on a system with a separate regulator the way to check the alternator output is to disconnect the alternator (white plug) run the engine at full throttle and the voltage at the plug should be 30 VAC or more. That voltage will then go to the regulator where it is converted and regulated to about 13.8 VDC or something like that. But since I don't have a voltage regulator in the conventional sense, the alternator still initially produces AC voltage but puts out the proper DC voltage at the white connector because of the inline diode. Am I correct so far? I did some more thorough checking today and here is what I found. I checked the inline diode and found it to be in order (dead in one direction and throughput in the other). While I was at it I checked the alternator output before the diode and it was a convincing 46.5 VAC (and nothing at the VDC setting, which of course there shouldn't be). Now I checked the voltage after the diode at the white (still disconnected) plug and it showed 11.3 V on the AC setting of my voltmeter and 23.6 V on the DC setting. Now I tested the charging voltage at the battery posts after everything was back reconnected and normal and the reading was 5.6 VDC. Battery posts and cables are clean and make good contact. The battery voltage by itself was 12.3 VDC. Tomorrow I will attempt to trace and check all the wiring, its connectors, fuses, ground connections etc. for corrosion and other short comings. In the meantime all good ideas are appreciated.
