My 84 300SD doesn't appear to be charging. I put a DVOM across the battery and it shows just over 12 volts with the engine off or at any engine speed. I have had the battery and alternator checked and they checked okay. I ordered a new regulator and when I pulled the old one the brushes are fine. They have very little wear. I did not install the new one. Are there checks to the regulator/alternator that I can perform with a DVOM?
I checked the connections at the battery and also at the alternator and junction block. All the connections are fine.
The charge light goes out as soon as the engine is started but the ole girl left me at the market with a dead battery so something isn't working.
I did check for voltage drain at the battery and when connecting the meter between the neg cable and post it shows battery voltage. I removed each fuse and each relay one at a time and it made no difference. Is there another area I need to check?
