Went to start the diesel today, just to charge the batteries. Started up just fine, but I noticed right away that I had no RPM indication. That was unusual. Then when I went to check battery charging--voltage read 12 volts. No output from the alternator. I scratched my head, knowing both problems were alternator related.
I let the engine run at low speed for about 15 minutes just to warm it up. Then I ran it up quite a bit. Once I hit a high RPM the tachometer came back online. Went below and checked battery voltage and saw that the batteries were now charging normally.
So, in the end all is good. I'm just wondering what happened electrically / mechanically.
