Older Yamaha Generator repair help request
Hello All, It's been a LONG time since I have visited this forum, but I do often think about it and have sent several RVer's here over the years. My life's situation has changed dramatically, and...

YAY ! You guys are GRRREAT !
I watched a couple of youtube videos on Flashing the generator with a drill or hand grinder and gave it a try.
I used a large Dewalt 90 degree hand grinder and gave it several spins.
At first it did not seem like anything was going to happen and I was getting a little discouraged. I tried for about 4 or 5 minutes and was about to give up, thinking there must be something more involved. Frustrated, I gave it a couple of more tries by rolling the wheel of the grinder across some plywood quickly and WA-LAAA ! ! ! It Worked ! the generator's power light came on, the voltage meter was registering 120v, and the grinder powers up just fine !
I am a happy HAPPY man !
I let it run for about ten minutes, and did a bit of grinding with my small Dremmel Tool. I then turned the genny off and back on a few times, and all seems well.
I then let it sit, turned off for about 4 or 5 minutes, and started it back up.
This time, after I fired it up, it did take a few extra seconds, (maybe 20-30 seconds)before the power light and voltage meter showed power output.
So I guess my next question is,
Should I now run it for an extended period of time? under load ? Heavy load, or light load ? or does this not matter now, and I should expect the field to remain excited for a reasonable amount of time now ? (Days/weeks ??)
I've always known that any generator needs to be run under load periodically to keep it in good operating order,...
.... but I did not know WHY.
Now I do ! YAY !
THANKS SO MUCH for the tip, I'll never forget that one.
Maybe someday that knowledge will come in handy to save another sole some unnecessary repair costs.
Happy trails to all.
