ICOM IC-7000 Low Power Output RESOLVED!

I've recently been using my Icom IC-7000 inside my house as a convenient way to listen to W1AW Morse Code practice sessions.  One afternoon, I was on 40 meters and decided to have a QSO with a fellow ham. I went to key and noticed that my power output level was peaking around 60 watts +/- or so.  Since I had the power output set at 100% (or 100 watts), I was concerned.  I knew that my antenna was good, the auto tuner had been successfully initiated and was operational.

Hmm, had I managed to break something?  Time to search the Internet for help!

It would seem that I'm not the only person who has had this issue.  The first answer was very common, something along the lines of:  "The IC-7000 needs 13.8 volts; anything less will affect power output."  I was already familiar with that problem - mostly due to my operation in my vehicle.  The IC-7000 worked great when the car was running, but when the car was stopped (engine not running), power output > 50 watts caused the unit to cycle off and back on.  Apparently, the solution for that problem is a "voltage booster."

On to the next "most likely" cause - bad fuses.  Really?  Bad fuses; corrosion?  Well, guess what - yep, that was actually the problem.  I found a good article by AB4OJ - Link Here -> Check out the heading "Low Power Output on Transmit."

I checked the 30 Amp ATC fuses and take a look:

Notice the nice dark corrosion line across them?  Yeah, I noticed them also.  I took a pocket knife and scratched some of the oxidation off the fuses, put the back in the fuse holders and yep, the IC-7000 went back to transmitting all of 100 watts.

Next step:  get out my dremel and buff the oxidation off the fuses.
