Yaesu Fl2100 bypass may be stuck ??

With any luck, only the fuse.

Sounds like you turned it on without defeating the cover safety interlock. Don't do that.

Actually, if you're not sure what you're doing, don't ever remove the cover without the AC power cord unplugged.

 

You'll have blown up the resistor that is there to discharge any residual HT when you remove the mesh on top of the PA compartment. Obviously you should never do that with the power on !

Hopefully you haven't done any other damage, although you may have blown some of the rectifier diodes.

As others have said, you really should read through the Manual before you do anything (if you didn't get one with the Amp, you can easily download one online)

And you are much better doing resistance checks with the power OFF than doing anything with the power on. You need to be very careful, as one mistake with these kind of voltages and you will be Silent Key.

And please answer these questions:

1. Are the Links in the right place for the Mains voltage you are using?

2. What does the HV voltage meter read?

3. Does the relay go over REGARDLESS which position the STANDBY/OPERATE switch is in?

4. What is the PA Standing current?

anybody notice anything

 

1 links correctm for 120
2 hv reads in middle
3 i am using a ameriton 704 i also tried just touching a wire between rly and g
4 the only thing that ready is the hv gauge in the middle

thx

 

What's the HV meter indicate "in the middle?"

Shouldn't the HV be around 2400Vdc? What's it indicate?

 

the meter stay in the middle when i turn it on

 

Where the red line is?


That indicates trouble somewhere. It could be a few things. How comfortable are you with a multimeter and soldering iron?

I can only judge the situation with the pictures you posted, but it looks like that amp has seen hard times and a corrosive environment. It will take some careful work to get it going.

 

the needle is 1 click above the 2
As soon as i give power relay clicks.
I can use a solder iron, not well, but it will pass. I have a meter, but what do i measure ??

thx for help marc

I think you better not do that.

 

If the meter has 2 in the center it sounds like the meter has been replaced.

Is this jumper installed ?
