Fat Boy 4 pill die?

[Prof. Base]

A buddy of mine said that his Fat Boy 4 pill (not biased) died. He wasn't transmitting when it happened. He said "I flipped it on, nature called, and when I got back the led was off. Now the led just flickers and goes out when it's powered on and the fan doesn't come on." He said there wasn't any smoke or electrical smell and that the power supply tested out fine as did the fuses. I told him it might need a ride to Fat boy for repair.

Might be the power switch or maybe a bad / loose power connection?

That's what I was thinking. I'll know more when I can make it over there and take a look at it. I'm no "amp tech", but maybe I could spot something obvious.

Cold solder joints, a wonky fuse, loose wire. could be almost anything.
Poke around with a stick or pencil

The led is hooked straight to the switch, gotta be something simple. The switch allows the keying relay to engage when the radio is keyed. Switch power should come straight from the 12v power strip that the main power wire goes to. So basically the power switch is just an enable. Doesn't actually turn any thing on when switched, except the led.

Are they still building Fatboy amps? Have not heard much about them in quite some time.

The switch powers fan, LED and keying circuit. If switch bad or cold solder joint. That will stop everything

Switch was fine. Turned out to be a faulty, cheap fuse that fell apart, but was still allowing only 2.3 volts to pass through. Ahhh...it's the little things that'll get ya.
Thanks guys for all the advice.
