Icom warranty about to be put to the test!

The new 421 I bought to replace the Silvas has just packed up after less than half a dozen trips. Will need to wait till I can get into the console to check but it just switched off and stayed off when I tried to transmit for the first time on todays outing.
It ain't looking good

before returning couple of things to try
check all dc connections, may be a bad or minging contact.
worth checking ti on a stable power supply off the boat.

very strange to have an out of box failure.

I will Jon, thats why I need to get into the console. Unfortunately because I fitted a really big battery I need to remove the hatch and battery to get into the electronics as the battery is in front of everything and the whole hatch needs to be removed to get it out .
It was on and receiving and seemed to go dead when I first transmitted yesterday and stay dead, nothing showing on the display at all. It may just be a bad connection or similiar but will need to get in and look.

Well the radio was fine, just a blown fuse. The strange thing is not that it was blown but that it lasted so long through three VHF's.
The fuse was only a 3A one which rather surprisingly objected to more than 5A going through it when transmitting.
This same fuse has been operating the VHF for 18 months now without complaint even though all the radios fitted have drawn more than 5A transmitting.
In saying that fuses can be unpredictable, I remember one guy plugging in a faulty table lamp with a 3A fuse in it and it blew the 250A pillar fuse outside the building, bypassing around 4 fuses of larger and larger capacity till it got there.
I'll go away and be embarressed now

Mr Bear... I had a simular thing happen to me only ti was a Garmin GPS i was replacing rather than a VHF, i re wired exactly the same as the existing GPS had been only the new one wouldn't power up a quick call later to my Electrical genius friend Swifty and it was sorted, turns out i'd shorted out the switch somehow ? God knows how i'd done that, anyway its sorted now.

Ah, but I used to be an electrician making this doubly embarassing. I did consider sloping off and saying nothing but I suppose I need to take it on the chin after impugning Jon's radio's reliability
All I can say is these automotive fuses must be fairly robust to cope with overloading over so long a period...........
