Batboard

Hi folks
I have a 800MHz Dashmount Astro Spectra, always worked without a glitch until today when I brought it in from a vehicle thats been parked for 2 weeks, the radio was ice cold, and I brought in here to my desk where its nice and warm and hooked it up to make a programming change, and it wouldnt power on, gave me a Fail 01/90 and goes into a continuous self check loop...


Where do you guys suggest to start poking first? Maybe a fuse popped inside from condensation? first time seeing an error like this, I need this back in service asap

I just changed one out out today same code, VHF high power, remote W9 head got fried, probably when the car it was in was jump started recently.

Very common spectra error, been discussed here 1000 times. It means the control head and radio aren't talking to each other. A couple of possible causes on a dashmount:

Power to the ignition sense lead but not to the main power connection.

Internal fuse blown. There's a green Pico fuse near the front of the command board. One thing it feeds is the audio PA, so if it's blown check your speaker connections.
