Ive got a XTL5000 that I got in a lot of other equipment, when I plug it in it shorts the power supply. Is there a protection diode close to the 12vdc source input on the radio? I haven't opened it yet, but I plan on it when I have time.

Any help would be appreciated, I don't usually fool around with the ASTRO 25 stuff internally, I usually just send back to the depot, but this ones seen its fair share of age and use.

Thank you,
