BCD536HP blows fuses in truck

[ttravlos]

As the title says - I've got my 536 mounted in my F150. Two times now the 2A fuse has blown. Not using the accessory wire, just power & wired so the line is live even when ignition off.

The first time it happened I thought it was because I had not powered off the scanner while starting my truck. I've been diligent now about making sure to power down each time I get out of the truck. This time I'm not sure when it happened. It wasn't while the truck was on, because the radio didn't die during driving. I turned it off, shut off the truck. Came back to the truck, radio is dead, blown fuse. Is this a common issue with the 536 in a vehicle?

Not common at all. Check the installation of the wiring for the scanner first. That includes making sure that the black lead is well connected to a ground source.

Check the hot side for being damaged, and touching the body.

My 536HP is on 24/7 in my Chevy and it is fine. It is wired direct to the battery and a Meanwell Voltage Regulator so it doesn't reboot on engine start.

I stand corrected this time - I checked the fuse and it is good. What I had to do was unplug the 12v power connector and replug. Then the radio booted up almost normally. I say "almost" because I had to reset the backlight. It was off. Everything else seems normal now. I may have to add a voltage regulator.

Thanks for the replies.

I do some of those tricks too. Don't feel.

You want the step-up converter as suggested -

SD-50A-12: 50.1W Enclosed DC/DC Converter Input Voltage Range: 9.2V-18V: Mean Well

This will take anything down to 9.2 volts and convert it to 12volts up to 4.2 amps. Should be plenty for engine starts....unless your battery dies....

This solution was posted an while back by another member.

I just ordered two and can't wait to not have to shut the scanner off....

Yes, that's the one I've ordered.

Just to clarify - I did have to remove power from the radio before it would boot up.
