Radios keep breaking

[Bowser]

So 12 months after replacing my previous aftermarket head unit, the replacement unit is doing the same thing - draining the battery.

Works fine, but its drawing about 1.2amp when car is off.

Am i just unlucky with these head units?

Anyone got a spare bluetooth one they want to sell?

It definitely didn't draw any current during the first 12 months of the new unit?

 

[Bowser]

No, as i kept checking and paranoid it was going to do it again..

Then the other day my battery died completely. I assumed it was the cold snap killing off an old battery, but after some checks found the stereo was at it again.
When unplugged there is barely any drain.

 

[Louis]

Did you use new adapters?

 

[Bowser]

No i didnt. the problem only occurs with the radio plugged in, so id have thought that is fault. As opposed to a plug or wire shorting out.

Do you think its worth a try?

Strange it didn't always persist but maybe worth trying a new loom from radio to oem radio wiring.

 

[Landyman]

What make is the stereo?

 

[Bowser]

I have the oem in the loft, will try that.

The first unit was Pioneer and this one is JVC. I imagine they are all made in the same place anyway..

 

[JamesBryan]

Do you have some dodgey wiring on the loom somewhere.

Is the unit turning off when you take the key out?

 

[Brigsy]

I would check that the wiring is ok/wired correctly

 

[Goodj]

sounds like a bodge on the power-wiring.

as above, new ISO adapter loom and HU.

 

[Bowser]

Had another look today, as i think the cold weather may have killed the battery.
Its drawing 0.15 amps with the radio plugged in.

That doesn't sound excessive, but not ideal from what i can tell. What do you think?

 

[Bowser]

Well i ended up getting another stereo, and its dropped to 0.04 amps..
I wonder how long this one will last.

 

[Louis]

Did you swap out the loom or just use the same one again?

 

[Bowser]

Same loom from the car, but im direct into the iso plugs. So removed the 2 into 1 converter lead i used before.
