Another rookie mistake

[Jewellbags]

Only had a moho for 3 years but , couldn’t fathom out why the 4 month old cab battery was draining so fast . Even took it to a dealer who took a look . My radio header unit is wired to avoid the ignition (so we can listen with the ignition on) . Thought turning it off a flipping down the fascia front would stop the drain but it dawned on me it had to be completely removed - which I did and solved the issue - who knew a radio could drain so much charge .

We live and learn - slowly

What brand of head unit is it?

 

[Jewellbags]

Pioneer , a bit crap and over complicated TBH (should be installed in a boy racer car ) .

Pioneer's are renowned for high current draw on standby. Many a Carthago owner has woken up to flat starter battery, they wire it via a switch on the control panel which cuts the power to the unit but if you don't turn if off you have a problem.

With the quality of some Bluetooth speakers out there these days I don't feel you need to worry about getting an ignition free live to the head unit.

Just fit a switch in line with the main power feed (leave memory power feed connected). It's when they are left on for long periods you get the problem.

Also fitting a Batterymaster or similar will keep the starter battery topped up from the leisure battery.

Alternatifly rewire it to the leisure battery but still fit a switch to isolate the main power.

My pioneer runs off the lesiure battery. Useful for using it when parked up.
