2006 mizar gtl living battery charger (1 Viewer)

[Brianabbot]

Hi everyone, we recently bought a mizar living and ive noticed my main battery goes flat after a couple of weeks despite being plugged into a mains supply, my local dealer has said that only the leisure batteries are charged on the mizar. On my last van the charger did both leisure and engine battery and I wondered if I could fit a split charging unit to set this up on the Mizar, or if the van will indeed charge the engine battery but I need to set something on the control panel like my last van.
Any help greatly appreciated
Brian

I used to have a CI Cipro of similar vintage, and whilst I cannot be certain my recollection is that both batteries were charged when plugged in. I would have thought the mizar would be the same.

But even if not, the battery should not go flat after 2 weeks. Either the battery is faulty or there is a charge leak somewhere (inside lights? radio?) You could try disconnecting the battery to see if it loses charge then.

if nothing can be done regarding the control panel there is a cheap and easy work around.

take a wire, capable of 30amps for safety, between the hab battery and engine battery positive terminals.with a 20amp, easily accessible, fuse in the circuit.
take another wire from the hab battery negative terminal to a chassis earth or the engine battery neg terminal.
this set-up will charge both batteries from the leisure battery/charger.

you will need to remove the fuse when you start the engine or the fuse will blow and dont replace until you are back home/on hookup or it will drain both batteries when in use

Hi Brian, We also have the Mizar but dont think there is a way to charge the engine battery from the on board charger.

The display panel shows the engine battery voltage but i dont see any change when the onboard charger is on it only rises with the engine running.

I have 85w solar on top and a battery master fitted so they are both allways in tip top condition :thumb:.

The next van is going to be a self build and i intend to fit one of these http://www.victronenergy.com/battery-isolators-and-combiners/cyrix-120a-225a-425a/

Good Luck.....Ralph

Hi Brian,

I have two cigarette lighter plugs either end of one cable; one plug goes in the vehicle dash socket and the other in a rear socket off the leisure battery. It is a quick-n-dirty solution to your problem that needs caution. There are 10A fuses in both plugs that can blow if:-

• either battery is very flat.
• one plug tip touch the vehicles metalwork when the other plug is connected.
• You try starting the engine.

Cheers.
