Has anyone replaced the Italian CT elettronica AL6300 split charger on a 2002 Fiat Mobilvetta Driver 52 motorhome?
I have 240 volt AC input but no 20 amp DC output. Consequently, the leisure battery loses charge on site when hooked up. The relay from the vehicle battery system is ok and charges the leisure battery when on the road. The 240 volt supply to the sockets and fridge is ok but the interior lights go dim on site because the 12 volt supply is being depleted.
I have talked to an auto-electrician who suggested that a 20 amp Durite charger might be a suitable replacement (3 pin AC input and two screw terminals for the 14 volt DC output). However, we are both at a loss to know what the third output terminal (with one red wire connected through a push connector) does.
With the charger in circuit, the main control panel lights up but disconnecting the third output terminal doesn't make any difference to any of the lights on the control panel.
The only fault on the control panel is that the 240 volt telltale doesn't light up - it may have failed when the charger burnt out but it is not essential as I know when I am connected to a hook up and can put a tester plug in to check on European sites where polarity might be reversed.
I have opened up the charger casing, changed the glass fuses (which blew immediately I reconnected the charger) and cleaned up the PCB and contacts but my auto-electrician thinks that it may be a burnt out capacitor. However, he doesn't work on 240 volt systems. All the external wiring is ok - there is 240 volts going into the charger and the DC side is feeding back over 12 volts from the leisure battery. The issue is the failure of the charger itself.
It looks to be a simple exchange - if something like a Durite will be a straight swop for the CT elettronica unit.
Anyone with any ideas?
Thanks
