Re: [EVDL] leaf 2011 bad diode charger

[Cor van de Water via EV]

The 2011/12 has the charger behind the rear seat on the passenger side, not
a convenient location to open and replace parts.
Don't be afraid of pack voltage, as long as you leave the car off, to make
sure you can disconnect the 12v battery as 12v is required to engage the
two contactors that interrupt the high voltage in the battery enclosure.
Use a multimeter to verify that all pack voltage has disappeared from the
high voltage bus to the charger, the you can safely work on it.
I was a bit afraid of the coolant loop that comes from the motor
compartment, but while swapping the charger, only a few drops were lost.
There is no pressure on the coolant.
Note that the charger is above the floor, the coolant lines below the
floor, behind the battery pack, above the rear axle.
I no longer have the broken charger, because another EV'er has used it to
fix his own charger.
Hope this helps,
Cor.

can that doide be replaced by just taking a cover off or does the whole 
charger have to be removed/ cooling lines, disconect pack voltage etc..
