Thankyou for your response!

Yeah, this was after a charge, the charger wont allow me to plug it incorrectly as male-female so I guess that confirms it was plugged into the right place when charging. The batteries were low on water, this was only picked up after the charge, not sure if that has any effect, after topping up all batteries and charging the voltage and current look OK, and when it turns on (with FA code) the battery shows 90% full.

I cant see any other places there could be a disconnect, but happy to go and have another look.

There are some notes on this forum about checking the resistor under the battery : https://www.forkliftaction.com/forum/code-fa.aspx?t=8562#:~:text=Code%20FA%20is%20RAD%20%28Resistor%20Absorber%20Drive%29Disconnected,Posted%2024%20Feb%202012%2001%3A26%20Reply%20by%20robert_c but this is a different model.

I have checked the easy to get to fuses (under the dash), but i think there is another fuse board in one of the side panels, i can take a look in here too and check...

Again, thanks for your reply, if any further insight, please shout!

Cheers!
