Curtis 1244 Controller 'Precharge Fault'

Are there any Curtis controller experts out there?

I may have (rather stupidly - not double checking the pack was isolated before tinkering) damaged my 1244 when I removed a (coil-damaged - old unrelated issue) relay powering the DC-DC converter in my 2007 (DC sepex) Aixam Mega City Electric. I think the pack +ve lead that was disconnected from the relay shorted out to ground and now the controller just gives the '3,3' fault code which translates as 'Precharge fault'.

I have some reasonable DIY electronics repair skills and pretty good tools and testing equipment (and a spare working Mega City) and would like to try to fix it, if possible. My remote location (Isle of Colonsay, west coast of Scotland) makes any other method of repair a bit impractical - short of posting it off to someone else to fix at, no doubt, vast expense.

Any thoughts/help would be most appreciated.

Regards, Martin Winlow.
