HELP PLEASE :) GT to G40 confusion

[dekerf1996]

I would have a go at what Andy has suggested. Had this problem with two of my conversions, the wire blocks coming out of the fuse box appeared to be connected fine, but in reality they weren't.

Ended up disconnecting and reconnecting them a few times and they eventually worked. All it takes is the right/wrong wire not to be connected and you get no power to the engine wiring and therefore it won't turn over. Had my lights working as that was connected ok
