I had a free day today to spent it in the garage.
I'm on my 4th iteration of the under seat tray to hold the battery, ECU and other electric bits I want to hide. I miscalculated the measurements for the battery connector mount positions so had to re-drill some of the fixing points. Couldn't face making a 5th iteration so filled the holes which were in the wrong place with weld.
It all finally fits in place, still need to weld the side plates on, but the seat clears all of the bits and pieces. Indicators and lights all work except the headlight but not fitted that yet. I'll tidy it up a bit tomorrow. If I have time I'll put the rad back on and start on the headlight wiring. Turns out there is a loose connection on the original engine cut off button, couldn't work out why the ignition final stage wouldn't come on, took me a frustrating hour to find it.
