hi andy,
building alterations consist of puttin a beam in to support bricks above french doors(theres a main beam 4" behind)
then enlarge whole wide enough for pop and room to work.
contruct stud work along the side an fit window and door(bought cheaply of ebay)
back to pop,
started going through stuff for mot, flashers flashed about 120 times a minute,slightly fast!!!
due to this me thinks.
i tried a yank one i've got here and they flash at a more normal speed, but its not got a feed to warning light.
also trying to get hold of a stock pop ignition switch or similar in good condition, the one thats fitted gets hot with ignition runnin through it, lights are integrated into this switch and still work ok,could it need a relay of some type to stop full current runnin through the switch(which is the 6v original as its now runnin 12v)
cheers chris.
