hi all well some humble pie !!had the rear lights earthed via body,decided to run from earth point in the light casing (though there wasnt any in first place ?)when i was doing work i took out bulbs (heres the embarrassing part) one of the bulbs was single filament DOH .so all working now spots took another few hours to work out ,a pull switch is being used on the -side ,i presume so as not to burn out switch ?although wiring is on a relay,did not have the earth connected in dash ,so they work now ,is this switching method ok ? will try and post a picture (keeps telling me too big ,how can i load up some pictures bulk ?)but this oil pressure sender i have teed of off idiot light was never wired up ,so at a loss if it even works (any tests i can do ?)it has 2 spade terminals ,no symbols.as previous post do i connect as a fuel/temp via voltage stabilizer?.but what would i connect the other spade to ,earth ?. im sure coil is connected as in photos i took before taking apart (1 1/2 yrs ago )but if it is -earth system is it +to dizzy from coil ? and finally i have doubts on my timing now ,after having the engine sat there for a yr .was looking at posts on timing (as i am going to fire it up soon :) ) think i have made a stupid mistake and set up timing with rotor pointing to WAIT FOR IT nmb 1 on the cylinder not the dizzy .all abuse accepted could kick meself, now reading posts if my rotor is pointing to 1on cylinder it looks like nmb 2 on dizzy if my vacuum advance misses dynamo can i turn dizzy to line up with 1 ??would this have any adverse affects ?if not a kindly explanation would be most helpfull thanks for any help john
