:mrgreen:
last time working with leds i blow up on of them :mrgreen:
Pictures or it didn't happen.

The LED on the timing light shows it has power, now you just have to get it triggering.
thanks.if you could took a pic and put here.

It is a 'joke' or humor. It means that if there is no proof showing it happened, it did not happen.
I only thought it was funny, thinking about someone blowing up LED's. :D
But do not worry. You do not have to put pictures here.

haha!
it didnt actulyy blow up.
its color turned to black and a little smoke comes out of it :D

guys
last night i was working on the timing light
i conected the blue to gnd and the green into +12
and the black one to the oc1 from the wire that goes from driver coil into coil 1-4
and the light start flashing but when i rev up the engine the flash goes faster and then suddenly it turned of!!!
and then never worked!even in idle rpm.
any idea whats wrong? :geek: :cry:

Only thing I can think is these older timing lights are meant to sense the voltage through the plug wire and flash. Connecting the board up directly to a source for flashing might work for a bit but when it's working as an inductive light, it's isolated from back-EMF, and if directly connected it is not.

When working as an inductive light, clamped on the spark plug wire, it's only sensing the voltage peak in that wire.

When you connect the "trigger" for the light to whatever ignition coil directly, it is not protected from any reverse voltage that may appear on that signal wire.

Also, the older lights do not like "high-voltage" ignition signals, so may fail at voltages above 35-40KV.
