Title: Timing Light
Post by: philward on November 26, 2016, 03:50:21 PM

I;ve bought a Aquaspark 3000 light to replace my 1970's timing light. Unlike my 70's light (replaced because its light is 'blurred' now) it has an induction connection for the HT connection (instead of an inline HT connection to plug/cap). When I connect the Red LT connection to the point and black LT connection to earth then press the trigger switch, the engine goes onto 2 cylinders - no strobe at any time.
I'm no electrician but there's little to the basic principle of how a strobe works. Is the new strobe duff or is something obvious I'm missing
Any idea's

You should connect the red to the live terminal on the battery and the black to the earth terminal, you are grounding out your points which is why it's dropping a pair of cylinders.

Thanks Kevski - common sense when you explain it! Doh!
Thank again
