Setting timing on a piranha ignition

(1/2) > >>

gordo:
Does anyone know how you check/set the timing on a piranha electronic ignition. Tried looking everywhere for a manual but no luck. Cheers Gordon

K2-K6:
Most electronic systems required a strobe linked to the HT leads to check them when engine is idling as without this you can't easily see the trigger point.

If you mean markings? Usually when pulsed with strobe you'll easily see something that can be matched to the crankcase TDC casting mark.

Not sure if that's what you meant?

gordo:
Cheers for the reply but that's what has me confused it's a light activated ignition from what I can gather so I can't use a strobe.

K2-K6:
Have you tried it with a strobe as the HT "flash" should come after the trigger circuit has completed so there should be nil crossover in theory.

Is it an light onto sensor to trigger or a chopper disc making a light extinguished trigger event?

Have you seen it (the strobe output) interfere with triggering?

If you can get a voltmeter probe into the plug that connects to the loom you should also be able to time it on that by going earth probe into plug and pos probe onto battery pos to see it switching and check that against timing marks.

Johnwebley:
can you get someone to control the throttle,while you use the strobe,

 if you hold the  strobe in one hand,and a piece of card to hold over the  trigger area ,

so as it runs,you can check the advance,and shield the trigger from the flashes of the strobe.

 is that possible??
