Timing problems on the 450 Bomber

<< < (6/23) > >>

K2-K6:
Yes, as Roy in that a check for definite volt + supply is there, also a check of earth competency as well.

Seems quite simple to fit Mo. Have you got the leds to show there's power and switching going on ?

mo goldie:
hi,

yes checked all the earths are good and yes I have the led`s light up and when I try to go to time them as I said they do go out but Not at the LF mark they go way pasted it....... that's where I said to Roy about the timing marks. I have done a TDC with a Dial Gauge and marked the rotor so I Know where that is Now..... but still NO spark ?

royhall:
Is there no spark to either side? Is there power to the coils when ignition is on? This is very strange as the way it's built it''s like having two separate systems. For them both to fail, what's the odds. What's the common denominator here, what do both sides share. Silly question but you have removed the condensers haven't you.

mo goldie:
No spark to either side Roy, the two modules one blue one green get there power from the horn + wire and go from them two power the coils then what I can make out the two pick-up`s send the trigger the coils....... did you watch the video ?

as I say all wired up right just No spark ..... i did have hair LOL going like Yul Brynner Now.

Oh yes condensers have been taken off yes

K2-K6:
It is a bit weird to have no spark from the two separate units as Roy states.

The units (same as points) are only switching the earth wire to the coil  to make that spark. If the led is changing it should be doing that switch at least. It would still spark wherever the timing is set.

You can, with power to the coils, get them to spark by disconnecting THEIR earth from the ignition pack, then hold it against an earth scource, when you pull it off the earth they should produce a spark like that.
