Spark Plug “tell tale” Lights

Whilst at the NEC Restoration Show I managed to do a bit of bargaining to get 8 of these spark plug tell-tale lights for a discounted price. A lot easier to test the spark than using the one at a time.

Tested the plugs and all definitely ok. The video does look a though there is a problem but I think that is something to do with the frequency of the video framing ….. the plugs were all sparking with no misses. So now ruling out the ignition system causing the misfire.

It’s not a regular misfire – it is a random misfire so again pointing to a fuel problem.
