Poor quality dizzy caps/screws too long
Posted: Tue Nov 01, 2016 11:12 pm
I recently received a shock when adjusting the timing on my car. I removed the cap and leads to see if I could find any obvious reasons for the jolt.
Looking closer at the top of the cap I could see a small protrusion on the cap, just behind where the leads entered.
What I discovered was that the screws inside the cap, which screws through and holds the ignition lead in place, had gone through the lead and then on through the cap! It hadn't cracked the cap, just pushed its way through the plastic.
So just a word of warning, either reduce the length of the screws, or be very careful when fitting, to ensure you don't screw them in too far.
