Thanks JP. I wasn't cranking nor did I check the ohms. The multimeter was flickering around 10/11v for a few seconds but then would drop down to 1v and flicker around 2/3v for about 4 / 5 seconds before jumping back up to 10/11v. Would this show coil is on the way out or should I also do a resistance test? New battery was fitted to the car about 6 months ago and this shows a constant 12v
