Ignition coil resistance values

[Roland Alcock]

I gave up on my LED bulbs. They were flickering or not lighting. 

I put it down to insufficient electricity due to voltage drop by the time the juice arrived at the light. 

I could overcome this with meticulous attention to the wiring or using inexpensive little voltage converter pcbs which filter out the noisy A7 electrical noise. 

It was easier to revert back to normal bulbs as I hardly ever drive at night. 

I also have another (unproved) theory that 6v led bulbs are really 12v ones which don’t work very well below 5.75 volts.

It seems the values are within the acceptable range and the car is running well so I think both coils are useable.

I must have a fairly “dirty” (electronically) engine which causes interference with the LED lights. I have a .22 microFarad ignition condenser on the +ve coil terminal which seems to solve the LED flickering but I wanted to check in case anything else was causing problems. 

Any advice on suppressing interference gratefully received  .

I guess A7 engines are prone to electrical noise.
