So, without the proper tools, hard to do a good job. I have a rather cheap multimeter; not the dirt cheap one, but not a Fluke neither... So I cannot go below 1 ohm precision. But my coil is showing as a 4.? ohm. I am going to treat myself with a proper Fluke multimeter, unless you guys have a recommendation for another serious multimeter
Now on the voltage: running with moderate rpm, batteries fully charged, alternator excited, I read:
- alternator pos to ground: 14.5V
- coil pos to ground 14.4V
- voltage between coil positive and negative: 6.6V
So questions:
- on my coil negative, I only have the Electronic ignition wire. Is that normal? Should the coil negative be wired to ground? ((Neil's drawing show no ground on his E-3))
- is having a 4 ohm coil mean that I do not need to install that resistor on the positive wire to the coil?
Thank you !!
