So hello and thanks!

My early 260Z Has some problems i'll give you the specs..

*Stock motor early 4 screw SU's rebuilt by ZTherapy .

*Mallory Unilite Distributor mechanical advance and some old Mallory coil that gets pretty warm when running.

*I added light and turn signal relay kit some time ago.

Everything else is stock.

My problem is the coil is only getting like 9 to 11 volts max sometimes and makes me think i'm no getting good spark.

Also sometimes car will crank fine, but won't spark unless unless I add a Jump box.

What should I do?

Is there a newer better ignition system I should be using that will help clean up and help car run better?

Is there a shop or any one chicago who can help really dig into these car and iron out my issues?

1. Did you remove the ballast resistor?

2. At what times are you getting the lower voltage at the coil? Just at starting? While running?

3. How old is your battery?

4. Check your battery voltage while the car is starting and while it is running. Does the battery voltage dip at start? How much?
