I have a unilite that has been good for almost 25 yrs Tried to start no good.Ran module test showed open,orderd new one.ran test showed good.Still no spark.Changed to new coil,no spark,rand new ground no spark. Anyone?
unless you are running a cam with a billet gear, unlikely the distributor, or cam, gear is wiped. Billet cams with billet gears need a specific distributor gear
As noted if the rotor turns smoothly (not jerking or stepping) when you crank the motor over the gears are likely not the issue
When people fail to bolt the distributor down with the hold down the distributor can "lift" out and the teeth can get chipped but the car will stop running as the timing is then all off
When you replaced module did you pull Dizzy to do?
If so you sure you stabbed it back in right?
if this is a non points distributor (aka HEI) you want a "NON" resistance wire, not the stock resistance wire. Run a new +12vdc wire from IGN terminal on fuse blockI pulled cap and cranked,rotated good no jerk, retested new module test ok.Getting 9 volts from resister wire per instructions. still no spark.will move ground to manifold.Any other ideas.
Before installing the UNILITE® Distributor, make sure that your vehicle is equipped with an ignition ballast resistor (or loom resistance wire)if this is a non points distributor (aka HEI) you want a "NON" resistance wire, not the stock resistance wire. Run a new +12vdc wire from IGN terminal on fuse block
with that said my car ran with the 9v resistance wire when I put in a Pertronix kit but I did swap that wire out for a copper core feed from IGN and just taped the white resistance wire back into the wire loom
didn't know there is a bench test for the module other than confirming its getting +12v (or 9v from resistance wire) and ground is good
