Thanks for the replys. I've been working way too many hours since the end of August, I got this car Labor Day weekend, and I haven't had time to really mess with it. I may be jumping the gun placing the blame on the Crane unit(fear of the unknown?) I just have a hunch that this cars issue I'm having is ignition related. It has a crappy idle, and I'm 99.9% sure it's not carb/vacuum related. It idle's like it has a half-dead hole, or running on 7 cylinders, but as soon as you get it up off idle, it smooths out. I know, it could be alot of things, but it just doesn't make the power down low that it should either. Like I said, I've been super busy at work, and I haven't had 5 minutes alone to work on the thing. But, with the posts so far, it sounds like mixed results with this unit. I've got a brand new dwell meter, and I've never had an issue with a good set of American made points:TU:
The way you describe the "half dead hole" at idle reminds me of my hair-pulling nightmare gremlin with the convertible a couple years ago. My problem turned out to be too much vacuum advance. An advance stop installed on the vac can cured the idle problem.
Tom I use Crane Xri in all my cars and they all work Great! Especially like the built in rev limiter for the stick cars.
I appreciate everyone's input:TU: Still quite a bit of confusion though....half say full 12 volt's, the other half say resistor wire.HHmmm I'm going to say that I'm almost postive if I put this back to stock with point's that it will run better than it does now. There is no bottom end, not like it should be anyway. Reminds me of a car that was converted over to HEI ignition, but run through the resistor wire. Hooked up with a full 12 volts is like a different car. When I go back to points, I'll let everyone know the outcome.:bglasses:
I have had 2 sets. My first set I let hit the limiter while doing some gear testing. When it hit the limiter ALL cylinders died. When it recovered I had 3 plugs fouled..all that fuel coming in on cold plugs I guess. For some reason I thought it would only kill a couple of cylinders...but the limiter in it seems to be very basic. The second set I bought seems to be fine but I have yet to hit the limiter with it.
Bumping an old thread... What was the verdict on this, Tom? Was it the Crane unit? Has anyone had problems *lately* with the Crane or Pertronix (1,2, or 3) units?
I am in the process of removing the pertronix,and going back to points. Usually the stocker ,the better they run.:TU:
I'm curious too. I'm still using points but have a Crane unit sitting on the shelf. I don't want to install it if it's going to cause problems.
I was having some weird electrical issues. I ended up removing the XR-i (before Stanton last year) and swapping to Pertronix. No more electrical issues (however I didn't keep the Pertronix in that long to determine if the XR-i was the real source of the problem). Or the engine either as I yanked the motor and put in the current engine which is running the M&H set up. btw, the M&H setup is REAL nice. With the Pertronix (1181LSCC iirc) I have to wait for it to "warm up" I HATE it as I'm running it in my 70 F-85. Sometimes it just cranks and cranks and cranks and cranks and cranks and cranks and cranks. And yes, it's hooked up correctly. The M&H, one crank and she starts right up. warm or cold.
i always loved my crane unit. just run 12 volts to it and run the matching coil ran it 6 years I only changed it to try the Pertonix 3 multispark unit. Funny thing is it looks like the crane unit- even the crappy rev unit adjuster?o No:
You all should get a good laugh out of this......but I sold the car before I figured it outo No: However, we ran a Crane in my brothers Chevelle, and it worked great,IMHO.
Pertonix bought out Crane's technology when they went out of business a few years back,so that Pertronix unit is basically a rebadged Crane Xri.
I find it weird all you guys ran 12v to with the crane kit... my in structions said to use the resitstance wire and if you did not have a resistance wire to wire in a resistor
I was having ignition problems with the Hornet, car wouldn't run. Replaced the Pertronix 3 and their coil with a set of points and a used coil and car runs fine. Ihave the Pertronix 3 in the ScRambler for three years and haven't had any problems with that unit.
I ran an xr-i with the matching coil on my 72 Cutlass with a warmed over 455. I used 12 volts. I fried the unit and put in points and a Mopar ballast resistor since I cooked mine. I'll be running the M&H like junior supercar in my F85 and '72 eventually. Matt
The XR-i uses the stock resistor wire, not 12 volts...as you found out:laugh: I guess the point is moot now, since the XR-i is N/A now.
my memory is foggy but I basically wired the distributor with the stock wires like it still had points. Then the resistor wire got fried and that is why I had to run a ballast resistor with my original harness. Not pretty but is starts any time. Matt
