Drdialtone Posted May 20, 2012 Report Share Posted May 20, 2012 OK, I'm at my wits end... I've had three failures resulting in tows home. First, OK, vacuum advance fails, and loose screw with points and condenser wire. Fixed, running fine. Second time, tiny wire in distributor broke, OK this make sense, made new one, all seems OK again. THIRD break down, no juice to the plugs, just POOF dead. Checked all connections, look good, no signs of shorts, just DEAD. Juice from the key to the coil, but nothing past that. Coil maybe? (scratching head). Any other common issues with the distributor that I am missing? Haven't replaced the coil yet, guess that is next. ARRRGGH! Quote Link to comment Share on other sites More sharing options...

greg g Posted May 20, 2012 Report Share Posted May 20, 2012 condenser? Also check the terminal where the coil wire attaches to the coil. Maks sure there is no pathway to the dist body. A short there renders points usless. Also make sure the wire in the dist is ot grounding to the dist body. Quote Link to comment Share on other sites More sharing options...
Robert Horne Posted May 20, 2012 Report Share Posted May 20, 2012 Recently my Coupe stalled in the driveway. The rotor button tip looked very bad. A little sandpaper to the tip, and car started right up. I keep a little test light, sandpaper, etc, in the glove box, and now, with a spare rotor button.

Dodgeb4ya Posted May 20, 2012 Report Share Posted May 20, 2012 That tiny wire in the distributor needs to be made from a special extra fine strand wire because it flexes so much, otherwise it will break. Bob Quote Link to comment Share on other sites More sharing options...

Replace the coil and keep it as a spare in the trunk if the problem persists, but it sounds like a bad one. 6v or 12v? I feel your pain! I can't seem to locate the reason I have a miss. Replaced all ignition parts like the rotor, cap, condenser, wires, plugs points and still it persists. I still haven't timed it (kinda scares me to take the distributer out and place it in correctly), but that's all thats left. If that doesn't cure it I don't know what I'm gonna do.

Niel Hoback Posted May 21, 2012 Report Share Posted May 21, 2012 DCurrent, if you think you've exhausted the electrical problems and it still has a steady miss, isolate the cylinder by shorting out each plug individually and then check the compression. If its even with the others then consider it good news. And start over. Don't forget to look for a vaccum leak at the manifold gasket too. Come to think of it, a leaky wiper hose did that to me once. Scored three Felpro head gaskets today for $20. Wooohooo. Quote Link to comment Share on other sites More sharing options...

flatheadtim Posted May 21, 2012 Report Share Posted May 21, 2012 (edited) If you have power to coil, check trigger side coil with test light it should flicker (turning on and off) when turning over if flickers could be coil or condenser. Also coil wire could be culprit but usually I would do condenser first then look at coil issue. Condenser cheapest.

Plymouthy Adams Posted May 21, 2012 Report Share Posted May 21, 2012 usually a mechanic will check the coil and condenser with a meter if point condition warrants the checking of capacitance...you folks make this simple circuit too complicated..

The coil is the only thing that has not been replaced. Good idea to go ahead and replace, and keep the current one for a back up, along with a spare condenser, points, rotor, cap, and wires!

Drdialtone Posted May 21, 2012 Author Report Share Posted May 21, 2012 I believe my distributor is an Autolite...anyone know if there is an alternate brand? I want to have the Petronics HEI conversion, but they don't do my existing distributor. Any ideas? Anyone have one they would like to sell?

Not meaning to contradict you but I believe you have to check the condenser with a megger (not many people have these) thats to complicated. I would think if you have trigger (on--off from points on the points side of coil with test light flickering while turning over eng.) and 12 volts to coil on other post then you should have spark out of coil if the spark is intermittant check the condenser if not probably the coil. It takes me 2 minutes to check this with a test light once at trigger side of coil then at 12v side of coil then output high kv. You can also ohm the coil but this is not always reliable.

I use my fluke DVOM plenty but a DVOM will tell you, you have 12 volts on a single strand ready to break where the test light will glow dim indicating a problem.

I want to have the Petronics HEI conversion, but they don't do my existing distributor. Any ideas? Anyone have one they would like to sell? So, can anyone tell me the model number/brand of distributor that works? Also, was Delco or any other brand of distributor used versus the Autolite that I currently have in my flattie?

Drdialtone Posted May 24, 2012 Author Report Share Posted May 24, 2012 So, are there no other distributor options besides the Autolite that came with the engine or the slant 6 distributor? I'm hearing that the slant 6 distributor requires 12v, and I don't want to change everything from the 6v system that I already have in the car. Any other distributors that work? Looking for as many options possible, and trying to maintain all of the other systems...am I up "you know what creek?" ;-> Quote Link to comment Share on other sites More sharing options...
