A few questions. I have a 427 that is showing signs of not enough electricity - hard start, dying when increasing throttle. Some suggested a ground issue, but I had someone also tell me it could be the resistor that’s failing. So… some questions…
How can I test my existing one? What are the specs ?
If I needed to purchase such an animal, where might I find one?
My current one has a friendly “+” and “-“ on it but what about a spare I have with no markings on it?
Here’s a pic of my current one..n
Ok… back on this subject after a while (if someone tells you that you should try pneumonia out for a spin… take a hard pass).
Ok… let’s add a little more info to the original article that Char was kind enough to add, and to this post.
starting cold, engine turns over fine, and while not as easy to start as my port engine… it does… no hesitation just turns over and will start.
Pulled off the cap, rotor, and plate and checked the flyweights… turning the rotor I can see the flyweights both move out, and repressing the rotor they both return as expected.
Changed my Mallory Unilite ignitions from one engine to the other.. issue persists with the starboard engine. Diagnosis would tell me the electronic ignition is fine.
Starting the engine and letting it run for about 10 or 15 mins… during that time I let it idle, then recede to 1500rpm. Reduced to idle, put it in gear, reved to 1000rpm. No issues. I did not go longer but in other instances the longer it runs in idle or near idle the more likely it is to die when I put it in gear or apply throttle.
After the 10-15 mins of the above, I turned off the engine, tried to restart and was not able to get it to fire. While trying to start the warm engine it’s labored. (Adding a video)… this is not the case cold as mentioned above.
Ok… so, the diagnosis continues… any ideas with the added info?
