I've owned this 86 f350 6.9 for about 30 years. I always seem to be fighting with hard, smoky starts. I went to manual button 5 years ago and it's been better. I run the plugs for 8 seconds and then crank, I always feel like it needs more but I'm so afraid that I will burn them that I just let it smoke and then with a couple 2 second jabs on the button it cleans up. Last week after sitting for 2 weeks in hunt camp it smoked on startup really bad, so I checked the plugs when home and found just one bad plug. It just seems like a really poorly engineered system that can burn plugs so easily. Yes I run the Beru's. Here's my question, Why can't I just lower the amperage way down on the system to the point that they won't burn out, yes I might have to leave them on for a minute or two but I'm fine with that, it only only gets started once a month. I got the idea watching a video a few years ago. A guy was trying to show how durable the berus where, he hooked them up to a battery charger and left them glowing for like 30 minutes and they never burned out and looked to glow bright. So I started running my manual switch for 15-20 seconds and it started great--for a few times and then no start, the plugs were burned out.(laugh here). So I did the test on some new plugs again and found that I could leave one on the battery charger for half an hour and it wouldn't burn out, but if I hooked it up to the engine battery(more amperage) they would burn out in 15-20 seconds. They don't burn out they just won't work again after cooling down. So why not find a way to lower the amperage to the system and be able to run the plugs long enough to really warm the chamber and not have to worry about over heating the plugs? Thoughts???
