yes the PSD plugs are dual coil so they are self regulated. like those 6.2 plugs as well.
Update, so got the relay hooked up properly, I think it was before but anyway, it works. Go to glow for 7 seconds, nothing!
pull all the plugs, all 8 are dead. only 3 years old. SO i guess i must have killed them somehow before. I assume some were already dead from the hard starts in 50 degree weather.
Put all 8 new ones in, from orelieys, at least they got a 2 year warranty so if i burn em up ill try going with the delco dual coils..
anyway, glowed for 6 seconds, eventually coughed to life after 1.5-2 seconds of cranking. Im sure if i left them on for 10 seconds it would have lit off faster.
what was really itneresting, had my wife plug the truck in yesterday at 230 pm, and i got home 530 to start it to get wood, with no glowplugs on, i floored the fuel, turned the key and i kid you not, as soon as i turned the key thi thing roared to life. I dont knwo what happened, it doesnt even start that quick when its fully warm, takes 1 spin of the starter. Wish it always did that lol.
So, theoreticaly we should be all good now. THat western plow is rated at 800 inrush 150amp continuous, sealed casing. Funny that the western part number, which is made by trombetta and is labeled as a trombetta is 20 bucks at dealers and online, btu the trombetta marketed as a trombetta is 60+ online. Same exact product lol.
