Do I need to worry about ZD('s on my truck I havent got them yet, but I put a manual button on it, and it worked great till the relay crapped out. 1990 f350 7.3 diesel 95,420 miles
15 seconds is all I'm gonna hold em for.I wouldnt have thought it would have mattered because you can limit the seconds down to 10-15 seconds I believe I read.
The stock glowplug controller system will glow them hot for a while, then continue to "cycle" glowers to prevent them from burning out. The cycling cools them down a bit and continues to aid in cold starting until chamber has built enough heat to burn the air/fuel mix. This is why I prefer the stock system
The stock system for me hasn't been ideal, it would work one day, then two days later it wouldn't do nothing at all, After I put that manual button on there, she only turns over 2 times before firing.
5-10 seconds, but depends on the plug. on a good but high-mile compression IDI it only took 5-7 summer or winter.
Nothing simpler than push button control - ZD9 applies to any type of "bullet" connector glowplug whereas ZD1A are spades. Bosch work great with push but not controllers, berus seem to work better with controllers but work fine with push. Reason being they run a little "cooler", and can take larger amounts of time before burnout.
15 with bosch will kill them in about two winters, if they are bosch and it takes that long you have air intrusion or low compression... 5-12 bosch, beru can take more. Engine should start just fine with a single glow, not glow + on/off/on/off... But you can smooth out the idling if its real cold by manually doing the cycling too. Or rev it
What 12 volt glow plugs are good?Why not check out some 12v glow plugs? Here's the problem. You are relying in under sized wire as a current limiter. Everything is working fine and one day, unknown to you, you lose a glow plug. Now those 3 good ones left on that wire are taking 33% more amperage or all seven are taking 15% more amperage the next time you start the truck. Then you keep holding the same time as you always do and others eventually burn out from overheating or you give them just a couple more seconds when you notice it didn't start quite as fast. "they're getting old, you know," thus accelerating their demise.
3 months later you are complaining that brand xyz don't hold up.
This is all just fantasy on my part. But what if?
