I Am Installing A New Alarm With Starting Capabilities Tomorrow And Was Wondering What Glow Plug Time I Should Set. Is There Any Possible Damage By Setting The Glow Plug Time Too Long? Thanks For The Help.
when you say set the timer do you mean the delay that it starts after you hit the button or does it actuall go in and mess with the glow plug timming.???..the glow plugs dont have to run very long at all...they get cherry red fast...they are just a dead short, running them for extra time will just shorten the life of them.
I have been wanting to install this to. The timing delay is between the time the device turns the ignition on, and the time the device turns the engine over to start it. The device does not mess witht hte computer control of the heaters... Does anyone else have an auto start installed?
I have the python alarm on my 06 and I just installed the 528t delay after a year of using the remote without a delay. Never had a problem starting up without it at home (so Fla) but i installed it before a trip north. Watch the time for the glow light to go out and that should be about the time to set the delay. Mine was around 4 seconds so i set it to 5 for the delay.If you are using a seperate time delay relay (DEI 528T) mount it where you can get to it easy and adjust as needed when it gets cold.
5 seconds is a good delay and more than enough time...most think if u jump in and turn the key skipping over the Glow Plug function it will damage then...not true glow plugs are only needed in cold weather...anything above 40-50 degs it should fire up on its own no problem...
they also stay on for about 1 to 2 minutes after start, you can tell when they turn off your lights will go brighter and the a/c fan speed will pick up.
I looked into remote start this past fall and decided not to put it on. The service shop I was going to take it too quoted me around $350 for a pretty nice system. It was no alarm, just remote start, but anyways back to the point of the topic. I asked the same question to him about time delay and he told me that it actually takes and input and when the glow plug light goes off on the dash is when the truck will try to start. I wonder if that isnt a better setup the the timer as it would be more like sitting in the seat? Just my $.02

I would have to disagree on this one...they are a starting aid...nothing more. running for a prolonged time would seriously reduce there life. once the light goes out on the dash there out.
Most of the viper alarms do have the input fot the wait to start light but you can't connect into it in a 6.0 the light is on a pc board in the dash.You must use a set delay time and long enough crank time for it to work. I've heard from more than one person that the glow plugs stay on after starting for some reason and there is a voltage change after about 1.5 to 2 minutes that seems to coincide with it not sure.
Just finished the install. I did install the 528t to be able to adjust the timer. Works great. I have it set at appox. 20-25 sec because we drive a lot in the local mountains and the glow plugs take longer with the colder temps and altitude, so that should be plenty of time either in the mountains or in the valley. It's great, just tried it out going for dinner, truck was warmed up (engine and inside cab) and ready to go when I walked out the door. Thanks for all the info on this topic.
easy way to figure that out is find the 12v hot coming into the glowplug rail stick a test light on it if the signal stops once the light goes out then there done.
WishIhada7.3- great idea simple and reliable. I will have to look for a test light and see what happens. If anyone has one and does this test, please post results.

Not so, when the light goes out on the dash it simply means its time to crank the engine. The glow plugs stay on for a time after engine starts to help clear up start up smoke.

i have to disagree with ya there, the light on the dash does not determine the length of the glow plug "on-time" the light is just a reminder but the pcm determines the real length. but i see your point.
The glow plug system is electronically controlled by the PCM. If the oil temperature is below 55°C (131°F), the PCM will energize the glow plugs immediately after the key is placed in the ON position. Then, depending on the readings from the EOT sensor and the BARO sensor, the PCM determines how long the glow plugs will be on.
Glow Plugs — PCM-Controlled
The glow plugs are located in the cylinder heads, under the glow plug wiring harness.
The glow plugs are self-regulating. If the engine oil temperature is above 55°C (131°F), the powertrain control module will bulb-check the WAIT-TO-START lamp but not energize the glow plug relay.
The glow plug ON time varies from 0-120 seconds depending on battery voltage, EOT and BARO.
The glow plug ON time is independent of the WAIT-TO-START lamp ON time.
