It seems like my glo plugs are taking an unseasonably long time to start-especially when above freezing. I've charged both batteries-but I guess my main question is...is it possible for 1 battery to be bad, the other being good-and the bad one showing charge from the back feed of the good battery?

Yeah, batteries in paralel are not the best setup because one battery naturally has a higher charge than the other and the higher charge one will keep trying to charge the other and equalize, and the other will keep discharging trying to maintain it's voltage. The best thing is to get batteries matched as closely as possible, or maybe some kind of isolator.

I believe they have a heat grid that warms the air coming in the engine.

Never use nitrous or Image

Yeah, thats the : nuke : smiley on pirate.


I have heard of some people having to cycle the on and off a few times for glow plugs to get warm enough, you might try that.

I'm pretty sure he said something on the phone about trying that, and not having much luck, i can't remember though

Forest, have you posted the question on the diesel forums?

thats a good way to kill your battery/batteries.

Forest, are you plugging your truck in at night when it gets below freezing?
Normal cycle time for the grids can be anywhere from 5 to 45 seconds depending on how cold the engine is. Once it does start don't drive it right away, let it set for atleast a minute to build oil pressure, once that happens I usually rev mine up just slightly. Depending on how cold it is out the grids will continue to cycle for 1 to 5 minutes. When you see that the grids are cycling (by seeing the voltage draw your gauge), then be sure you allow the truck to run for atleast 15 minutes or more before you shut it off, this will give the alternator sufficient time to charge the batteries back up. Short trips when its cold out aren't good on a diesel.

yea-if the temperature drops under 32 degrees I have it plugged in all night-but I don't have a problem with it starting after its plugged in...my concern is that it'll take ~45 sec. warming up in 37 degree weather after a 9 hr. workday. Before I changed my oil and left my cargo light on for 4 hrs-it only took about 15-20 sec...so my concern is that it'll have quite the difficult time starting once the temperature reaches 4 degrees.
