Saturday morning at 40 deg got in the truck and it turned over very slow, 2 dead batters less the 11.9v. what is the key to making them last a long time? And is there something that i need to do to the truck to help it out in the cold? i see there are some more threads out there, but the coldest we see in AL is mabey 13deg for two days.
Matt, first thing you need to do for me is to check the terminals, try turning them, if you can, they are loose and need to be removed and cleaned.. This, to me, ss the #1 cold weather issue. The next would be GPR, then battery replacement, then Glow plugs..
I listed the GPR before the batteries, because normally the batteries dont become an issue, they are just done.
Keep your battery connections spanking clean is a little piece of advice I can give you. I check mine all the time and clean when needed. Just allows for your alternator to keep them charged properly.
Last week i cleaned and checked the terminals, they where spotless, i just had the 2 new batters put in and in started up faster then i have ever seen it start. the GPR and glow plugs checks out fine, no smoke at all when it started.
Ceranking slow shouldn't be glow plugs or GPR. Bad battery connections/corroded that interfer with charging is number 1. Bad batteries can be determined by rechargeing and then doing a load test with a tester. A drain over time can be either internal to the batteries or from somethiong like a defective diode or regulator on the alternator. You want you batteries to last long, 1). don't buy Exide batteries. 2). keep the terminals cleaned, tight and coated with an antioxident. 3). check the water level in the cells regularly and top off with distilled water.
If you have not cleaned the battery post and connections in a while, that is the first place I would start. Also, clean the ground wires to the body. Mine did the same thing and after cleaning the connections, it was like new batteries.
EDIT: I just seen your new post. If all is good on the connections, I would have the starter checked.
You might want to put Noalox on your terminals the next time you clean them. I just did this based on reading it on this forum. A bottle from Home Depot will cost you ~$5 and will last a long time. It's in a blue labeled white bottle, made by a company Ideal and will be near the electric items, like spools of wire, etc. Clean your posts & clamps, coat all mating surfaces in the Noalox, and reconnect. It's a corrosion inhibitor and electrically conductive as well. Good stuff.
If your GPR is weak/toast, get a Stancor - HERE is guzzle's write-up on it along with source information.
the batters where tested and came back bad, i have them coated and the ground looks good the batters dead i think because of the cold, the store man said they where 5 years old, i guess this did not help them out. the alternator is good so i think the batters had seen there last.
