Hey, earlier today I took the truck out for a little spin to a friends, truck started fine and I only drove for about 10 minutes and came home because he wasnt home, but when I hot home turned truck off and tried to start it 15 minutes later, the plugs glowed fine and radio and all that worked but I got a click like the battery was dead. I opened the hood and say a wire moving around loosly next to the right battery, it had a brackey on the wire like it should have been attached to something but it wasnt. I bolted it down to a nearby nut and tried with no avail. Any ideas?

Starter was replaced in feb.

Wire the one with the black top on it I don't know what it does:

that heavy black wire goes to your other battery. Loose connection could give you enough power to run accessories, but high amp demand from starter will burn out a weak connection. clean/retighten battery terminals.Edited by: Texas Diesel Guy

<font face="Arial, Helvetica, sans-serif">Heres a better diagram. I will clean and tighten terminals though.</font>

It looks like your pointing at a breather hose with a check valve. I can't say for sure but if you're K2500 it might be the front differential breather hose.

QM is right, thats just a rubber hose to the front diff.


I'm sure that the heavy wire your showing is supposed to be routed over the rad to your other battery, can you take a pic of the connector at the other end, as well as your battery terminals and ground straps on the block?Edited by: Texas Diesel Guy

Your loose wire is not a wire at all i think. Looks like a vent tube that runs to your front differential.

I think I see what you mean now, the 'bracket' on your 'wire' is nothing but a hanger on a hose, right?

Yes I don't have the lingo down though.

In the past when it didnt restart shortly after stopping i jiggled the wires around and it started.

checked all your batt posts and grounds and still found nothing?

I've had this problem. Top post batteries won't give you as problems.

The connections seem clean to me, I tried switching to one of the tractor batteries with no luck.

I couldnt get a good pic of the grounds but they look fine.

radio still working? check starter wiring.

Radio plays fine and all lights are bright, glow pugs glow quikly.
Any other time something like this started all lights were dmm, glowplugs took forever and the buzzing was a different noise.

I will check starter tomorrow when its bright out.Edited by: mcveighr

Check your fuseable links, Should be one in the wire to the starter i believe or maybe one on the firewall at a J-block. Use a test light to see if the start wire has power when the key is turned to start. if not trace it up and find the break. You may also use a remote starter switch, push button with 2 wires to bypass the start wire just to see if the start and engine will turn over. Let the key in the run position and truck should start if all else is well.

i think i can see some more corrosion on the doubled positive side terminal. big prob for these trucks. take it loose and clean it till it shines. that goes for all of them.

I thought I saw that too, on your passengerside battery it needs cleaning on the terminals with a wire brush. That green colore is corrosion.

that particular terminal on my blazer ate through the stud. i got brass rerplacements at advance auto parts. shorts and longs and they come with an xtra stud and nut to hook up accessories.

I shined em all up and that one was really hard to get it all off, and it seems to of fixed it.

I apoligise for my newbie comments, and thank you for the advice.

glad we could help. rattle and roll!

glad to hear another truck is on the road again
