no power

[peecook]

been driving the 109 for a couple years, but changed the batteries out about 8 months ago with big napa batteries. went to start the truck and no power when i flipped the accessory. took the batteries out and hooked them to a charger. both came up with errors, so i took them to napa. they said it looks like the welds (?) on both were broken/cracked (this is what i think the guy eluded to). so, took the new batteries to the truck and hooked it all back up...and still no power.

thoughts, suggestions?

What does the voltage read on a volt meter.

and check the ground. Something came loose, fell off or is rubbing on the ground.

Check all your grounds
Make sure each battery individually is charged fully overnight and then load test each one.

Give us your readings when you can do this to help you out.

curiosity got to me, so drove back out there. the meter read 25-26 volts. the cable from the battery to the frame is in the original location and is still bolted tight. no damage to the cable from the battery to the frame.

There may be corrosion between the negative battery cable and the frame. I'd recommend taking the cables off and clean all of the metel to metal contact points. I used a rat-tail file and 400 grit sandpaper. It helped me alot.

i'll check again, but there didnt appear to be any rust around the connectors/frame. any other thoughts?

I agree with Flyingvan911.
That connection can look fine but oxidation/corrosion can occur between the cable end, cut washers, nut, bolt etc. and can give you poor contact. By cleaning it you will have eliminated one possible trouble spot. You can then proceed to test on the positive side to see where the fault may be.

I have a round brush that I can chuck into my cordless drill....it is just the ticket for cleaning the inside of the battery terminals....then I use a battery post cleaner to do the posts...this gives maximim current flow from the batteries.
Make sure the terminals themselves have a good connection with the battery cables...it helps to take them apart and hit them with sandpaper or wire brush.
Usually as a precation I remove the grounds and hit them with a brush on my 4" grinder and clean all the washers and nuts.....I also make sure I have lock nuts on all connections to keep them from working loose.
Don't forget the ground from the engine to the frame....I have had issues if it came loose.

Good luck.

I agree Clean it and all the connections from the battery to the starter.

Engine to the frame where is that one? Your talking a ground other than the radiator to the frame right?
