Exclamation Wont Start.....Electrical Problem!!!!

For the last couple weeks ive been having trouble with my batteries holding a charge. They would seem to die almost overnight and turn over really slow in the morning. But it would still start up and run fine for the day. Until last week when i went to start it and it just died. When i turn the key into the on position the dinger is really weak and my lights are very dim you cant really see them including the wait to start light. Also when its in the on position the IDM relay in the fusebox under the hood clicks really loud and fast. Then if you unplug that, the GPR starts clicking.

the motor doesnt even turn over it just clicks.
ive checked all the fuses they are all good and i also checked both main ground wires off the batteries and they were also good.

Im at a loss, i hate dealing with electrical problems. Any ideas or suggestions are appreciated

Thanks!

Re: Wont Start.....Electrical Problem!!!!

Put the batteries on a slow charge. Preferably, charge each one individually by separating them in the circuit. Check the battery voltage after charging. Check each battery, with them separated from one another. Should be 12.5-12.8V, with the two being fairly close to one another. Start the truck, run until the glow plugs have cycled off and check the voltage. Should be 14-14.5V.

Next time you park it, disconnect the negative cables of both batteries, and check the battery voltage again, and note it down. Hopefully it'll still be 12.5-12.8V. After the truck has been parked for several hours, go out and check the battery voltage on each battery again, before reconnecting them. If the voltage of either or both has dropped considerably, the batteries are not holding a charge and should be replaced. If the voltage has stayed pretty close to the original (at least 12V), then there's a good chance you have a parasitic load. If you have a voltmeter with a high enough ammeter measurement capacity, you might be able to measure the parasitic load and chase it down.

i can try that after i get my truck started to find out whats draining the batteries. but right now the truck wont start, not even with jumpers cables

Re: Wont Start.....Electrical Problem!!!!

I had similar problems this fall. (not sure about clicking) When and turned batteries in under warranty. That didn't help. The truck would have very low power in the mornings and not start if it sat for couple days. I then found that the alternator was charging while running, but not enough, and over night it would draw power over night draining the batteries some. That could be your problem, wouldn't hurt to go get it tested. Could have bad Diode or just be worn out.

Re: Wont Start.....Electrical Problem!!!!

a little update...
i had the batteries checked, they checked out good. I replaced the GPR and starter solenoid and i didnt see any difference. there is still no start none of the dash lights work unless it is hooked up to jumper cables but still doesnt turn over.

one weird thing i did notice was when i open the door i can hear a clicking sound from under the dash, after a little investigation i found out that it is the keyless entry box clicking???

im not sure whats going on with this one, any suggestions are welcome!!!

Thanks
Josh

^^^^^ or the cable connections right at the batteries. That would explain why it cranks only with jumper cables.

Re: Wont Start.....Electrical Problem!!!!

just for anyone following this thread or read it in the future, i got it all figured out after taking my batteries to advanced auto parts twice and them telling me my batteries were good, i took them to my uncle who is a mechanic and he told me they were bad, so i got two new ones and my truck fired right up on the first crank.
