I let my battery die the other day, so I got a replacement. Cranked several times throughout the day without any problems. My wife was going to drive it, but it would not start. It seems to have all the battery power it needs (plus it still did the same thing after 15 minutes of charging). I just get a wierd click. I found this wierd click. It was from a black box, kinda like a relay. I held it and could feel it clicking. This box is located mounted on the black vacuum thing behind the battery. The numbers on the box are YWB 10041 C and
EMCUR1703W RTV. I called the local LR dealer, but he said he didnt have a listing on this part. Do you guys know what this part is, if you think this maybe causing my no cranking issue, and would you happen to know of a webshaite I can purchase.

thanks.

 

That is your fuel pump relay.
Put your ear to the floor in the cargo area and have your wife try and start the truck, do you hear the fuel pump coming on?

 

So is it cranking or just clicking?

 

Yeah it just clicks, once per key turn. Doesn't turn over or anything, I was hoping that the clicking box was the starter relay, cause I think that may be the problem. Do you know where thats at on the truck.

 

I think I can hear the fuel pump cycling.

 

You dont have enough juice in your battery.
Either your alternator is bad or your battery is dead.
Remember that just because a battery is brand new does not mean it is fully charged.

 

Yeah that was where I was going with that question. Leave your battery on the charger overnight. Make sure the connections to the terminal are solid.

 

alternator

 

I charged the battery all night and it did the same thing, even with the battery still connected on the 50 amp setting. I had a friend turn the key and I used my light tester and there was power at the starter solenoid (the large post), so I guess it may be bad, correct?

 

So where are we at?
Good battery and battery cables, all the dash lights come on but it will not crank?
Does the starter click?
Any sound at all?
If you turn on the ehadlights and then try and start it do they dim?
