any idea

[Maxtorque]

OK went out to start the truck. Stuck key in waited turned the key. Nothing its like someone pulled the battery. Turn the key back and remove and I hear a clicking noise from the fuse box. Pull the cover and its a relay clicking. Its the top relay on the left. Its a different shape than any other relay. Pull it and reinstall and clicking stops. Batteries are low on charge so charger is on. Could it be a low battery causing the problem. Figured it was a good place to start anyway. If anyone has any other ideas please let me know. Thanks Martin
