Re: New old truck trouble
Could be lots of things but check the ground strap first.
Do you have access to voltmeter? You can get one at any hardware or auto parts store for as low as $10. If so, this is how you do it. Set the voltmeter to DC 12v or 50v mode, Measure the volts across the pos and neg terminals of the battery to make sure your new battery isn't already dead. If the needle moves, its still good. Now, touch the positive probe to the positive terminal of the battery and then touch the negative probe to any bare metal on the engine block. If the needle jumps, you have a bad ground strap. Then, replace ground strap.
