negetive ground
Negative ground.
6 volt positive ground is the answer!!!!!!!!
If your 1949 truck is a CHEVY or GMC and it still has the original electrical system, it would be 6 volt, negative ground. If it is a Dodge or a Ford with the oringinal electrical system it would be 6 volt, positive ground.
No, only Ford used positive ground electrical systems,but your 53 is probably 6 volt.
If the 49 dodge truck is still on it's original 6 volt electrical system it is positive ground. All 6 volt auto systems are/were positive ground. All 12 volt systems are negative ground.
Depends on what year it's from. On an older truck, hook the positive to a positive battery post, hook the ground to a bolt which goes through the chassis. On a newer truck, which is apt to having chassis-mounted electronics, put the ground to the negative battery terminal.
Assuming the truck has a 12 volt system, connect the batteries in parallel, that is positive to positive and negative to negative.
most semi truck in u.s.a. are 12 volt system. usually 4 12v batterys wire to get enough amps to crank engine. some older trucks were positive ground systems, most are now negative ground.
Ground strap on most Chevy engines is on the rear of the passengers side head , goes to the fire wall under heater hoses then to tne frame of the truck
humming noise is a bad ground to the radio. you may have a loose connection. connect a ground wire to frame of truck.
you sell it and buy a Chevy truck
No, but I'll tell you how to do it... Put the two batteries in the truck. Call them "1" and "2." Hook the positive cable from the truck to the positive of battery 1, the negative cable from the truck to the negative of battery 2, and the series-wiring cable (it's about a foot long, and it's got a battery clamp at both ends) between the negative on battery 1 and the positive on battery 2.
