Some never used positive ground and always had negative ground. The last year that I know where positive ground was used was in 1969 when Jaguar switched to negative.
MGB, up to 67, or further. My GT was.
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.
Vehicle Electrical System GroundingFor MOST automotive electrical systems, NO, the positive battery terminal is NOT the ground. In most vehicular electrical systems the positive terminal is the "HOT" terminal, not the ground.The NEGATIVE TERMINAL IS ESTABLISHED/USED AS GROUND, in almost all vehicles.It is important to note that there are occasionally some exceptions to this standard, and you need to determine which grounding system is used on any vehicle BEFORE messing around with the electrical system.
No, only Ford used positive ground electrical systems,but your 53 is probably 6 volt.
negative ground systems have always been in use but some chose to use positive grounds as wires were poorly insulated and suffered from corrosion on negative earth systems but positive earth systems did not suffer as badly to corrosion (i heard somewhere Henry ford came up with the positive ground idea cant say for sure) in recent times insulation is greatly improved and with bridge rectifiers instead of contact rectifiers which caused more uneven power flow to the battery most decided to use the same system putting everything on negative ground for simplicity but you will always have one oddball who uses positive ground just for the sake of being different
Yes, most North American automobiles do. Positive-ground electrical systems never really caught on in the mainstream.
Electrical sytem positive ground
That depends on the vehicle. Some use negative ground and some use positive ground. Most modern cars (after 1970 or so) use negative ground electrical systems, but it's best to check the manual for the particular model of car your are working on. Typically, positive ground systems will be found in British cars such as Triumph and some really old American cars.
BEcause the electricity actually runs from The Negative side of the battery to the Positive. Electrical charge is a "Negative" charge. But the layman thought that sounded wrong and eventually even the english gave in and went to Negative ground systems.
Yes, this tractor has a positive ground system. It may have been retrofitted to 12 volt negative ground over the years though.
12 volt DC Negative ground.
