Battery Alternator Tester
F600 ford 1990 draining battery?
This is a 1990 f600 ford 6 cyl. diesel dump. It is not the alternator because I dissconnected the wires and the keys are out of the ignition. When I take an ohms tester with the battery dissconnected and take the positive and negative terminals which would connect to the battery I get a reading very close to 0 (.023). Any ideas where this draw or short could be? This just recently happened.
Also the GVWR of this is 23,000 any idea of how much weight I would be able to pull with this with the truck being empty?
The ohm meter doesn't help... There are things in the circuit and things that draw power when the car's off (computer memory, radio memory, etc...) The current being drawn is what matters.
You can really test the alternator by starting the car and then disconnecting the battery cables. The car should continue to run if the alternator's good (be careful not to short the positive cable to a ground). Is the battery good?
After ruling out those two things, I'd try to test how much current is being drawn from the battery with the car off (put you amp meter in the circuit between the positive battery terminal and positive battery cable). If the amount seems unreasonable (over an amp or so), remove different fuses and test the current going across the 2 fuse clips until you find the faulty circuit. Remember most multimeters will only handle 10 amps or so... Don't try to test how many amps your battery puts out or what your car is drawing with things turned on, etc...
