best way to test an alternator?
The problems experienced:
* The tractor would start, and "lunge" forward but never actually go any go further than 4 feet.
* reverse does absolutely nothing.
* hydraulics work fine
* Engine would start in any gear, when it should only start in neutral.
* Replaced a few dead fuses and a missing relay but these did not change anything important.
* oil / hydraulic fluid was very low, we fixed that.
* this lunging behavior was intermittent before, only requiring some wiggling of the gear shift.
* requires jumping in order to get started. Does not always crank fast enough by itself to start on its own.
Today, we plan to test the alternator to see what's going on there, It is rated to deliver 115 charging amps to a huge 12V battery. what is the best way to test this with a basic multimeter or some basic around the house parts? I measured the voltage across the battery rise from 12V up to 14V, so it would seem that it's fine, but I'm going to take that with a grain of rice. Is there a better way to measure the alternator?
