92 silverado not charging after new alternator and battery
maby it is charging,how do you know ,by the red dash light ,maby?? while running disconnect one bat, wire . if stalls out ,no charge if still running its getting power from alt. to run everything from the alt, may be harness wire break from alt to bat likely in ing. switch, jiggle key while running,just guessing but i am good at this stuff at least my dog agrees
It is not impossible for your new alternator, or more likely the built in regulator, is bad. That happens. The '92's did not have an external regulator, and check all connections, especially battery terminals
Thanks David, Second alternator New not rebiuld and same results. Meter shows 12.75 vdc @battery and 13.8v when running no load. Connections @battery cleaned. Amp guage always showing less than 11v Charging should show more than a mere 13.8 shouldn't it.????Also have Brand New Interstate megatron. I just don't know???
7Jimmy7, Thanks, Alternator will run truck with battery disconnected but its showing a discharge @ amp guage inside?? no light. connections were cleaned @ battery.
13.8 is well within what is should be putting out, it's fine. While charging the amperage will go up, not voltage. Under a full load charging a battery depending on what the alternator is rated, could be as high as 60 amps or more, but voltage remains constant
