What would be a way to use a Ammeter current meter to track down shorts?
I was thinking since shorts are really "High current" that a Ammeter might isolate shorts better
The theory i would think is keep placing the Ammeter in each section from input to output until you read a really High current, than that would be the faulty defective stage?
SHORTS cheat sheat:
If the current is low in that stage/section than its GOOD
if the current is really high in that stage/section than its BAD
(we isolated the faulty defective stage)
Does this sound right?
Its hard to tell with a volt meter or using volts to find shorts , i was thinking a current meter would be easier to find shorts
How would u guys use a Ammeter current meter to track down shorts or isolate the area where a short might be?
If there is a Short to +VCC, does it make all the stages/sections have really high current?
If there is a short to Ground, it only affects that defective stage/section , so the current is that defective stage would be LOW while the other stages before and after are HIGH?
::Not cut traces to use a Ammeter trick::
1.) I read a trick that if you take a 1 ohm resistor plus use your Ammeter in series ACROSS any trace on a PCB in parallel that it will give you the current reading rating for that trace/path without cutting the trace
is this true or sound right?
