Hi Gang, I was wondering if anyone could give me some guidance on this.
I have the TS-30A Short killer. I detected a short on a capacitor on laptop motherboard, when I inject voltage to either end the short killer beeps and shuts down. I assume both ends of the capacitor are grounded?
If that is the case where to inject voltage to view heatspot under thermal cam? if both ends of capacitor are shorted?
Also, what is max. time voltage injection should be injected? a few seconds? more?
thanks!
It would seem like some protection circuit of the short killer is kicking in causing the device to shut down. Short killers usually have 3 protections circuits within Over Voltage, Over Current, OVer temperature. So in your case it could be over temperature.
A simple way to test this would be keep the voltage low 1V and short the two terminals of the SHort Killer, it should draw 30A and ideally it should not shut off. If it shuts off then there is a issue with the short killer.
Ideally dont leave the short killer connect for than a few seconds especially if you are seeing a huge draw of current.
