i put a little bit of solder on top, it dropped to 7 ohms, so it is maybe a NTC any ideas on a part number? Do you think this thing is fine? The problem I am troubleshooting is intermittent turn off, I thought it was crashing because both batteries are totally dead, so I thought to replace those first. Not sure what a peizo buzzer does when measured, but I thought they would be high impedance, so if its 8 ohms, with a 10% chance in resistance from a little bit of heat, it is the main contributing circuit element to the low resistance in the circuit I think. I am a little scared of desoldering it because of how it looks. It fits the description of a RTC device without a coating. I guess it used to look nice and something took it out. When I replace the batteries I will measure it with the device turned on to see if its contributing It powers off after it is turned on for a little bit, I am not exactly it is correlated to on time , but when it turns off, you do need to wait a little bit before it can turn back on, but I thought it was something to do with a dead battery and charge draining or whatever. The amount of time it has before it turns off is a little random. |
