Hi, could you possibly explain to me whats happening with pin 25 Ground on a PMU16. Its labeled as device ground in the pinout and you recomend connecting sensor grounds to this as well. I assume there is no dedicated sensor ground. How much current is expected on this wire as a device ground? I assume that seeing as you have specified a 2A fuse for switched 12V, that pin 25 would be expected to be less than 2A?
The power consumption of the device itself is very low. I don’t think.it has to be fused, just make sure it has good ground contact. Actuall power consumption? Maybe 0.5 amp…
U should fuse every wire cause with the fuse u don’t protect the device but the wire and ur car from burning down in case of shortcircuit.
