Dean Posted February 20 Report Share Posted February 20 Hi! Not an important issue, but I’m interested to understand. Fury G4X I’ve done a few Link ECU’s with a Hardwire PDM, this is the first one with this issue. The PDM has an ‘instant’ fuse feature if you choose to use it on important outputs. When I use the ‘normal’ fuse setting, it behaves normally and pulls about 0.16A. If I use the instant fuse, the output trips straight away, even with the fuse setting at 10-15A. Is the ECU expected to pull quite a bit of current for a very very short amount of time? Cheers! Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 20 Report Share Posted February 20 Here is a quick scope capture of ECU power up at 500us/div. 10V = 1A, so a max of about 0.7A in this case. Zoomed out, that drops back to about 0.2A after about 20ms: Quote Link to comment Share on other sites More sharing options...
Dean Posted February 20 Author Report Share Posted February 20 Thanks for that. Good to know. The data logger in the PDM is only 20hz so I couldn't really see in that much detail! Quote Link to comment Share on other sites More sharing options...
