ECU current draw on startup (filter capacitor?)


Recommended Posts


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?
