Hi everyone,
I've done a few ECUs with Hardwire PDMs (Emtron and Link), but this is the first one showing this particular issue.
If I set the ECU power supply output to Normal Fuse, the ECU turns on and pulls 0.16A. When I change it to Instant Fuse (which has worked it the past) it trips as soon as the output is turned on.
High Fuse - 10A
Peak Fuse - 15A
Time - 100ms
Surely it can't be loading above 10A at start up?
I've tried another output and it does the same thing.
Any insight?
Cheers!
Hi, the ECU could have quite a large filter capacitor on its power supply input. This will draw a lot of current for a short period when power is initially applied.
