Default spark trigger stuck at 5v

(94 ms2 extra running jbperf sequential)

another up date
looks like my coils are being held at 5v the whole time while the ecu is on. Anyone else run into this issue. i have rechecked my wiring required for the mod and everthing is good. Is there a setting in tunerstudio that would hold those on like this?

Update
UPDATE
i put a 30 amp fuse and it didn't blow but there was a electrical noise(i know vague),noise ran for about 10 seconds until i pulled the fuse in fear of blowing the coils. the coils got warm but not hot. Anyone have any ideas?

im thinking that my board is always putting a voltage for the trigger. any thoughts? suggestions from here??

(94 ms2 extra running jbperf sequential) So i am now just putting in my megasquirt and ran into my first issue. my injector fuse keep popping with my megasquirt powering on (key on). I am running a 20 amp fuse is that to low? should i be running a 30 amp? Possible incorrect board mod (followed jbperf directions)?

Fuse does not pop when
key off
megasquirt is unplugged with key on

does pop when
megasquirt is plugged in key on

other notes are that the 3 led lights are always solid
running a 20 amp fuse(not sure if this is correct)

please help and thank you

Isn't there a fuse you are supposed to pull when installing a Megasquirt?

Directions. I never had any but I've heard they exist.
