[s-cars] Blown ECU 15A Fuse

[James Murray (QB/EMC)]

 Sr. Manny, 

Two things... 

First, the fuse should be a brown 5amp and not the blue 15aamp like the
Bentley sez... Don't take a chance of blowing your ECU.
Second, it's also possible to have a grounded POS, disconnect both from
the coils and turn ignition on, if the fuse still blows then it's
possible you have a blown POS, try again with only one POS then the
other... If they are okay, then try connecting the coils back up one at
a time.

My logic is the reverse of Bills, disconnect everything, then reconnect
until it blows... You'll waste less fuses and possible damage to the ECU
that way :-)

Sr. Manny,

IIRC this is an end of life symptom of coil.  

My stupid way to determine which one is bad, is to disconnect one coil,
try a new fuse, turn ignition on.

If fuse blows again... it's not that coil.

Repeat until the fuse does NOT blow and the coil that you have
disconnected is the bad one.

It could be a pinched wire too but a recent dyno day could have finally
pushed a coil over the edge.

Cheap fix is to replace the one coil, but far better would be to redo
all of em or try the 034 uber coil pack for about the same price, but
supposedly works well and eliminates the POS's.  All new coils make the
motor run great.
