The=20 peak current draw on the LS1 coils is 9A EACH.   This can = happen on=20 startup before the EC2 can compute the proper dwell time.  = Average amps=20 is much lower during normal operation.

 

 

Prior to = any=20 discussion of fuses vs CBs; this issue needs some clarification. =  Is it=20 possible for more than one coil to be drawing this level of current at = the=20 same time?  I have 6 coils on my 20B; three on each circuit with = a 16 AWG=20 wire.  This could be frightening!

 

Al=20

 

Don't = think it is a=20 worry.   All can be on for a short time (possibly long = enough to=20 blow a fast acting fuse) but not long enough to heat a 16 ga wire=20 significantly.
