One of the coils could be bad and shorted causing the fuse to blow. Hhave the coils tested for shorting.

The fuse for Red/Light Green wire are shared by the following.

A) Ignition coil.
B) Capacitor ( near ignition coil) Disconnect this to test. A shorted capacitor can cause the problem.
C) ICM ( ignition control module ( inside distributor)
d) PCM power relay. ( Should be the constant control relay mentioned). Not likely to be a relay fault but possibly the wires leading to the relay is grounded.

I found the problem in the wireing leading to the fan motor which in turn runs to the ccrm. It was laying against the trany lines which run right behind them. I pulled on the connector that plugs in to the fan and my light went out and module started clicking so I inspected more closely and down at y were the wires came together there it was. I fixed it with no cost. How often does that happen. I want to thank you all you were very helpful. I'm sure I'll be talking to you again. Pewee

Loose wires and shorting occurs mainly when wire holding clamps are broken or not assembled correctly. The wire harnesses vibrates and either breaks or being abrased till the wire coating is worn away resulting in shorting.

Common in all vehicles.
