Re: Dag nabbit @#$&*$!

The description of the fault is vague. Even basic electrical knowledge seems to be absent. I believe there is no way that the alternator could be involved in the short circuit as has been described. It would appear that the original and standard wiring has been modified or disturbed

The evidence provided indicates that the illustrated injector, or its close connection, has become a direct short-circuit. This is the first point to be disconnected and checked.

The injectors are normally energized in sequence via the ECU, which is supplied via the main relay, and 30 amp fuse 2 located on the main fuse compartment under the hood. This fuse is included as the first overload protection.

If everything was as OEM, fuse 2 should have blown before the fusible link and limited the ECU supply current to 30 amps, which should not have caused the fire described. Even so, the protection afforded is minimal and damage to the ECU could be expected, but as things stand, is probably a certainty

It would appear that fuse protection has in some way been bypassed. This is bad news and dangerous as gasoline fumes are present.


Ray,

I don't really have any reason to suspect the Maniac alternator to be at fault at this time. Did you do any alternator wiring upgrades or check the original wires for cracking and corrosion. I eliminated a lot of these problems when I developed the new alternator wiring configuration.
