Alternator fuse, not amp fuse.

For some reason my under dash #15 fuse, rated 7.5 amps, keeps blowing. I have replaced the ELD(electrical load detector) in the under hood fuse box, I have replaced the alternator. It will blow not 5 seconds after you strat driving down the road. Everytime......


Any ideas?

Check your grounds.

...and check for shorts to ground in that particular power wire.

I had something like this but it was the wires from my si spoiler they were exposed so the neg. touched the pos. and blew a fuse which controled my horn, and brake lights. Make sure there is no bare wire.

#15 is the Alternator fuse. The ELD unit, Gauge Assembly and PGM-FI are in this line. It looks like too that the Integrated Control Unit is connectred to it as well. These sensors in then connected to fuse 15 as well:
Secondary O2
EVAP bypass solenoid valve
EVAP Canister vent shut valve
EVAP Purge control solenoid valve
VSS
Primary O2
Alternator
These are the things to check. Hope you have a Helms.

also check your wiring harness from the alternator if there is no bare wires and sometimes wires get cut underneath the intake manifold. just an idea

Thanks for the help, I guess let the hunt begin. I do have a helms, and I guess since it happend when I start to move Ill start with the VSS.
