Resolved Replaced Alternator now blowing fuse

[hoonigane]

Today i replaced my alt with new one and 80 amp alt fuse just blown. Put in new one blew again. Did i connect everything right? And alt is 90 amp shouldnt fuse be 90amp too? The last alternator was 90amp too but it didnt blew. Any ideas?

Also all my accessories like radio windows heater and such doesnt work. They are disabled when this fuse breaks right or did I fry everything?

There has to be a short somewhere.

Where is the wire going to b terminal? You have nothing hooked up there.

Your Eclipse is the European version which may be slightly different than our USA version.
However on our 2g turbo versions, the alternator fuse is a 100 amp and yes it supply's power to the fuses for power windows, radio and heater blower which most likely is the same on yours. Check the owners manual for the proper value of your alternator fuse. But it does sound like you have a short somewhere since it always blows.

Pretty sure you’re missing the power wire to the fuse box and it’s grounded through the block

I swapped my alt for 90amp also and installed 100amp fuse. Been this way for about a year now without issues

Just make sure that yellow circled terminal really is the battery power connection and not just an additional ground point (or for a harness bracket like on ours).

Check for continuity between that bolt and ground to confirm it's not a ground.

Thank you for your replies. The issue was i i atached b terminal in wrong place. Thats what happens when you take out your alternator and put it in month later. Everythings fixed thanks
