Default DIY. Alternator Fuse.

Electrical problems, no dash lights, no power, dead alternator, etc.
Replaced the alternator and new battery, and your car still doesn't work?

It's this.
Tools needed:
8mm Socket
10mm Socket
12mm Socket
13mm Socket

Small Flathead screwdriver.

150A Fuseable link from Lexus. $23.41 Canada price.

- Remove the positive terminal from the battery. 10mm
- Take off the cover on the fuse box under the hood with a flathead
- Take off the 2 10mm bolts holding the fuse block.
- Use your fuse box cover as a bucket to hold your nuts / tools.
- The Fuse block has 2 sections. Use the small flathead to pry the 2 tabs and seperate. Be careful, they're fragile.
- Pull the smaller section up. Remove the bolts as pictured with the right sized sockets as listed.
- Take it out. Replace.

I have ugly fingers.

I have a RX 350 with the alternator fuse blown. I can't seem to be able to get it out or take the box apart. It is buried deep in the box. Can you give more detail as to how to take it apart? Thanks

The Panel should be held on by some 10mm bolts. After you remove those, there are clips holding the 2 sectional panels together. Take a flathead to it, and the panel itself should be free to move around. After that, the fuseable link is held on by a 12/10mm.

This was on a 95 SC400. So I don't know if it'll be the same for you.

You should remove the negative battery cable not the positive.

Just know the whole plastic piece comes off so you can get to the bolts. I unbolted all the top screws on top. but now realize I may have been able to pry just the front part of the front plastic case off. You have to know the bolts to the 150 amp fuse is not just on the front part, but there is another bolt on the back, so you can get to it after you lift the front part of the plastic case.
