Fuse Block Help Please

[zman112233]

I was having problems with my interior lights and parking lights saying on. A nice member mentioned to check the fuse block. After I started digging around in there I noticed the fuse block had melted. That's really no surprise from what I hear. Here's the crazy thing: A previous owner had used wood glue to hold the melted fuse block together! Obviously now I need a new fuse block. Can anyone here recommend where I can find a new fuse block? My car is a 1973 240z. I have seen that some people sell an "updated" fuse block with the new style fuses (but they seem expensive). Has anyone used one of these? Any suggestions one where to buy an orginal? Thanks to everyone for helping me out!

Given the price of the OEM Fuse Block - I'd buy the Motorsports replacement.. But that's only fixing a problem caused by something else - and that cause is still there. You need to relay the headlights, so that only low voltage is going though the fuse box and your headlight switch. You may save your headlight switch in the process as well.

I have the MSA one. And yes it is expensive, but I no longer have to worry about it melting! So far the quality seems good and I have had no problems with it. I will also be installing Dave's headlight and parking light relay harnesses when the weather gets warmer.

The replacements are $200. But read post #2 in this thread - replacing the fusebox is not the total answer. You need to fix the excessive current draw which causes the fuse to get hot.

zman and mr280,

I agree with the folks here. The problem is not he fuse box. It is what caused the fuse box to melt. I too have a '73. Someone cut all 3 of my wiring harnessess to shreds and bypassed most of everything to get it to run. The fuse box was bypassed as well with a bunch of inline fuses. I had to purchase used wiring harnesses off of ebay and merge them together. There were several places in my harnesses that were causing the fuses to blow and eventually melted the fuse box. Be careful, do not just fix the symptom, fix the problem

Thanks for the advice....I was just reading from another post that indicated that sometimes the fuseboxes corrode after thirty years and actually contribute to the problem.

I believe my problem is just years of corroded fuses. Everything actually works great now, I just figured it's ugly and prob not safe so it's time to replace it.

A fuse is only a dollar or so. But if it keeps blowing you have other problems!

Pull all the bulbs effected and clean the bases and inside the sockets as well as the connectors. Vinegar works on a Q tip . Don't forget to wipe clean with water to neutralize . This is one place a LITTLE , WD-40 is good to finish. Sounds like corrosion is causing high resistance . Gary
