fuse box confusion
Hi,
in preparation to ever install a mini blade fuse box like Classic Retrofit or Adapt, I thought to dive into the fuse box a first time (1988 3.2 hasn't had electrical issues since I bought her several years ago...). After some reading and the Joe Engineer video about his ADAPT fuse box installation I was ready to find a similar fuse box with 21 connections 3 - 10 - 8 but that was not the case...I had like intermediate connections without a fuse ? so I counted more than 21 ... http://forums.pelicanparts.com/uploa...1682947548.png Anyone has an idea what this is ? I also found some wires connected at the bottom without a fuse...and on the other hand, did not find the headlight relays although this US car had been modified to EU specs 15 years ago apparently... |
couldn't find my picture in the first post, sorry for that...

Every once in awhile I think about upgrading my 1973 fuse blocks to the Classic Retrofit or Adapt ones, and then I think about the warning, "if it ain't broke, don't fix it!" You could end up causing yourself more trouble than you avoid. Those bullet fuses are a crappy design, but if you just change them every 10 years or sooner, you won't have many fuse problems. Much easier and cheaper and less likely to break something that isn't broken.
Now, if yer doing a whole electrical rewiring project anyway, then yeah, I'd put in the blade fuse blocks. |

Get a factory wiring diagram. It will identify which fuses are jumper together under the fuse box. This will explain all. |

The fuse box in our 911s is just not like American cars. Just be careful. |
I have a wiring diagram, but none include the changes that some previous owner(s) made...
I just wanted to know if it was rather 'common' to see added screws / connections on the top of the fuse box row... On the other hand: indeed, nothing seems broken now, so maybe better to step away from this :rolleyes: |

OTOH, If your car doesn't have a headlight relay installed, I'd strongly recommend tackling this project asap (before you start having issues with your high beam switch) |
I thought about updating the fuse blocks. Over the years with several different 911’s with bullet fuses, I have not had many problems. On my new project, 1983 911SC, I changed out the ceramic fuses with torpedo glass fuses. They seem to me a bit better with regard to corrosion. Bussmann GBC’s. I found them on ebay.http://forums.pelicanparts.com/uploa...1683052728.png
