28Zero Posted October 24, 2004 Share #1 Posted October 24, 2004 Still haven't found out what the ratings are for the fusible links on the '78 280z. Anyone know? I'll probably end up ordering a set from MSA. Link to comment Share on other sites More sharing options...
webdawg1 Posted October 30, 2004 Share #2 Posted October 30, 2004 Found some info on the web regarding fusible links that might be of some help to everyone as far a converting from AWG to mm². Or if you know what mm² size you require/need, you can convert that back over to AWG (Fusible link wire size in AWG). Should be able to find correct fusible link wire at any local parts store, NAPA, MSA, Victoria British LTD, or other some other parts source that you might know about. Sure helps out if you have the FSM for your model year, as it usually tells you what size "fusible links" you need, and how many of each you need.webdawg1Fusible Link Conversion Reference.docFusible Link Info.doc Link to comment Share on other sites More sharing options...
sblake01 Posted October 31, 2004 Share #3 Posted October 31, 2004 Or you can try this picture from my 78, it's much quicker! Link to comment Share on other sites More sharing options...
28Zero Posted October 31, 2004 Author Share #4 Posted October 31, 2004 Great! This helps out a bunch. I had put in an "add-on" blade fuse to replace what is the black one. Been using a 35amp fuse, the biggest one I could find and it blows out in a week or so if I leave the battery connected. Cheers! Link to comment Share on other sites More sharing options...
z-ya Posted January 7, 2005 Share #5 Posted January 7, 2005 I understand what the large ones with the covers do, but whjat about the ones on the side of the relay box? I have a 78' that I would like to replace the fused links with auto-resetable ciurcuit breakers. Are the currents correct in this photo?http://www.classiczcars.com/forums/attachment.php?attachmentid=6208I thought they were like this:headlights 20Aignition 30Aigntion relay 30Aalternator 60A Link to comment Share on other sites More sharing options...
sblake01 Posted January 7, 2005 Share #6 Posted January 7, 2005 Those are how they are on my car, in fact, that picture is my car! I dont recall where I picked up the info but I always thought that red was 60 amp and black was 80 amp. Link to comment Share on other sites More sharing options...
z-ya Posted January 8, 2005 Share #7 Posted January 8, 2005 What are the fused links on the side of the realy box for, and what is the amp rating. Anyone?Pete Link to comment Share on other sites More sharing options...
TomoHawk Posted January 8, 2005 Share #8 Posted January 8, 2005 The big question for me is which one protects which circuits? I only know of the one that goes to the headlamps. BTW, why don't you have ant BROWN fuse links on your '78. Mine does, and it's in my owners book, Haynes book, and the MSA catalog.Pete-AFAIK, there are only the 5 fuse links on a '78, all under the hood. One goes from the battery (+) to the e.f.i. module, and the other four are on the shocktower, mounted to the relay cover, as in the photo.thx Link to comment Share on other sites More sharing options...
sblake01 Posted January 8, 2005 Share #9 Posted January 8, 2005 I don't know. That's how it has been since I've owned it and I haven't had any problems. I'd check into that but note the bottom line in my signature. I only know of the five you mention, also. Link to comment Share on other sites More sharing options...
