A friend just blew his fusible link . The local parts store has some but they don't have model specific info . Does anyone know the amp value for the fusible link for a '71 240 Z ? I did a search but no joy. Thanks in advance . Gary

Gary. I have a good spare that I took from my car. Send me a PM and I'll mail it to you.

rtaylor. Thank you vary much for the offer. I was able to come up with the correct part number on my club's Microfiche and was able to order a few from Nissan. Being they are not that expensive and are a must have , if you blow one . I ordered 4 The part number if any one wants one is 24022 E8200 This is for a '71- 7-73 I don't remember the month for the '71. From 8-73 there are two different part numbers 24161 28500 or 24161 A0100 these two have different amp values. It may be due to the different alternators used , I don't know. Taylor again thanks for the offer. Gary:)

Hmmm. Probably something I should consider adding to my spares in the toolkit, along with regular fuses, E12-80, etc.

Depending on how original you want your car to be......

It might be more practical to use MAXI BLADE fuses in place of the factory fuseable link.

They are a lot easier to check and replace and come in a variety of ratings: -

Narva, for example, also sell FUSE LINK WIRE in an assortment of ratings as well as modern FUSEABLE LINK mountings: -

The biggest problem isn't finding a fuse or even fusible link wire, it's determining the correct rating for it.

The earlier Z's (up to 7/73) had a choice of 4 part numbers none of which show rating information. After 8/73 you have a rating choice of either 0.5 or 1.25.

Part numbers:

24022-E4101 Fusible Link, with Rubber Cover, listed as OP

24022-E4100 Fusible Link, LESS Rubber Cover, listed as up to 12/70

24022-E4102 Fusible Link, Less Rubber Cover, listed as 1/71 to 8/71 superseding E4100

24022-E8200 Fusible Link, Less Rubber Cover, listed as 9/71 to 8/73 superseding E4102

Note that there isn't any model info nor rating information.

Then:

24161-28500 Fusible Link (0.5), listed as from 8/73 for either the 2 seater of the 2+2

24161-A0100 Fusible Link (1.25), listed as from 8/73 but no model detail.

Additionally, the earlier Z's had a Datsun connector on one end and an eye-ring on the other (starter end). The Datsun connector is what connects it to the wiring harness just below the battery and by the starter. It isn't your "standard" fusible link wire which arrives with plain wire ends. (Don't forget that the gage of the wire AND it's length are both factors in determining the rating of the link.)

Later models had a fusible link "box" with a cover.

This is where it lies. If we can investigate the particulars, it might be possible to ascertain WHERE and WHAT to buy.

FWIW

This fuse link is an important part of the electrical system . I have seen 240 Zs wired with regular 10ga wire and even single strand wire that is used to wire a home. That is eliminating any safe guard to some important stuff under the dash. I am saying this for the benefit of our new members that may not know that there is a fusible link and how important it is.

I've been digging all evening, and not found any posts that list the rating of the fusible link on my 1973 240Z. I need to replace the link between the battery and the starter. Ran the battery down and had to jump start, which burnt out the link. You can't buy this thing for less than $25, and only at Courtesy, so far as I can tell. I refuse to pay that for a short little wire. The reason you pay so much, instead of building your own is two things. 1) One end of the link has an extra wide plug on it, that you can't buy in the store. 2) You can't find out what the failure amperage should be.

I was able to get it going again by wiring in a 30amp inline fuse. I tried a 20 amp fuse, and it blew. I used the old wide plug and soldered it onto my inline fuse, so that I wouldn't have to cut up the factory wiring, just in case I ever buy a real fusible link.

Does anyone thing 30 amps is too high? I figure that the alternator only produces 50 amps or so, and there are some accessories that use 20 amp fuses, so 30 should be about right for that small wire to the starter.

Also, if anyone has a cheaper source of these 1973 fusible links(or that odd width blade connector), please let me know. Thanks! A picture of one is attached.

If it is any help, Banzai Motorworks, www.zzxdatsun.com, lists the links in there on-line catalogue under the title, Customer requests, item #E-28 for 1970-1973 240z for $5.00 each. I have used these from Banzai and they work perfectly, and they would know the amp ratings for different years I am quite sure.

Great! That's a reasonable price. I'd rather buy a correct part than do my own hair-brained fabrication.

While on that site, I also found a windshield washer bottle and pump under bits and pieces. My pump hasn't worked in years. Since the pump is fairly well attached to the bottle, it seems best to just buy the bottle with the pump at that price. Unless someone sells just the pump, although I think you might tear up the bottle when you remove the pump.

Thanks so much!

I bought a new pump at the parts store , fits the bottle and all. I don't remember what it cost but it wasn't much. Shucks auto parts. They are called Krager in other places.

Any tip on detaching the pump from the bottle? Does it just pull off, or are there actually some bolts through all that rubber that hold it on?
