MEP-803a help finding the fuse for the FU1 Battery charging circuit for the alternato

[WWRD99]

Actually, BUSSMAN is NOT the buzz word. The buzz word is FHN26G1. That's why I put all the part numbers in the thread. You simply have to try a few part numbers or NSN's to see what pops up. Its the same with the fuse.

sorry...I tried at least 15 of the numbers...none popped up with that part number and all sites wanted part quotes and none in stock.

Now... how do we get this info stuck into the Spare parts thread??
Might as well try to keep it all in one place.

I would add it if there were 50 folks looking for it.

Dang....didn't know bussman was the buzz word to find it...I had the part number...I do find locating some parts can be a pain...I looked them up in the manual....I ordered the 8.75 one on ebay...excited to get this making power...should have it Wednesday! Thanks a ton!!

Do you have the required fuse?

I needed like 5 of them about a year ago.... 5 out of 7 machines I bought in 1 lot were missing them. luckily I stumbled across a good deal on ebay for something that looked close, but I didn't have the PN. Think it was 10 pcs. for under $20, so I bought them and was thrilled that they happened to be correct! I was figuring that if the caps didn't fit I could just swap out the whole thing. Luckily they happened to be the right ones. Makes me think there will eventually be someone else that might need one....

Ill look through my parts stash, I might have a cap...

@LightintheDark
I found mine laying inside the panel under a few wires . I’m thinking from unloading and slanting with An excavator bucket .
But I have a question, when FU1 is inserted (holder and all) is it supposed to be able to be pulled out easily (like if the set were angled when loaded or unloaded - it would fall out)

 

[Ray70]

The fuse holder should push in and turn to the right a little bit and lock in place.
The cap should have a couple little tabs sticking out of the sides that twist and lock into the body of the fuse holder.
It should not come out at all unless you push it in and turn it counterclockwise again.

Ray nailed it. If its anything other than that, replace the assembly (it might just be the cap, if you don't want to solder a new body in place). I would say they are commonly available (they WERE) but are not. Eaton BK/HKP-R is the assembly with the cap. I see lead times of 6 months right now on a lot of the electronic parts wholesalers sites.

Edit: Arrow has some stock https://www.arrow.com/en/products/bkhkp-w-r/eaton

Thank you all . I see it now . I was not pressing hard enough . Pushed right in and locked clockwise .

It’s an HKP type fuse - any HkP type will work, military is using HKP-W which has a little plastic ring to make it moisture / water proof. TM lists FHN26G1 with a 125V 30 amp fast acting glass fuse 6.3x32 mm. F03A125V30A.
I found the fuse hard to find, the. 6x30 are easier to order.

I bought this one and the cap fits perfectly on the originalfassung body , it’s charging the batteries now when the genny is running :
