datzenmike Posted November 11, 2023 Report Share Posted November 11, 2023 My 521 sheared the 2 bolts off in the block. A buddy made up a bracket and moved the alternator to the other side under the distributor. God, that was in '77? 1 Quote Link to comment

Crashed I never seen that part listed before good to know. however L16 blocks are 2 bolts in the block and use the smaller bolts unless it generic and fits 2 AND 3 BOLT ENGINE BLOCKS zcardepot is a great one stop shop site You sure did!

andyZ00m Posted November 12, 2023 Author Report Share Posted November 12, 2023 Alright, todays adventure was replacing alternator and cleaning and restoring fuse bock, new battery and attempting to source battery cables. Got the new alternator and parts but was having trouble finding the right battery cables. Specifically, the + lead has the fusible link and goes to starter, and ground lead has a secondary lead from the engine block to the alternator ground. This cable I will need to make custom as I cant find a shop tht has something. Rock auto has parts but not the right thing. I used the original cables for now as they work and they will be replaced next weekend. Another challenge was the belt for the fan/alt, the part as spec was too short for the new alternator and also the shape of the V ate up some length versus the stock part. Had to get an extra inch belt to clear the new alternator from the block and still have play to tension the belt properly. Cleaned and sanded all electrical contacts, degreased and deoxit everything electrical all the cables. Soaked fuse block and scrubbed/sanded the leads for the output and input. Once new parts were installed and fuse block reassembled, the alternator is putting out about 13.8+VDC @ 1100 RPM with full lights on (choke about 60%) and all the electrical is working (accept the work light inside the engine compartment, need to chase that fucker down). Heres some photos! https://imgur.com/S23U3FE 2 Quote Link to comment
banzai510(hainz) Posted November 12, 2023 Report Share Posted November 12, 2023 (edited) I usually get a battery cable like this, but of coarse it will be shorter. short as possible. O rileys has a assorment of sizes. + side cable to the fire wall. then use that extra wire off the lead clamp side to the fuse box. Youll have to extensd that. I think I made or put a male/ female splice so I can take it off. I have to look. https://www.oreillyauto.com/detail/c/super-start/battery---accessories/battery-cable/97f343b1aaa1/super-start-4-gauge-72-inch-battery-post-cable/ss01/08499?pos=5 the neg side battery cable just went to the head and thats it.(that lifting fixture) there is a small black wire that goes to the alternator case. 8mm srew/bolt Might be good to add a ground wire from motor to the body.

banzai510(hainz) Posted November 12, 2023 Report Share Posted November 12, 2023 I think thats a Chinese alternator. I had to squeez the bushing one way to fit the 521. if a 510 would fit fine or viseversa on the back ear of the alternator. I used a vice and big socket I got 2 of those alts as one died already. get the rig lighter volt meter ! 1 Quote Link to comment

banzai510(hainz) Posted November 12, 2023 Report Share Posted November 12, 2023 my 621 had a cig lighter. with these junk alternator you need to monitor the output. cause by the time the IGN light comes ON your trying to find a way home. soon as I suspect something ike a low output with Lights On or somethinglike that I drive home on the battery as Im not to far from home with in 20miles. with NO lights on should be able to make it home Quote Link to comment

I imagine that I would have been real sad if the battery had finally pooped during that adventure. Found one of rock auto says new Hitachi. 88$ maybe should have got this guy. Easy enough to check with a multimeter every couple weeks and make sure its still doing its job. Edited November 12, 2023 by andyZ00m Quote Link to comment
datzenmike Posted November 12, 2023 Report Share Posted November 12, 2023 The ground goes to the head which grounds the block and the transmission so that takes care of the starter. For everything else on the body, (specially the voltage regulator) they need a return to ground so run a thick wire from anywhere on the block to the sheet metal. NOT the frame! it's isolated by rubber mounts (leaf springs, shocks, mounts) from the actual body. Quote Link to comment
thisismatt Posted November 12, 2023 Report Share Posted November 12, 2023 Frame needs a ground also from block or cab, since rear lights need their ground also 1 Quote Link to comment
andyZ00m Posted November 13, 2023 Author Report Share Posted November 13, 2023 The main star ground is connected to the body via a large screw that also mounts the voltage regulator. This is where the fuse ground and the ground lead from the alternator connect together. The indicator flasher is def dead. Will this one replace it? https://www.rockauto.com/en/moreinfo.php?pk=4916712&cc=0&pt=10139&jsn=88235&_nck=Ekt6BqBF1pwlXdx0gYlm1esw98pF26vehMm%2FGG3C%2Fl2QOXSJubi7WSpUmUSdg3OxWOs2f5z9h422EONy36O0PjCuaadDqI1r86y%2FvJ1lBqxeBNhI9mMX8H1x0fHFzmF%2BKG7YKD8h756k3BtrsE6fARMKaXNp7eQFiprUry%2F3aNaQKjQsmXoMDilrLCMYgOIsMiuO7dm4JKqdyjUkyeP2%2BAdcGeIGDWdnvUJS57KpDqkxS2PnBx4VLe%2BJvDOTgUWyvIldRhw6e0PR6dxwuQc7HnsW9g6ufaiTA9Dnerwr8d96LgWK0UENIdIjqztDS%2BMnc9n5EHcgYOURTNSPA%2F1BRwgkjSo6QyrcjUjukoHZ37CiYxvtBbNrUuEoD%2B6GrpAR Quote Link to comment

I believe it will require 1 more component .. Someone else will have to clarify .. Quote Link to comment
datzenmike Posted November 13, 2023 Report Share Posted November 13, 2023 Yup that is the remote igniter EI distributor. Nothing wrong with it and is the same as the matchbox but the remote igniter box isn't miniaturized and would be mounted under the dash. Still you can substitute an HEI module from an old GM distributor and buy an EI coil from a '78-'80 620 or S10 200sx. Just ignore the 1.6 ohm coil rating. You need the 0.75-1.0 ohm EI coil to go with this for the high output spark. 1 1 Quote Link to comment
banzai510(hainz) Posted November 13, 2023 Report Share Posted November 13, 2023 the L 16 timing plate and mount will not match that EI. will have to be rigged Quote Link to comment

I bought the Cardone reman you speak of and I can confirm that it works great but I have put very few hours of use into it. Actually it breathed new life into my truck but that is more a comment on my old distributor than anything else. Found the generic HEI module on Amazon and off I went. Very easy to set up. I had scrounged my local junkyard for distributors previously and only ended up with various pedestals and no dizzys but it meant I didn’t have to “rig” anything. Quote Link to comment

L16 521s use a different pedalstal timing plate set up. You got to find a later model so the rotor points right direction when installed. Quote Link to comment

You'd be better off with the one you posted from rock auto..... The mounting plate is easily fixed... The pertronix is really only designed to eliminate adjusting points... it's not designed to give a hotter spark.... 1 1 Quote Link to comment

No, the distributor is 4 cylinder but the cap beside it is 6. $500 is crazy amount. This ain't Kameari. Quote Link to comment

What is needed to rig this one or alter the mounting plate? It sounds like I’m going to need the remote igniter and a different coil. gunna do some research on this today. got a giant box of stuff to redo all the brakes (drums, shoes, cylinders, lines, etc) as well as new gaskets for oil pan and valve cover, LED light for the flashers (got an LES compatible flasher) and new sparks plugs and wires. Gunna try and reduce the oil leak if I can. The previous owner was a dingus he didn’t change the oil, he added oil (it overfilled). 1 Quote Link to comment

As for the plate take a look at the differences.... you need to see what your pedestal vs the distributor look like.... Usually it's just a matter of reslotting so the bolts go in and you still have the ability to adjust the timming.... Probably easy enough to make if needed....
