Hello my signal lights, gas gauge, along with the other instrument with the gas gauge section of the instrument panel. I'm thinking it's a fuse but IDK :( Thank you for all your inputs and advice!

Hello ratsun family! I was at a junk yard here in San Diego and I was wondering and I spotted a 720 with the alternator still in tact. I was wondering if the alternator from a 720 can fit and work on a 620? Tried researching and nothing can up. The junk yard closed while I was trying to take it out. The alternator looks a little different than the one I have on my 620. I should of took a picture or it! I'll be sure to come back tomorrow.

Thanks for the heads up! Much appreciated! I'll be sure to have some safety precautions will handling it

No didn't do that... I wonder that that leads too...

HUGE UPDATE... I'm an idiot... This whole time the "S" and "L" connection was disconnected on my alternator through out this hole time causing my battery no to charge. I guess I was to excited and forgot about connecting it back.. So I connected it and did the poor mans alternators test by disconnecting the battery cables while the trucks was running to see if the alternator and support it's own power. And it did! Went for a test drive and she did well. But the only thing that concerns me is that she dies out on stop lights. This is not all the time but 1 out 3 times she would bog out and RPM would get low. Why?

Having trouble locating. The regulator connection by what your saying about the color coded wiring list you gave me: Black Yellow White/Black stripe White White/Blue stripe White/Red stripe I can't find it...

So I'm thinking it's this by guess. I was looking at the diagram and notices that the color of the wire are different from my truck. Mike and you point out which ones to connect to?

So you're telling me to join 2 wires together to convert it to an internal volt. Regulator? That's all it take for the conversation? Theses wires?

What color is the external reg. wire? And where does it lead to. I'll try to track it down

I was wondering wait are these right here? It's in my glove compartment

Doesn't look like I have one

Ok so I'll recap everything from last night. After putting in the freshly charged battery the truck fired right up. Since it was the first time it started for the day I let it idle and warm up for about 15 mins. As it was idling I checked on all my wiring connections and look for and smell or sighs or smoke. There were no signs of smoke or charring. I felt confident enough to take her for a spin around the block just to make sure everything was good. Ran her, shift gears and turned on electrical components I.e high beam hazard lights and radio. 5 mins into the drive I noticed my lights were getting deemer and right when I pulled to a spot light I died... Called my girlfriend and I jumped my truck. I had the jumper cables on for about 15mins to give me enough juice to head home. Throughout the whole time since start up the "charge" light wasn't illuminated. Made it back home and it died on my just as I parked...SMH Ok so this is what's on my mind. Since I replaced my alternator why isn't my battery holding a charge? The things I did: 1. Tested battery (it was good) 2. Tested alternator (it was bad) 3. Replaced section of charred wiring 4. Replaced alternator Is it because I got the wrong battery? Is it because I got wrong battery? Is it because my setup is wrong? Hotwire from alternator doesn't lead straight to the battery Should I have an external or internal volt reg. (1974 w/l20b swap)?

I spoke too soon I'm stuck on a road near my house..

And the "charge" light is out!!

SHES ALIVEEEEEEE
