Scratching the 521 itch

[datson4life]

Ive had that issue where when my idle is too low, the voltage drops

with lights on it might be near 12voolts.

 

sound like the alt works key is if heater and lots of other stuff on.

 

Maybe it just needs another alt or bet cked or new batt cables or cleaned

Lights killing the engine - appears to be that the idle is too low

Gas & temp gauge being all crazy - Someone tried to do the voltage regulator swap I did a write up on but there is a burnt up wire on the PCB, this is causing my gauge issues

 

Going to fix both of those issues and heat shrink some wires. I think those two things will solve my electrical problems. Then I just need to fix the oil leak, order a coolant overflow bottle, rear view mirror and cabin light bulb.

A 521 did not have a coolant overflow bottle, but you can add one.  I just have a pop can, in front of the alternator, next to the radiator, held by the lower radiator hose.

The inside rear view mirror uses a 1/2 inch ball mount.  This is pretty common.  I have found a rear view mirror from a Mazda B2000 works really well, and I think it was made bt the same company that made the Datsun mirror.  Maybe a little investigation, and time on a junkyard, you could find a mirror with a "night" lever to reduce glare from cars behind you.

Oh really? ha ha ha... i started looking online for coolant overflow bottles but was having trouble finding one so that explains it. I saw several different oem looking solutions so i'll probably swipe one from the junkyard. Pretty sure it's half off entrance fees during holiday weekends - 4th of July is this weekend.... w00t!
