How hot does an external regular usually run at temp wise
I got a new one an when i turn the key on accessory or run it goes up to about 120 is this normal
I have been having a random issue for the last year of my car stalling out then not wanting to start until it cool off
Then it starts right back up
Since i have changed my electronic magnetic part in my distributor,Coil,Battery,Voltage regulator and pulled every fuse and un plugged any accessory and the regulator still gets hot to the touch i have a ground wire on it also it also has the rubber washers on the regulator
I am at a loss
My car has run good for years but this last year has taken its toll on me
Thanks

Unless you are a stickler for originality, why not convert to a modern alternator with a built-in regulator? Once I did that my charging issues disappeared for good.

If it's stalling because the battery is discharging from the alternator not charging or under charging that's one thing. If the system is charging fine and the car stalls. You have an entirely different problem.

As for not starting until it cools off...show me a Firebird owner and I'll show you a "No start when Hot" issue at some point in their lives.

Big battery cables, 1 Gauge in my case, solved that issue using an Autozone remanf. starter.

I just read that if you are in RUN and the engine is NOT running, you are draining the battery through the alternator. The regulator is supposed to maintain a certain voltage coming from a running alternator. Have you tested the alternator? Running, it should be around 14 volts. As for hot stalling, a few common issues are possible. If the heat riser valve on the pass side exhaust manifold is stuck closed, all the exhaust from that side is forced to pass through the intake manifold, under the carburetor, and that will actually boil the fuel, causing a stall. If you are running a GM HEI, the module is susceptible to heat causing it to fail until it cools down. That is why they use some heat sink grease under the module to dissipate the heat. Back when HEI was new, GM suffered a lot of warranty problems until they figured out the grease thing. A poorly situated external coil can get hot, shut down, and seem fine once it cools off. This is about a running hot stall. A heat soak non-start is different. A hot car is shut off, the starter gets over-heated from the exhaust pipe or headers, and won't start, or labors to start. Once it cools off, it starts up fine.

Thanks for the replies
All the info has been very helpful
I ended up replacing the new external regulator (mechanical) one with a new electric external regulator
Got a tip from the local starter and alternator shop about that didn't know there was a difference
If i do have anymore issue i think i will go to an internal alternator
So far it seams to have solved the issue
I also tightened up all my ground wires
I also turn on my electric fan when the car starts to get a little warm and that cools down the regulator also with the air blowing around it
I think the carburetor is giving me some issues also so i will be rebuilding it soon
Checked my distributor cap and rotor also looks like the rotor metal piece was not quite high enough so i raised it up now its starting much faster on initial start up
Thanks for this site!!!
I have been a long time site member but its been a while since I've been on
Will try to be a little more active to help others
Thanks Much
